Abstract:
Sensitivity analysis is a vital tool in the modeling community to identify important and influential parameters for model development and improvement, and variance-based global sensitivity analysis has gained popularity. However, the conventional global sensitivity indices are defined with consideration of only parametric uncertainty, but not model uncertainty that arises when a system?s process can be represented by multiple conceptual-mathematical models. Multi-model sensitivity analysis has gained increasing attention for advancing our understanding of complex Earth and environmental systems with interacting physical, chemical, and biological processes. Based on a hierarchical structure of parameter and model uncertainties and on recently developed techniques of model averaging, we developed two new process sensitivity indices for identifying important and influential processes. The indices are designed to answer the following question: how can we identify important and influential processes for the explicitly proposed process models and the probabilistically defined random parameters? A computationally efficient algorithm was also developed to reduce computational cost for the indices. To further reduce computational cost, we developed a new global sensitivity analysis method, called multi-model difference-based sensitivity analysis (MMDS), which can screen noninfluential system process from further investigation such as model calibration. In this seminar, I will present the three methods in a context of environmental modeling with numerical implementation and evaluation. The methods  are mathematically and computationally general, and can be applied to a wide range of problems of numerical modeling.

"New insights for oceanic iron biogeochemistry from iron isotopes: 10+ 
years of the GEOTRACES Program"


Abstract:

The micronutrient element iron plays a major role in setting the 
patterns and distribution of primary production and carbon cycling 
across the global oceans. As such, understanding the sources, sinks, and 
internal cycling processes that drive the oceanic distribution of iron 
is key to unlocking the role of iron in the global ocean and climate 
system, whether today, in the geologic past, or in the 'anthropogenic' 
future. In the last decade, stimulated largely by the International 
GEOTRACES.? Program, dissolved iron isotope analyses of seawater (and 
source materials) have emerged as a transformative tool for diagnosing 
iron sources to the ocean, and tracking iron through the ocean. In this 
talk, I will present an overview of the explosion of new oceanic 
dissolved iron concentration and isotope data, as well as several case 
studies that show how iron isotopes have revolutionized our 
understanding of boundary sources such as atmospheric dust, underwater 
volcanoes and vents, and marine sediments, and, remarkably, how they 
also show iron can be carried thousands of kilometers through the ocean.

Hello all,

We are starting a new seminar series this year at COAPS! The goals of these didactic sessions are to get an overview on a topic, learn something new and start a discussion, in the hopes that these would lead to novel ideas and collaborations.

For the month of January, Dr. Caroline Muller (Assistant Professor, Institute of Science and Technology Austria; CNRS researcher) will be speaking about Spontaneous Aggregation of Convective Storms.


Time: Jan 24, 2023 10:00 AM EST

Join from anywhere on Zoom: https://fsu.zoom.us/j/9206782375<https://urldefense.com/v3/__https://fsu.zoom.us/j/9206782375__;!!PhOWcWs!xDSz5b-B5uF6c8cd5PhpQSnbc-rzeq428TpTZNB2nNcZFpdjTm4LFNQLw4sM0MAmeKlqj_eqqD8JPQ$>
Meeting ID: 920 678 2375

Spontaneous Aggregation of Convective Storms
Dr. Caroline Muller

Idealized simulations of the tropical atmosphere have predicted that clouds can spontaneously clump together in space, despite perfectly homogeneous settings. This phenomenon has been called self-aggregation, and it results in a state where a moist cloudy region with intense deep convective storms is surrounded by extremely dry subsiding air devoid of deep clouds. Here we review the main findings from theoretical work and idealized models of this phenomenon, highlighting the physical processes believed to play a key role in convective self-aggregation. We also review the growing literature on the importance and implications of this phenomenon for the tropical atmosphere, notably, for the hydrological cycle and for precipitation extremes, in our current and in a warming climate.

*Model- and Data-Based Approaches for Identifying Controlling Processes 
of an Environmental System and my View of Environmental Data Science*

**

Dr. Ming Ye (mye at fsu.edu <mailto:mye at fsu.edu>), Professor

Department of Earth, Ocean, and Atmospheric Science and Department of 
Scientific Computing

Florida State University

An environmental system is open and complex, and its evolution in space 
and time involves a large number of natural and anthropogenic processes 
and their interactions. It is necessary to identify controlling 
processes and process interactions for advancing our understanding of 
the environmental system to support science-informed decision-making on 
environmental protection. This seminar presents both model- and 
data-based approaches that we have recently developed for identifying 
controlling processes. The model-based approaches use global sensitivity 
analyses, and have a unique feature of addressing uncertainty not only 
in process representations (i.e., process models) but also in process 
parameters (i.e., process model parameters). The approaches are designed 
to answer the following question: if we are not certain about process 
representations and process parameter values, can we identify important 
or influential processes for developing and improving environmental 
system models? The model-based approaches are always computational 
expensive, but can be applied to an environmental system with scarce 
data. The data-based approaches do not require developing process 
models, but use data to identify spatio-temporal patterns and the 
processes that control the patterns. This is achieved in our studies by 
using cluster analysis (one-way clustering and co-clustering) and 
/t/-distributed Stochastic Neighbor Embedding (t-SNE) methods. An 
example application will be presented for a dataset of 13,024 
groundwater geochemical measurements for 11 geochemical parameters of 
1,184 groundwater samples collected over 23 years from 29 monitoring in 
a regional aquifer. The model- and data-based approaches are an 
integration of environmental science, mathematics and statistics, and 
computer science. At the last of the presentation, I will discuss our 
research on study sinkhole lakes at Lake Miccosukee and Lake Jackson 
located in Tallahassee.


*The two figures below are for illustrating the model- and data-based 
approaches. *

environmental protection. This seminar presents both model- and 
data-based approaches that we have recently developed for identifying 
controlling processes. The model-based approaches use global sensitivity 
analyses, and have a unique feature of addressing uncertainty not only 
in process representations (i.e., process models) but also in process 
parameters (i.e., process model parameters). The approaches are designed 
to answer the following question: if we are not certain about process 
representations and process parameter values, can we identify important 
or influential processes for developing and improving environmental 
system models? The model-based approaches are always computational 
expensive, but can be applied to an environmental system with scarce 
data. The data-based approaches do not require developing process 
models, but use data to identify spatio-temporal patterns and the 
processes that control the patterns. This is achieved in our studies by 
using cluster analysis (one-way clustering and co-clustering) and 
/t/-distributed Stochastic Neighbor Embedding (t-SNE) methods. An 
example application will be presented for a dataset of 13,024 
groundwater geochemical measurements for 11 geochemical parameters of 
1,184 groundwater samples collected over 23 years from 29 monitoring in 
a regional aquifer. The model- and data-based approaches are an 
integration of environmental science, mathematics and statistics, and 
computer science. At the last of the presentation, I will discuss our 
research on study sinkhole lakes at Lake Miccosukee and Lake Jackson 
located in Tallahassee.

TITLE: Examining the dynamics and structure of rapidly intensifying tropical cyclones with high temporal frequency satellite observations

ABSTRACT: Over the past 10?15 years, considerable effort has been directed toward improving tropical cyclone (TC) intensity prediction. Despite this effort, the operational prediction of TC formation and significant changes in intensity, such as rapid intensification (RI), remain particularly challenging, as these events are typically less predictable due to being more significantly governed by rapidly-evolving moist convective processes that occur in the TC?s inner-core. However, more recently, considerable attention has been given to assess the ability of exploiting the high temporal frequency afforded by satellite observations of TCs to both potentially reduce the uncertainty of forecasts of TC RI through advanced data assimilation techniques, as well as to improve our understanding of the rapidly-evolving dynamical processes associated with these events.
This study utilizes brightness temperatures (Tbs) captured by the Advanced Baseline Imager (ABI) on NOAA/NASA?s Geostationary Operational Environmental Satellite-16 (GOES-16) and synthetic 3-D temperature and moisture retrievals created for NASA?s upcoming Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) Mission to examine both the inner-core structure and the environment of rapidly intensifying TCs at a high temporal frequency. GOES-16 Tbs from the infrared longwave window band (Ch 14; 11.2 um) are analyzed to examine the strength and location of the developing convection of Hurricanes Harvey (2017), Maria (2017), and Michael (2018) throughout their lifetimes. The evolutions of the TCs? coldest Tbs indicate that the inner-core convective activity began to increase in the 12 h prior to RI onset, primarily in 2?4-h substantial ?bursts?, while substantial convection dominated essentially the entirety of the region within 100 km of the surface center within 12 h of the onset of intensification.
While certain information about a TC?s convective structure can be gleaned from the GOES-16 Tbs, they are still inherently limited by their inability to sense information below cloud tops. The upcoming TROPICS mission attempts to address this by utilizing CubeSats equipped with microwave radiometers to examine the three-dimensional thermodynamic structure of a TC at a high temporal frequency (median revisit rates of less than 1 h). In advance of the mission, synthetic retrievals of temperature and water vapor mixing ratio generated from the Hurricane Nature Run (HNR1; Nolan et al. 2013) are utilized to analyze the TC structure over a 10-day period that includes the HNR1 TC?s RI from a tropical storm to a major hurricane. Analyses are performed to assess how accurately TROPICS may be able to describe thermodynamic profiles both within the storm and in the environment by validating against the HNR1 model data.
It is found that the TROPICS retrievals compare mostly favorably with the HNR1 data at most heights and times with errors consistently less than the proposed mission requirements (2 K for temperature; 25% for humidity). In addition, the retrievals show the ability to qualitatively track extensive dry air that is present in the vicinity of the TC. Although a substantial dry bias is present within the storm region of the TC (between 0 ? 200 km from the surface center) in the 350?550 mb layer in the TROPICS retrievals, this bias is reduced when the retrievals associated with precipitating grid points are removed from the analyses. However, despite this filtering, a significant bias remains, which suggests that the TROPICS retrievals will likely lose accuracy in regions of stronger scattering.

Title: Evolution of the core & paleomagnetosphere since 4 Ga: Modeling variations in dipole field strength and magnetic shielding on million-to-billion year timescales

Speaker: Dr. Richard Bono, Assistant Professor, Department of Earth, Ocean, and Atmospheric Science, FSU

Abstract
The geomagnetic field is a long-lived phenomenon that shields Earth's atmosphere from erosion by charged solar wind. Changes in atmospheric shielding may have had profound implications on the evolution of life. The geomagnetic field is generated in the liquid core through a convective process termed the geodynamo. Characterizations of how the paleomagnetic field changes on million-to-billion year timescales afford a unique opportunity for insights into core processes and conditions. Quantifying the strength of the magnetic field can be made through the collection of paleointensity estimates extracted from geologic materials. However, constructing a coherent timeline of the average dipole field is challenging, in part due to the sparsity of the paleointensity record. Here I discuss recent updates to the site-mean absolute paleointensity database PINT (www.pintdb.org<http://www.pintdb.org>; Bono et al., GJI, 2022) that includes records published through 2022. The PINT database is used to define a continuous paleomagnetic axial dipole moment model spanning 50 ka to ~4 Ga, MCADAM (Monte Carlo Axial Dipole Average Model; Bono et al., GRL, 2022). This model yields posterior predictions of axial dipole field strength and allows for estimation of the median field with associated confidence bounds. Using the MCADAM model, the paleomagnetospheric standoff distance can be estimated going back to the early Archean. Magnetic standoff evolution reveals that the strength of the magnetic atmospheric shield during the Precambrian was lower than the present day by about a factor of 2, reaching a protracted (~100 myr) minimum during the Ediacaran, before steadily climbing towards present day standoff distances. This suggests that for most of the Precambrian, atmospheric protections were weaker and perhaps more tenuous than during the Phanerozoic.

Bio
Richard Bono earned his undergraduate and graduate degrees at the University of Rochester, graduating in 2016, where he focused on using paleomagnetism gain insight into Earth's deep interior by measuring single oriented crystals. In 2018, he moved to the University of Liverpool, first as a member of the DEEP geomagnetism group and then as a Leverhulme early career fellow. There he worked to help bridge geodynamo simulations and paleomagnetic observations with an emphasis on deep time. Last year Richard joined the EOAS department here at FSU.

Hello all,

We are starting a new seminar series this year at COAPS! The goals of these didactic sessions are to get an overview on a topic, learn something new and start a discussion, in the hopes that these would lead to novel ideas and collaborations.

For the month of January, Dr. Caroline Muller (Assistant Professor, Institute of Science and Technology Austria; CNRS researcher) will be speaking about Spontaneous Aggregation of Convective Storms.


Time: Jan 24, 2023 10:00 AM EST

Spontaneous Aggregation of Convective Storms
Dr. Caroline Muller

Idealized simulations of the tropical atmosphere have predicted that clouds can spontaneously clump together in space, despite perfectly homogeneous settings. This phenomenon has been called self-aggregation, and it results in a state where a moist cloudy region with intense deep convective storms is surrounded by extremely dry subsiding air devoid of deep clouds. Here we review the main findings from theoretical work and idealized models of this phenomenon, highlighting the physical processes believed to play a key role in convective self-aggregation. We also review the growing literature on the importance and implications of this phenomenon for the tropical atmosphere, notably, for the hydrological cycle and for precipitation extremes, in our current and in a warming climate.

Short abstract: Abstract: Dispersive hydrodynamics, the study of 
nonlinear wave dynamics in dispersive (and fluid-like) media has 
garnered significant attention in the past decades and builds upon the 
seminal work of Gerald B. Whitham. Broadly speaking, dispersive 
hydrodynamic phenomena are characterized by reciprocal interactions 
between long (space and time) scale hydrodynamic and short-scale 
dispersive effects. In this talk, through the lens of Whitham modulation 
theory, we motivate the mathematical description of nonlinear wave 
interactions which could occur in a geophysical fluid dynamics context.

Short abstract: Abstract: Dispersive hydrodynamics, the study of 
nonlinear wave dynamics in dispersive (and fluid-like) media has 
garnered significant attention in the past decades and builds upon the 
seminal work of Gerald B. Whitham. Broadly speaking, dispersive 
hydrodynamic phenomena are characterized by reciprocal interactions 
between long (space and time) scale hydrodynamic and short-scale 
dispersive effects. In this talk, through the lens of Whitham modulation 
theory, we motivate the mathematical description of nonlinear wave 
interactions which could occur in a geophysical fluid dynamics context.

Title: Evolution of the core & paleomagnetosphere since 4 Ga: Modeling variations in dipole field strength and magnetic shielding on million-to-billion year timescales

Speaker: Dr. Richard Bono, Assistant Professor, Department of Earth, Ocean, and Atmospheric Science, FSU

Abstract
The geomagnetic field is a long-lived phenomenon that shields Earth's atmosphere from erosion by charged solar wind. Changes in atmospheric shielding may have had profound implications on the evolution of life. The geomagnetic field is generated in the liquid core through a convective process termed the geodynamo. Characterizations of how the paleomagnetic field changes on million-to-billion year timescales afford a unique opportunity for insights into core processes and conditions. Quantifying the strength of the magnetic field can be made through the collection of paleointensity estimates extracted from geologic materials. However, constructing a coherent timeline of the average dipole field is challenging, in part due to the sparsity of the paleointensity record. Here I discuss recent updates to the site-mean absolute paleointensity database PINT (www.pintdb.org<http://www.pintdb.org>; Bono et al., GJI, 2022) that includes records published through 2022. The PINT database is used to define a continuous paleomagnetic axial dipole moment model spanning 50 ka to ~4 Ga, MCADAM (Monte Carlo Axial Dipole Average Model; Bono et al., GRL, 2022). This model yields posterior predictions of axial dipole field strength and allows for estimation of the median field with associated confidence bounds. Using the MCADAM model, the paleomagnetospheric standoff distance can be estimated going back to the early Archean. Magnetic standoff evolution reveals that the strength of the magnetic atmospheric shield during the Precambrian was lower than the present day by about a factor of 2, reaching a protracted (~100 myr) minimum during the Ediacaran, before steadily climbing towards present day standoff distances. This suggests that for most of the Precambrian, atmospheric protections were weaker and perhaps more tenuous than during the Phanerozoic.

Bio
Richard Bono earned his undergraduate and graduate degrees at the University of Rochester, graduating in 2016, where he focused on using paleomagnetism gain insight into Earth's deep interior by measuring single oriented crystals. In 2018, he moved to the University of Liverpool, first as a member of the DEEP geomagnetism group and then as a Leverhulme early career fellow. There he worked to help bridge geodynamo simulations and paleomagnetic observations with an emphasis on deep time. Last year Richard joined the EOAS department here at FSU. Richard received the awards of 2022 EGU Earth Magnetism & Rock Physics Division Outstanding Early Career Scientist and 2022 (Inaugural) GSA Seth and Carol Stein Early Career Award in Geophysics and Geodynamics.

Title: Machine Learning In Earth System Modeling

Speaker: Dr. Dan Lu, Oak Ridge National Laboratory, Oak Ridge, TN

Abstract:
Predictions of the Earth system have significant societal impacts, and they are one of the main goals of understanding the Earth system across scales. However, Earth system prediction is challenging. The observing system sees only part of the Earth, so the Earth system model is required to fill out the space, time, and spectral regions not covered by observations. Earth system models have substantially changed over time, from empirical model, to theoretical model, to computational model, and now are moving to data-driven machine learning (ML) model. This talk presents four ML methods to advance the Earth system modeling. Specifically, we developed a surrogate modeling technique and an inversion-free prediction framework to reduce computational costs in the physics-based Earth system model prediction, and developed an interpretable ML model with uncertainty quantification for trustworthy data-driven Earth system model prediction. The applications of these methods cover terrestrial ecosystem model, hydrological model, and geological carbon storage.
