Nespresso & Teatime - 417 DSL Commons * 3:30 to 4:30 PM Eastern Time (US and Canada) ? Colloquium - 499 DSL Seminar Room Abstract: There has been a recent surge in development of accurate global atmospheric model emulators, including full ML model emulators (FourCastNet, PanguWeather, GraphCast, GenCast) and hybrid models (NeuralGCM). Evaluation of these models has generally been focused on forecasts, mostly with 1-10 day lead times. However, forecasts rely on accurate initial conditions that, in the context of operational weather prediction, generally come from a cycled data assimilation (DA) system. While there have been a few DA studies that utilize emulators, these studies have focused on synthetic observation experiments. Here we present what is, to our knowledge, the first study of a DA cycling system using ML models to assimilate real observations. A reduced observation network consisting of only surface pressure observations is assimilated into ML models (including NeuralGCM, PanguWeather, and GraphCast) using an ensemble Kalman filter. This experiment design provides an informative test case since the performance of the DA system relies on accurately capturing ensemble covariances to update unobserved state variables, where the observed variables may or may not be part of the loss function used in the optimization process. Results will be compared to those from experiments that cycle with a coarse-resolution version of a fully physical model, NOAA?s operational Global Forecast System. The ML models suffer from stability issues, and even when stable do not perform well compared to the GFS, even when run at higher resolution, suggesting that changes in the way these models are trained will be necessary for DA applications.

Over this time frame, hundreds of monumental complexes were constructed amidst the marshes, bayous, and river levees. These complexes fundamentally reworked the ecology of the deltaic plain, creating topography and enhancing biodiversity, whilst also creating novel viewsheds from which to see and be seen. These monumental places were engineered to last and they were emplaced to reflect the anthropogenic and natural worlds. In the French colonial era, the river delta became the seat of a new empire, an entrepot from which massive wealth was generated, and which rested on the backs of enslaved Africans and rapidly disappearing Indigenous communities. My most recent excavations are a community-directed effort to highlight the daily, material, and religious lives of enslaved Africans and free people of color. Herein, I review the archaeological history of the Mississippi River Delta, showcase my excavations, and articulate a path forward for a reciprocal archaeology that reaches as far forward into the future as it does into the past.

All adverse consequences of climate change rise and fall with the global energy budget, so a necessary first step (before we can predict regional change and regional probability of extreme weather) is to beat down the uncertainty on the global energy budget as much as we can. Reducing uncertainty has proven surprisingly difficult for a large number of reasons, but one thing links many of them: forces acting in opposite directions. This is true for the anthropogenic forcing of the climate, which is the net of a warming (greenhouse-gas) and a cooling (aerosols) component; physical mechanisms contributing to the forcing (e.g., precipitation and evaporation responses in clouds); different lines of evidence (global models, observations, process models, and theoretical understanding) that do not always agree; and scientific methods, which are torn between making the measurements and building the models that are possible rather than the measurements and models that would reduce climate uncertainty. In this talk, I will give examples from the aerosol-cloud world of the uncertainties caused by these opposing forces. I will point at ways we could embrace, rather than wrestle with, uncertainty and use it to point out where we need to understand the climate at a deeper level.

Colloquium - 499 DSL Seminar Room Abstract: We will explore Fire Dynamic Vision (FDV), a novel analytical tool designed to enhance the quantitative analysis of fire spread and plume behavior through video data. FDV processes videos captured across various image types, spatial scales, and data collection configurations to extract velocity distributions, which are then analyzed to uncover statistical patterns in fire dynamics. With FDV, we seek to either confirm or challenge our existing understanding of concepts within fire science and offer validation or potential updates to fire spread and plume behavior models.

Nespresso & Teatime - 417 DSL Commons * 1:30 to 2:30 PM Eastern Time (US and Canada) ? Colloquium - 499 DSL Seminar Room Abstract: Molecular dynamics has been around for over 60 years. It is used in all scientific domains, from physics and chemistry, through materials to life sciences and medicine. Nothwithstanding its widespread applications, the enormous quantity of supercomputing cycles expended on it and the vast number of publications which feature it, in its conventional form of use classical molecular dynamics suffers numerous limitations, the central one of which is its lack of reproducibility. This raises fundamental questions over its scientific credibility alongside practical issues concerning why it does not deliver actionable predictions. In this talk, I will present a conceptually distinct interpretation of molecular dynamics from that which is available in textbooks, lectures and scientific papers, one based on its chaotic nature, its relationship with ergodic theory and with thermodynamics. While transforming the theoretical underpinning of molecular dynamics, this reconceptualisation also provides an immediate and practical route for making rapid, accurate and reliable predictions based on a suitably modified version of the method.
