<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial",sans-serif">ABSTRACT: Changes in boundary layer clouds in response to global warming as well as their interactions with aerosols are two key sources of uncertainty in future climate projections and climate
sensitivity estimation. In this observational study, we examine how the organization of boundary layer clouds into mesoscale morphology patterns (O~100 km) may modulate both cloud feedback and aerosol forcing. We utilize identifications from a supervised neural
network algorithm that categorized near-global satellite retrievals into three mesoscale cellular convective (MCC) cloud morphology patterns. At constant cloud fraction, brightness differences between morphology patterns depend in part on the prevalence of
optically thin cloud features. Environmentally driven transitions from closed MCC to other morphology patterns, which are typically accompanied by more optically thin cloud features associated with increased precipitation depletion, are used as a framework
to quantify the morphology contribution to the optical depth component of the shortwave cloud feedback. Including a measure of anthropogenic aerosol in addition to environmental controls in this regime framework provides insights into the sensitivity of aerosol
forcing to cloud morphology shifts under past, current, and future climates.<o:p></o:p></span></p>

was a NOAA Climate and Global Change Postdoctoral Fellow from 2020-2022. Her work utilizes <i>in situ</i> and satellite observations as well as large-eddy simulations and global climate models to study how clouds influence the climate through aerosol-cloud-precipitation
interactions and feedback. In her recent work, Isabel has focused on understanding how mesoscale organization of boundary layer clouds influences the climate system and how socioeconomic choices will impact our future climate through modifying regional and
global aerosol concentrations in addition to greenhouse gases.<o:p></o:p></span></p>
