    Improving clouds in ModelE: Recent results and ongoing work
    An overview of model development at NASA GISS is focused on parameterization schemes relevant to cloud processes. Wholesale replacement of boundary layer turbulence and stratiform cloud schemes was accomplished with an emphasis on comparing ModelE performance in single-column model mode with large-eddy simulation results over a range of conditions: neutral and stable clear-sky boundary layers; warm cumulus, stratiform, and transitional maritime clouds; Arctic cold-air outbreak and decoupled mixed-phase clouds; synoptic cirrus; and continental and tropical deep convection cases. Forty cloud-related tuning parameters were then simultaneously varied over estimated uncertainty ranges using a machine-learning approach constrained by roughly twenty satellite data sets. A small ensemble of equally likely physics obtained from the machine learning process and one "modeler's choice" tuning with substantial changes to the convection scheme are undergoing more detailed evaluation against satellite and ground-based data sets using improved and new simulator codes. Additional large-eddy simulation cases are under development using new field campaign data sets with an emphasis on better constraining aerosol-cloud interactions in warm and ice-containing clouds.

    Atmospheric Aerosol Chemistry: Climate and Air Quality
    Despite much effort in the past decades, uncertainties in both climate impacts and health effects of atmospheric aerosols remain large. During the last twenty years, aerosol mass spectrometry (AMS) has shown that sub-micron aerosol chemical composition is roughly 50:50 inorganic and organic worldwide, with secondary highly oxidized organics dominating the latter. Parallel application of chemical ionization mass spectrometry (CIMS) has provided the first observation of molecular cluster ions involved in atmospheric nucleation, including detection of highly oxidized multifunctional (HOM) organics in the gas phase. These results will be discussed in the context of their impact on atmospheric aerosols, air quality and climate; from the boreal forest to Chinese megacities.

    The MOSAiC Expedition for understanding the processes of Arctic change
    Arctic sea ice is declining rapidly as a result of amplified change in the Arctic relative to the rest of the earth. Many coupled processes, spanning across the
    atmosphere-ice-ocean system, are either driving or responding to these changes. The Multidisciplinary drifting Observatory for the Study of Arctic Climate
    (MOSAiC, 2019-2020) was a year-long, international, scientific expedition onboard the German research icebreaker Polarstern as it drifted with this changing sea
    ice across the central Arctic. MOSAiC was designed to build our understanding of the causes and consequences of the changing sea ice through a comprehensive, interdisciplinary set of observations that are the foundation for advancing knowledge and improving multi-scale models.
    In this presentation we will follow the journey of Polarstern across the Arctic on this historic expedition. Along the way we will take a closer look at some of the key scientific analyses and activities that are bringing new insight into the coupled Arctic system. Among others, these will include a focus on clouds and their impacts on energy transfer to the surface; internal sea ice processes that affect ice growth; deformation of the sea-ice on multiple scales; and a unique process-based assessment of operational models.
