  1. Goals: -Integrate ICESat-1 and Icebridge data to improve models of spatial and temporal ice sheet surface variability -Establish datasets for ICESat-2 data modeling -Monitor changes in outlet-glacier discharge and force balance -Analyze Icebridge data collected under cloudy conditions in preparation for Icebridge- ICESat-2 comparison and cross- calibration ICESat-2 development makes extensive use of ad-hoc ice sheet surface models. By investigating elevation changes as revealed by ICESat-1 – Icebridge data comparisons I will help make these models more realistic, and will help to identify areas where Icebridge data can be particularly helpful in constraining ice sheet changes. I will also, on an opportunistic basis, analyze airborne laser altimetry data collected by Icebridge under cloudy conditions, as a precursor to future work calibrating ICESat-2 data collected through clouds.
