In addition to surface altimetry measurements, the ICESat-2 mission also provides observations of the atmospheric column. Not only are the ICESat-2 atmospheric products important in understanding the context of the surface altimetry, they are also an exciting resource for atmospheric studies.

In this presentation, we will present our first analysis of the ICESat-2 global cloud properties and surface reflectivity; we will compare ICESat-2 observations with those from CALIPSO. We will show that the general patterns of the two measurements match each other well. During nighttime the ICESat-2 atmospheric data quality is on par with that of CALIPSO, while during daytime, ICESAT-2 is more impacted by the solar background. Compared to the 82 degree poleward data coverage of CALIPSO, ICESat-2 provides coverage up to 88 degree south and north. This makes ICESat-2 atmospheric data products a much needed dataset for studying polar atmospheric events.
