Level 2 parameters, which represent geophysical properties such as Aerosol Optical Depth (AOD), are computed by each polarimeter team. We hope to compare these results, and to perform retrievals using generalized algorithms that can be used with all instruments.
 
This page will develop as progress is made. Until that time, see this spreadsheet for lists of scenes that have been included in Level 1 intercomparisons, and are therefore ideal for Level 2 analysis.
