Re: How to identify multi-layer cloud in SatCORPS?

Hello, Thank you for your interest in CERES. The GEO products, regardless of geostationary satellite, do not have multi-layer clouds in them. They are pixel-level products. Each pixel either has a cloud or does not. If there is a cloud, then the cloud properties are given. Regards, ASDC User Services

Hello vasu_007 , Have you considered level 3 data (averaged global gridded products) instead of level 2? Using level 3 will be a lot easier for you to work with. If you decide to use open_mfdataset, you may consider using the group= and/or the combine='nested' keyword arguments. Also, if you decide ...
