How to average images with clouds and ignore these cloud pixels?
Posted: Fri Feb 03, 2023 12:30 pm America/New_York
Hello everyone,
I am trying to get a monthly climate mean using 20 years of, for example, January month. My problem is that out of the 20 imagery I have 15 that have a lot of clouds. When I averaged them in SeaDAS I got negative values almost everywhere which means the cloud pixels are being taken into account into those averages. What I want is an expression that only averages positive values (chlorophyll>0). How can I write that expression in the Math Band tool?
Thank you :)
