How to obtain solar angle, solar zenith, sensor angle from SeaHawk and MODIS Aqua?

by masudocn02 » Wed Jan 25, 2023 4:14 pm America/New_York

I downloaded SEAHAWK1_HAWKEYE.20210703T133243.L1A.nc file and I created the GEO file (e.g., SEAHAWK1_HAWKEYE.20210703T133243.GEO.hdf) by using geolocate_hawkeye. I am using version 8.1 Seadas GUI. When I try to run l2gen and I select the specific products that I want (sola, solz, sena, senz) it does not run, what am I missing? I have the same problems with MODIS AQUA. I will be happy to know if there another way to get the sola, solz, sena, and senz values for the particular sensor.

You should be able to get sola, solz, sena, and senz values for SeaHawk and MODIS Aqua files. Please make sure none of sola_***, solz_***, sena_***, and senz_*** is checked on the product tree.
