aer_opt
Posted: Tue Sep 22, 2020 4:22 pm America/New_York
Hello,
I am trying to use all available optical sensor data in addition to MODIS [i.e. Landsat OLI, Sentinel 2 MSI, Sentinel 3 OLCI ] for a Chesapeake Bay water quality monitoring program.
I have been testing various l2gen options for OLI. When aer_opt is set to -2, the ch-a statistics differ substantially from cases when aer_opt is -1. I am not sure how to choose aer_opt for this processing. I have not tried any other options.
Another question, especially for OLI, MSI, and MODIS is about using SWIR for aer_short and aer_long. There are more missing pixels when SWIR bands are used - compared to default but the ch-a statistics are not too different.
Are there rules on how to decide these options? Particularly, aer_opt.
Thank you.
