Re: Processing using l2gen: several questions

Thanks for the previous reply Sean, but I am sorry to say I am still unsure what masks have been applied to my Level 3 output. My processing steps are: After using L2GEN my L2 product shows "CLDICE" and "HILT" . I then use L2BIN and I apply "ATM FAIL" to mask data where...

Re: Seadas batch processing: Extracting l2flags and szen

Thanks for your answer George. I was playing with the SeaBASS SST data set and we have access to l2flags with this data set, which is why I wanted to have access to it with my own matchup data set. If I am right, the satellite information inside SeaBASS comes from a 10x10 km grid around the in situ ...

Re: Co-located SST data set

Hi again, Edit : I got most of the answers from playing with the data, I would just like a confirmation for: - I can not find the depth of each in situ sample in the header, are all the data supposed to come from the 0-2m surface? - Does the insitu_at correspond to atmospheric temperature ? - What d...

Co-located SST data set

Hello,

I wonder if a website refers to ocean color matchup data sets like Seabass / NOMAD etc. but for the sea surface temperature ?
I have my own data set but for MODIS-A daylight only and wanted to add some nocturnal data. However any sensors are welcome.
