Hello, I am using SeaDAS 7.5.1 on a linux server, using MODIS A. I used to batch process all the data from L1A to L3m and apply the ATMFAIL flag to hide the obvious clouds/lands/glint during "l2bin" with "flaguse=ATMFAIL \" However, it does not seem to work anymore (I processed d...

I understand now. I was using l2flags because I included visible bands along with IR/MWIR/LWIR to try to improve retrievals over noisy matchups. But I guess I will switch to qual_sst.

Thanks for the details!

Hello, my question is still up, if someone can please get in touch with me to unlock the situation? I can provide more details if required.

Thank you for the answer, I now understand 1) and 3).
However for my 2nd question, I am still a bit lost.
Any thoughts about why I fail at identifying clear sky pixels at night?

Cheers

Hello, I am using SeaBASS dataset for SST, MODIS Aqua, R2018. I have 3 questions: 1) How are the BT in the MWIR/LWIR corrected? Can you point me to the appropriate atmospheric correction document for these specific bands please? 2) When using night data (flagged as night), I have an issue at isolati...

Thank you for the answer, solving my problem ! I should have checked the header carefully.

Best

Hello, I am still looking for an answer for this question.

I have one more question that may solve my problem, is the time of the matchups in the SeaBASS SST dataset associated to a specific location (like UTC or Eastern US time) or to the matchup point ?

Cheers

Hello, I have read that the SST4 algorithm performs poorer during daylight compared to SST11 due to glint sensitivity around 4 microns mostly. I also read that it is the opposite during night time, with SST4 having better performances compared to SST11, which is why NASA's SST product are SST11 duri...

Thank you very much Sean for the explanations !

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...
