Re: l2gen on LANDSAT 8,why I cant get NIR band?
I did l2gen on LC08_L1TP_114036_20190122_20200829_02_T1_MTL.txt, and got 7 bands including Rrs_865. Make sure Rrs_865 or Rrs_nnn shows up as l2prod in the Parfile textArea in l2gen GUI # PRIMARY INPUT OUTPUT FIELDS ifile=/Users/*/Scenes/OLI/run/LC08_L1TP_114036_20190122_20200829_02_T1/LC08_L1TP_1140...

Re: l2gen and gpt processing over mid-pacific
Yes, gpt seems to have an issue with the geographic area that crosses the date line. The work around is to do mosaic twice, resulting in two files, one for the west and one for the east. The 1st time for the region west of the date line -- <westBound>175</westBound> <eastBound>179.9</eastBound> The ...

Collocate deals with two files. You might want to try Mosaic?

Re: SeaDAS install_ocssw failed with exit code 1
It might be easier to point SeaDAS to the system's python3 by adding this line export PATH="/usr/local/bin/:$PATH" to your bash or zsh file And then make sure you have requests installed -- pip3 list If not, install requests -- /usr/bin/pip3 install requests If you still want to use /Users...

Re: l2gen atmospheric correction with mask
If you want to do l2gen with resolution=250, you need two L1B files MYD02QKM.A2016059.0235.061.2018055181559.hdf (resolution=250m) MYD02HKM.A2016059.0235.061.2018055181559.hdf (resolution=500m) in the same directory with MYD021KM.A2016059.0235.061.2018055181559.hdf.

Re: l2gen atmospheric correction with mask
Could you provide the name of the MODIS L1 file you are working on?
Did you try l2gen with the default setting, which has maskland and maskcloud checked?
