Good Morning :).I'm trying to process L1A data to L2 data in an environment where a brand new virtual machine is started for each run (and unfortunately is destroyed after the run completes, making debugging that much more ...interesting...). I'm seeing two issues that I hope you guys might ...

Thank you, Sean, for the quick response!

I'm guessing MODISA's 841-876 nm band is not one that can can benefit / use ATREM.

Good evening SeaDAS'ers :)

I'm wondering - when using l2gen, what is the difference between gas_opt=8 (noted as "H2O" in the usage message) and gas_opt=16 (noted as "use atrem (H2O)" in the usage message)?

Thank you in advance for your help!

Thank you, Tommy, for the prompt response! It looks like we're retrieving the data now.

Good morning!

I have a MODISA subscription (#2130 again) that hasn't found any data since a pass on 3/10/2019 at 20:30.

Is there an issue with MODISA data?

Tommy, Thank you for the prompt reply, both last night and this morning! Yes everything appears to be back to normal. :grin:

I have a subscription to MODISA L1A data (# 2130) that has not found any data since the 2019-02-05 at 19:45Z granule. When I go to the search CGI and do a search for newer L1A files they seem to be there, my subscription just isn't finding them for some reason???Additionally I have several other...

That worked great, thank you Sean! :)This is no longer an L1B question but since I already have this thread going I'll ask it anyway...I want to select Rrs_645, Rrs_859, Rrs_1240 an l2_flags as my custom L2 products. I see the l2prod flag in the l2gen command line help but don't know what to...

Thank you Sean, that helps! :)I'm getting an error when trying to use l1bgen_generic:>l1bgen_generic ifile=A2018175065500.L1B_LAC ofile=A2018175065500.L1B_LAC.ncInput file A2018175065500.L1B_LAC is MODIS Aqua Level-1B HDF-EOS product....Reading Thuillier_F0.dat-W- /home/seadas/ocssw/src/l2gen/l1...

By way of background I'm looking to get atmospheric corrected and geolocated radiance for the 645nm, 859nm and 1240nm channels on MODISA.I was able to convert an L1A file (A2018175065500.L1A_LAC to be precise) to L1B using the getanc.py, modis_GEO.py and modis_L1B.py scripts.The results seem to ...
