MODIS 250m Processing

Thanks much Sean.
Perhaps I will request the system admin to run modis_GEO.py once so that de200.eos gets created! Then it  might work for subsequent processing I hope.

Thanks George. I checked the directory $OCSSWROOT/share/modis/static/ but I only see de200.dat.From the reasons you have listed, I think it may be about privileges! I am running this on a container on adapt where Seadas/OCSSW were installed for us! Perhaps I have no permission to write in $OCSSWROOT...

Hello,
  I just want to confirm that even when I use aer_opt=-99, Rhos will include correction for gases. Or do I have to specify this?
Thanks much.

aer_opt

Hello Sean,
  Thanks so much for the explanation.  Is my understanding correct that no matter what aer_opt I use (or use -99 for no correction) Rhos values will not be affected by it?
Thanks again for your help.
