issue on de200.eos file

Good morning

I experienced the "1 december 2020" issue related to the planetary ephemeris and I followed the instruction to download and install a new de200.eos file (as indicated here) . However, i didn’t find the $OCDATAROOT/modis/static/ directory and, instead, I copied the new de200.eos file in $OCDATAROOT/modis/static. l2gen produced again wrong lat and lon fields.

I have seadas 7.5.3 on a ubuntu workstation.

Have you some hints to solve the issue??

Thanks you very much

Fabrizio

The OCDATAROOT environment variable is defined by the OCSSW_bash.env file provided with the SeaDAS ocssw code.  It is relative to the OCSSWROOT variable, which defines the location of the installed ocssw code.  Typically, OCDATAROOT points to <seadas installation directory>/ocssw/share/.  Make sure the new de200.eos file is placed in the correct path, or the MODIS geolocation code will not find it (and will use the old version).
