viirs l2 processing

[mamontes]

Dear staff, here one issue when I try to run l2gen from the shell of a mac mojave. it seems like it cant find the LUTs and cal files.  Environmental variables were set including path in a profile file
export PATH="/Users/mmontes/miniconda3/bin:/Library/Frameworks/Python.framework/Versions/3.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/mmontes/Applications/seadas/seadas-7.5.3/bin:$PATH"
export OCSSWROOT=/Users/mmontes/Applications/seadas/seadas-7.5.3/ocssw
source $OCSSWROOT/OCSSW_bash.env
export PATH=$PATH:$OCSSWROOT/bin

see below. any clues? thanks in advance. Martin

Looks like the Polar Wander file is in the VIIRS NPP data directory.  Installing VIIRS NPP from the GUI or

install_ocssw.py --viirsn

or maybe this will work (which is less data)

update_luts.py viirsn

on the command line.  We will fix this oversight.
