Outdated Planetary Ephemeris in OCSSW Distribution

by alaroy » Fri Oct 15, 2021 1:41 pm America/New_York

I retrieved ocssw using

install_ocssw.py --install-dir=/tmp/ocssw-fetch/ocssw/ -b v7.5 --aqua --terra --viirsn --viirsj1

from 2021-10-12 03:08:27Z to 2021-10-12 03:11:49Z

The de200.eos file retrieved (from git?) during that process had expired.

After I figured out what was wrong I replaced it with one downloaded from https://oceandata.sci.gsfc.nasa.gov/ocssw/de200.eos and everything worked normally.

I think it would be a good idea, please, to update the one that comes with the distribution.

-b v7.5
has been replaced by the current version, which is now identified by "tag". There are likely more changes than just the ephemeris data. Using a "tag" means everyone can have the same commits. The "branch" always includes recent commits, so what you have may depend on when you installed the branch. The new

Code: Select all

install_ocssw
can list the available tags:
