Good tips, thank you! At least for now I'm testing that the gbad files are are 19968 bytes or more long and start with EOSAM1 or EOSAM2. If I find that's not working I'll come up with plan B. In the case of netcdf/hdf files I have an automated test that ncdump -h doesn't return an error code. In add...

OK, this is embarrassing :oops: Our download script was retrieving html error messages instead of gbad files and happily injecting them into the production system as if they were actual gbad files. Needless to say modis_GEO.py didn't read / process them properly. Anyway, I'm off to add a trap to the...

Some time late in the UTC day 2021-10-10 or early in the day 2021-10-11 modis_GEO.py mysteriously stopped working (we hadn't manipulated the system in months). Here's an example of what's happening when I try to process almost any data with it: /marine-services/ocssw/scripts/modis_GEO.py --threshold...

Dear Sir, It looks like all of our subscriptions stopped working yesterday 6/18/2021 a bit after 14:18 UTC. Initially when we tried to download a new file it resulted in an html error message - but then new swaths stopped being posted to the subscriptions. Could you please look into it or forward th...

We have 8 different subscriptions that we normally get data from using the file search cgi (https://oceandata.sci.gsfc.nasa.gov/api/file_search/). The subscriptions get data from VIIRS/NPP, VIIRS/N20, MODISA and MODIST. All 8 subscriptions stopped returning new data between 11 and 15 UTC on 5/5/2021...

Has there been a more permanent solution to the planetary ephemeris issue described here?https://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?tid=12848When does the updated ephemeris file at https://oceandata.sci.gsfc.nasa.gov/ocssw/de200.eos end? I want to proactively upgrade our OCSSW i...

Beginning a little bit after 18:47 UTC today, every attempted download from https://oceandata.sci.gsfc.nasa.gov/ob/getfile/ has resulted getting the html error page that says Sorry, an error has occurred. Use the back button to return to the previous page or go to the Ocean Color Home PageCould some...

John,

Thank you for the quick reply!

Just out of curiosity, why does MODISA get 5 minute attitude and ephemeris files while MODIST gets 2 hour ones?

-Andrew L.

Are geo files for MODIST available for download from oceandata? If so where should I be looking?

Or does one need to make their own from the two hourly attitude and ephemeris files?

Thank you!

-Andrew L.

By way of background, we like to be able to process data entirely from LANCE NRT input as a backup for when the OBPG DAAC is unavailable.I have successfully found the 2 hourly Terra ephemeris files on LANCE (under https:// nrt3.modaps.eosdis.nasa.gov/archive/allData/61/AM1EPHNE) but I can't seem to ...
