Re: SeaDAS versioning affecting Landsat chl processing

Regarding T2022.14, aerosol_olil8_default.hdf has nwave=8, which is probably causing the error "Number of aerosol LUT wavelengths (8) is not equal to number of sensor wavelengths (7)." You probably have to wait for the fix, unless T2022.15 works. Regarding R2022.5, it seems the aerosol and...

Re: blank entry for ozone causes getanc to fail on 6/30

Sorry that temporary fix did not work. getanc should work now except you'll get a wrong status 1 instead of 2 and you'll get inaccurate warnings like this which you should ignore. *** WARNING: The following ancillary data types were missing or are not optimal: MET OZONE *** Beware that certain MET a...

Re: ocssw/processing error getting ancillary data and Atmospheric correction

We recently changed the return status of an api that getanc calls, which resulted in some inaccurate printouts regarding anc files, but you should get the anc files.

Re: process derived products with SeaDAS

As long as dales_biomass_variable is a band in your L2 file, you should be able to do l2bin on the L2 file, and then do l3mapgen on the l3b file created by l2bin

It seems that the average latency for terra att/eph has increased about 100 minutes from 7-10 hours to 9-11 hours since mid June. We are sorry to say that it's beyond our control. It's 19:46 utc now, the latest available L0 on our site is 2022180.1855 https://oceandata.sci.gsfc.nasa.gov/directdataac...

Re: Terra MODIS L1 failures

Yes, anc_utils.py script is failing to get the attitude and ephemeris ancillary files because they are not available. It seems that the average latency for terra att/eph has increased about 100 minutes from 7-10 hours to 9-11 hours since mid June. See https://forum.earthdata.nasa.gov/viewtopic.php?p...

Our team maintains anc_data_api. We are looking into the issue why the availability of att/eph for terra is delayed.
