Re: Download data problem

The TOAST Ozone data product has been discontinued as of May 27, 2020.
The last day of TOMS data was 2014-09-07 (N201425000_O3_TOMSOMI_24h.hdf)

The file name you should be searching for is:
N202115600_O3_AURAOMI_24h.hdf

Re: MODISA and MODIST processing schedule

There is a quality problem with our ancillary ozone data that we are waiting for the provider to correct. At this time there is no estimate as to when we will be able to deliver the refined OC products.

Re: CMR API response does not list all the Rrs band files

For ocean color files, all versions have the same file names and the newer version overwrites the older on the archive. Currently, the only way to tell them apart is by checking the NetCDF global attributes for the pversion A2021181.L3m_DAY_CHL_chlor_a_4km.nc :pversion = "2018.1" ; A202118...

Re: Question related POC monthly climatology

The monthly climatology products use the refined-calibration version of the L2 data and are available 60 to 90 days after real time. Expect the July climatology product in about 2 weeks and the August climatology in mid October.

Re: Missing data

There appears to be missing data in the direct access directory listing that the web developers are working to correct.

You can try using the file search option:
https://oceandata.sci.gsfc.nasa.gov/api/file_search/

See if that gives you the files you are expecting.

Re: Missing data

There are times when the OLCI is unavailable from our normal source and we pull data from an alternate source. When that occurs, the file names may be slightly different than what is available on the ESA archive and files that have the processing center LN1 at ESA may show MAR on our site. Can you b...

Then we produce refined-ancillary QuickLook files made with the optimal ancillary data. They tend to be available 21-days behind real time. Finally, ...
