Level 3 chlorophyll files unavailable

by oceani » Sun Feb 22, 2026 9:25 am America/New_York

We have been unable to download Aqua-MODIS and VIIRS level 3 chlorophyll data since 02/19. We are using a wget command to download from URLs such as listed below:

https://oceandata.sci.gsfc.nasa.gov/getfile/AQUA_MODIS.20260220.L3m.DAY.CHL.chlor_a.4km.NRT.nc

https://oceandata.sci.gsfc.nasa.gov/getfile/SNPP_VIIRS.20260220.L3m.DAY.CHL.chlor_a.4km.NRT.nc

The errors we are seeing is a 404 File not found error.

Has anything changed that we should be aware of regarding these products or their retrieval?

Please advise.

Thanks,

Mark

There was a processing backlog over the weekend and those granules have not yet been created. They should be available later this morning.
