MODIS Collection 6 will cease forwarding processing as of 31 December 2022. Data for Collection 6 will remain available until Spring of 2023, but the NSIDC encourages users to switch to the newer Collection 6.1 data.
Additionally, users should be aware that beginning 1 December 2022, Terra has been failing in the L1 geolocation process. All Terra MODIS data processing has been put on hold while the issue is addressed. Aqua MODIS data continues to be processed.
The NSIDC DAAC provides access to the MODIS data and documentation at the following location: NSIDC DAAC MODIS Data Collection.
