Access to data

Version 3 (V3, L2V5.5.1 or L2V5.6.1, provisional) data are currently being processed and will be archived as they are completed. Processing is beginning with Nov 2000 to May 2001 because the MODIS cloudmask is available for that period. Mar-Nov 2000, and Aug 2001-present will be processed subsequently. There are some L2V5.3.1 files (Nov 1-12, 2000) on the Langley DAAC; these have a minor bug and should not be used.

Version 2 (V2, L2V4.6.2, beta) data for Mar 2000-May 2001 are still available at the DAAC.
See version descriptions above.
