How can I compare the latest version of data to an earlier version of data I used for a research project?

Due to differences in science quality of the products, users are advised not to combine multiple data versions in project applications.

Version 5 (V005) sea ice data sets remain available in addition to Version 6 (V006). See the V006 reprocessing schedule for more information.

A portion of data from Version 4 (004) is available for comparison. V004 data from 29 August 2002 (day 241) through 07 October 2002 (day 280), called the Golden Month, is available for all MODIS/Terra snow and sea ice products. Please contact NSIDC User Services to obtain Golden Month data.
