NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC)

Reprocessing is underway for all AMSR-E Level 3 sea ice products with data from 19 June 2002, the start of the AMSR-E mission, and will continue through 5 July 2008.

Release-28 data for the Laser 2C time period (18 May 2004 to 21 June 2004) are available for the following products: GLA01 to GLA09 and GLA12 to GLA15. This is the first public release of Laser 2C data.

Due to an error in an ancillary data file, the following Version 2 AMSR-E Level 3 snow products were removed from NSIDC's archives: AMSR-E/Aqua Daily L3 Global Snow Water Equivalent EASE-Grids (AE_DySno); AMSR-E/Aqua 5-Day L3 Global Snow Water Equivalent EASE-Grids (AE_5DySno); AMSR-E/Aqua Monthly L3 Global Snow Water Equivalent EASE-Grids (AE_MoSno).

As of 06 July 2008, Version 2 of AMSR-E Level 3 land, rain, ocean, snow, and sea ice products are now available at NSIDC, and are considered Transitional (T) or Validated (V).

Release-28 data for the Laser 3J time period (17 February 2008 to 21 March 2008) are available for the following products: GLA01 to GLA09 and GLA12 to GLA15. This is the first public release of Laser 3J data.

NSIDC has recently updated the Sea Ice Trends and Climatologies from SMMR and SSM/I data products.

Data are now available through December 2007 for the Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave data set.

Reprocessed Release-28 data are now available for the Laser 1A time period (20 February 2003 to 21 March 2003) for the products GLA05-GLA09 and GLA12-GLA15. Previously these data were released as 228 in the new file naming convention, but they have now been processed to the highest level of processing at 428.

AMSR/ADEOS-II L1A version 2 data are now available from NSIDC. The data are available from 28 January until 24 October 2003, when the satellite was lost.
