Due to planned system maintenance taking place on Wednesday, October 5 from 10 - 11 a.m. (USA Mountain Time), data set landing pages and other related data pages may be temporarily unavailable or behave unexpectedly during that timeframe.
On Wednesday, October 5, from 9 a.m. to 12 p.m. (Mountain Time), the following data collections may not be available due to planned system maintenance: AMSR Unified, AMSR-E, Aquarius, High Mountain Asia, IceBridge, ICESat/GLAS, ICESat-2, LVIS, MEaSUREs, MODIS, SMAP, SnowEx, SSM/I-SSMIS and VIIRS.
AMSR-E/AMSR2 Unified L3 Daily 6.25 km Polar Gridded 89 GHz Brightness Temperatures, Version 1 (AU_SI6)
The AMSR-E/AMSR2 Unified Level-3 6.25 km product includes brightness temperatures at 89.0 GHz. Data are mapped to a polar stereographic grid at a spatial resolution of 6.25 km for the Northern and Southern Hemispheres. This product uses the Japan Aerospace Exploration Agency (JAXA) AMSR2 Level-1R input brightness temperatures that are calibrated (unified) across the JAXA AMSR-E and AMSR2 Level-1R products.
Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.
To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.
Data subscriptions are available for select NSIDC DAAC data collections (found below). Our subscription service automatically sends you new data as they are delivered from active NASA satellite missions.
All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, using wget or curl. Basic command line instructions are provided in the article below.
