This data set (ATL15) and ATL14 bring the time-varying height estimates provided in ATLAS/ICESat-2 L3B Annual Land Ice Height (ATL11) into a gridded format. ATL14 provides a high resolution (100 m) ...

With the migration of GLAS/ICESat data to the NASA Earthdata Cloud, transformation services will be retired and no replacement services in the cloud are planned for GLAS/ICESat L1B Global Elevation ...

The SSMIS data are used as input for this NSIDC-produced data set, which will therefore stop processing after 31 July 2025.

The left map illustrates the cumulative melt days on the Greenland Ice Sheet for the 2025 melt season through June 30. The ...

This data set provides raw lidar data from two regions of Alaska, USA collected as part of the NASA SnowEx 2023 field campaign. The study sites include a boreal forest environment in the Fairbanks ...

These data sets provide daily files of brightness temperature data and sea ice concentrations for both the Northern and Southern Hemispheres. These data products serve as a replacement for the ...

This data set (ATL06) provides geolocated, land-ice surface heights (above the WGS 84 ellipsoid, ITRF2014 reference frame), plus ancillary parameters that can be used to interpret and assess the ...

Updated photon heights to include time-dependent range bias. The mean offset between ATL03 version 4 and version 5 photon heights is on the order of 1.2 cm. See more details in the user guide and/or ...

What is the cryosphere? The cryosphere refers to Earth’s ice in all its forms. The term comes from the Greek word for icy cold—krios. The cryosphere includes: Snow on the ground Lake and river ice ...

Explore web services, interactive tutorials, and other tools to access and work with NSIDC dataThere are many ways to access and work with NSIDC data to accommodate a wide range of users.

Surface melting on the Greenland Ice Sheet is on a slightly above-average track for the 2025 melt season, with melt along the western coast leading the way. Overall, total melt-day extent as of June ...

These data are reconstructed seasonal Antarctic sea ice extent (SIE) for 1905 through 2020. They are provided along with uncertainty estimates and metadata that describe aspects of the reconstruction ...
