Data Announcements

The VIIRS/NPP CGF Snow Cover Daily L3 Global 375m SIN Grid, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set utilizes a cloud-gap-filled algorithm to replace cloud-covered pixels with cloud-free pixels for the purpose of estimating the snow cover that may exist under current cloud cover. The data are provided daily and mapped to a 375 m sinusoidal grid.

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) will be presenting a hands-on tutorial during the 2019 AGU Fall Meeting, hosted by the ARCUS Arctic Community Meeting Space.

AppEEARS offers a simple and efficient way to subset SMAP data sets using spatial, temporal, and layer parameters for both point and area samples.

NOAA@NSIDC is pleased to announce the release of version 2 of On-Ice Arctic Sea Ice Thickness Measurements by Auger, Core, and Electromagnetic Induction, from the Late 1800s Onward. In addition to sea ice thickness, the data set provides sea ice freeboard and snow depth on sea ice from on-ice measurements taken primarily using auger, coring devices, and electromagnetic (EM) sounding. When available, ice type is also included.

New data set release: IceBridge ATM L1B Near-Infrared Waveforms The IceBridge ATM L1B Near-Infrared Waveforms, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains geolocated waveforms measured by the Airborne Topographic Mapper (ATM) near-infrared (NIR) lidar acquired during the 2018 Antarctic campaign from 10 October 2018 through 16 November 2018.

NOAA@NSIDC has long partnered with the World Glacier Monitoring Service (WGMS) in Switzerland to improve the quality and completeness of glacier data. NSIDC’s User Services office gets questions from the public about glaciers that our data hold the answers to seemingly simple questions like “What are the largest glaciers on the planet?” Ann Windnagel set out to find answers during a stay with WGMS and found that it's not such a simple matter.

The MEaSUREs Phase-Based Antarctica Ice Velocity Map, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set, produced under the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, combines interferometric phases from multiple satellite interferometric synthetic-aperture radar systems to derive the first comprehensive phase-based map of Antarctic ice velocity.

The following data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated to version 1.1 to reflect updated filenames in the GDAL virtual format (.vrt) files: MEaSUREs Greenland Monthly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1 MEaSUREs Greenland Quarterly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1

NOAA@NSIDC has updated their September and March Sea Ice Index sea ice animations in Google Earth with 2019 near-real-time data and replaced the 2018 near-real-time images with final data. To access the Google Earth files, see the NSIDC Data on Google Earth page.

Multiple Level-1B, Level-2A, and Level-3A data sets from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission have been updated to Version 2 at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).

The AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures, Version 4 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains daily, 50-minute, half-orbit swath brightness temperatures for six channels ranging from 6.9 GHz through 89 GHz. Data are resampled to spatial resolutions ranging from 5.4 km to 56 km. Each file is packaged with geolocation and quality information, as well as ancillary data.

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is one of twelve NASA Earth Observing System Data and Information System (EOSDIS) data centers. Several of the data sets distributed by NSIDC are part of the DAAC, including but not limited to AMSR-E, ICESat/GLAS, ICESat-2, MODIS, Operation IceBridge and SMAP. If you use one or several of these data sets, we’d like to hear what you think.

The High Mountain Asia Landslide Catalog, Version 1 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated from a basic to a standard level of service. Please see our Adding clarity to NSIDC data support with new Level of Service (LoS) model article more information.

The MEaSUREs Greenland Image Mosaics from Sentinel-1A and -1B, Version 2 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated with mosaics through June 2019.
