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 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
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.
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 data access location has changed for the MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, Version 1 data set, available through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Users accessing this data set through a script will need to update accordingly. The new data access URL is https://n5eil01u.ecs.nsidc.org/MEASURES/NSIDC-0481.001/.
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. Additionally, the GDAL virtual format (.vrt) files have been updated to reflect updated filenames.
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 SMAP/In Situ Core Validation Site Land Surface Parameters Match-Up Data, Version 1 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include the most recent versions of Level-2 SMAP radiometer soil moisture products.
Multiple High Mountain Asia data sets are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Each data set contains different science parameters, including weather measurements, bidirectional reflectance, irradiance, reflectance, optical depth, and snow and temperature.
