Data Updates
The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) decommisioned the Binary Data Subsetter on 01 August 2017. Access to all ICESat/GLAS binary data products at the NSIDC DAAC was removed on 01 August 2017. ICESat/GLAS data remain available in HDF5 format.
NASA IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies data for 2016 Antarctica are now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Additionally, on July 26, 2017, the entire IceBridge IGGRV1B data set was replaced with re-leveled data to ensure consistency within the entire data set.
