Two of the data files additionally provide bed elevation measurements. The data were derived from measurements taken by the Center for Remote Sensing of Ice Sheets (CReSIS) Multichannel Coherent Radar Depth Sounder (MCoRDS) instrument and were collected as part of NASA Operation IceBridge funded campaigns.VIEW RELATED INFORMATIONhttps://doi.org/10.5067/5NSX14QW4U4JDocumentationGET DATAhttps://nsidc.org/icebridge/portal/IceBridge PortalGET DATAhttps://n5eil01u.ecs.nsidc.org/ICEBRIDGE/IRTIT3.002/HTTPSGET DATAhttps://search.earthdata.nasa.gov/search?q=IRTIT3+V002Earthdata SearchGET DATAhttps://nsidc.org/data/data-access-tool/IRTIT3/versions/2/Data Access ToolCEOS IDN DIFVERSION 9.92019-03-272023-05-31NSIDCVersion SummaryFor Version 2 of this data set, the following changes were made:
1. Converted data files from HDF5 to netCDF4 format, with the following data structure revisions:
* Renamed the parameter dataset0 to ice_thickness.
* Added the parameter thickness_err.
* Added the parameter bed_elevation to the files IRTIT3_20110413_Russell.nc and IRTIT3_20130420_Humboldt.nc.
* Added the following CF1.7-compliant geolocation variables/attributes for improved usability: polar_stereographic (grid mapping variable); x and y (coordinates of projection). Enables automatic geolocation in software such as QGIS.
2. Changed the no-data flag value from -10000 to NaN.NSIDCMinor VersionNSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:3031WGS 84 / Antarctic Polar StereographicEPSG:3413WGS 84 / NSIDC Sea Ice Polar Stereographic NorthNSIDCLevel of ServiceBasicNSIDCFull Dataset CitationWu, X. 2019. <i>IceBridge Radar L3 Tomographic Ice Thickness.</i> Version 2.
