Warren, S., I. Rigor, and N. Untersteiner. 1999. Snow Depth on Arctic Sea Ice, Journal of Climate, 12: 1814-1829.This data set contains radar echograms taken from the Center for Remote Sensing of Ice Sheets (CReSIS) ultra wide-band snow radar over land and sea ice in the Arctic and Antarctic. In addition, airborne snow measurements were taken during 10 flights over Alaska mountains, ice fields, and glaciers at the end of May 2018 by a compact CReSIS FMCW radar system installed on a Single Otter aircraft. The data were collected as part of Operation IceBridge funded campaigns.VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/irsno1b-v002-userguide_1.pdfIceBridge Snow Radar L1B Geolocated Radar Echo Strength Profiles, Version 2 User GuideGET DATAhttps://search.earthdata.nasa.gov/search/granules?p=C3187453659-NSIDC_CPRDEarthdata SearchGET DATAhttps://cmr.earthdata.nasa.gov/virtual-directory/collections/C3187453659-NSIDC_CPRDHTTPSGET DATAhttps://nsidc.org/data/data-access-tool/IRSNO1B/versions/2/Data Access ToolGET DATAhttps://earthaccess.readthedocs.io/en/stable/earthaccessCEOS IDN DIFVERSION 9.92014-03-042026-10-08NSIDCVersion SummaryVersion 2 data are in netCDF format beginning with the 2009 Greenland campaign.NSIDCMinor Version1On 17 September 2014, Version 2 data were replaced by Version 2.1. A time stamp error was discovered in the 2012 Antarctica and 2013 Greenland data. The latest leap second (July 1, 2012) was not accounted for in the GPS times for these campaigns. This error has been corrected in Version 2.1.2012-10-122013-04-2602On 10 February 2016, Version 2.1 data were replaced by Version 2.2, including two changes. In the 2012 Antarctica and 2013 Greenland campaigns, the wrong "start day" was used with most files due to a programming error. The data "time" field has been corrected in Version 2.2 for the 2013 Greenland campaigns. Note that in Version 2.2 the time field correction has not yet been applied to the 2012 Antarctica campaign data. Additionally, Version 1 2009 to 2012 Greenland data, previously in binary format, were reformatted to netCDF and included with Version 2.2. On 01 September 2016, Version 1 2009 to 2011 Antarctica data spanning, previously in binary format, were moved to ECS, and are now in netCDF format and included with Version 2.2. In addition, 2012 Antarctica data from 12 October 2012 to 08 November 2012 were added to the V2.2 collection. As of this date, IRSNO1B Greenland and Antarctica data, beginning with the 2009 Greenland campaign, are in HDF5 format.2013-03-212013-04-260NSIDCCurrent Version1NSIDCLevel of ServiceStandardNSIDCFull Dataset CitationPaden, J., Li, J., Leuschen, C., Rodriguez-Morales, F. & Hale, R.
