Water Resources Research 32(7):2075-2086.This data set contains near-surface (< 5 cm) soil freeze/thaw status on snow-free and snow-covered land surfaces over the Arctic terrestrial drainage basin. The near-surface soil freeze/thaw status is determined by using passive-microwave remote sensing data over snow-free land and a numerical model over snow-covered land. Data are projected to a 25 km x 25 km Northern Hemisphere EASE-Grid. Version 2 of this data set greatly extends the temporal coverage and makes use of data from SMMR as well as SSM/I. Data are from October 1978 to June 2004. Data are in ASCII text format and are available via FTP.VIEW RELATED INFORMATIONhttps://doi.org/10.7265/c7f8-6t68DocumentationGET DATAftp://sidads.colorado.edu/pub/DATASETS/fgdc/ggd641_freezethaw_arctic/FTPVIEW RELATED INFORMATIONhttp://nsidc.org/data/ease/index.htmlAll About EASE-GridCEOS IDN DIFVERSION 9.92003-05-272024-02-26NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCLevel of ServiceBasicNSIDCFull Dataset Citation2003. <i>Arctic Soil Freeze/Thaw Status from SMMR and SSM/I.</i> Version 2.
