![]() ![]() Set presented here consists of maps of estimated landscape freeze/thaw In radar backscatter related to varying environmental conditions. Study (BOREAS) test sites in Canada in 1994 were analyzed to detect changes (ERS-1) over a complete annual cycle at the BOReal Ecosystem-Atmosphere Data Set Overview 1.1 Data Set IdentificationīOREAS Follow-On DSP-04 1994 ERS-1 Level-4Īcquired by the European Space Agency's (ESA's) Earth Remote Sensing Satellite Available on-line from Oak Ridge National Laboratory Distributed Active Archive Center, Oak Ridge, Tennessee, U.S.A.ġ. BOREAS Follow-On DSP-04 1994 ERS-1 Level-4 The data are providedĪs both ASCII text and as binary image (*.gif) format files.Ĭite this data set as follows (citation revised on October 30, 2002): Through application of a change detection threshold based on temporal backscatterĬhange relative to a winter-time frozen reference state. ![]() The freeze/thaw classifications were determined Theīackscatter change maps were computed from radar backscatter images covering Of landscape freeze/thaw state derived from backscatter change maps. Results demonstrated that radar provides an ability to observe thaw transitionsĪt the beginning of the growing season, which in turn helps constrain the Soil thaw onset, and possible canopy thaw were revealed by the data. Two independent transitions correlating with snow melt and In 1994 to detect shifts in radar backscatter related to varying environmentalĬonditions.
