Seasat, ERS-112 and NSCAT Scatterometer Observed Changes on the Large Ice Sheets
Abstract- Satellite-borne wind scatterometers are effective tools for monitoing ice sheets and microwave imaging techniques enable comparison of historic and contemporary scatterometer data in climate change studies.

Summary: | Abstract- Satellite-borne wind scatterometers are effective tools for monitoing ice sheets and microwave imaging techniques enable comparison of historic and contemporary scatterometer data in climate change studies. We document scattering characteristics of the Greenland ice sheet using data from the NSCAT, ERS-112 and Seasat SASS instruments. C- and Ku-band data enable characterization of frequencydependent scattering characteristics and regional melting delineation. SASS-NSCAT differences show 18 year changes in dry-snow zone extent and indicate the decadal reponse to changes in the spatial patterns of accumulation and ablation. |
