Mapping the surface radiation budget and net radiation in a sand hills wetland using a combined modeling/ remote sensing method and Landsat thematic Mapper Imagery

Abstract

Abstract A method combining modelled values of incoming short and longwave radiation and remotely sensed measurements of surface temperature and albedo is used to map the surface radiation budget and net radiation of a wetland site in the Nebraska Sand Hills. Results indicate that the Landsat Thematic Mapper performed adequately in this case, but that the size of the study site could substantially effect the accuracy of values in other circumstances. Problems associated with deriving biophysical values from image data are analyzed. Implications of these findings in hydrology, geochemistry and climatology are discussed.
