Land surface temperature determination from satellites

摘要: Methods for determining land surface temperatures (LSTs) from infrared satellite measurements are described. These include theoretical studies which provide algorithms in the emissivity and atmospheric effects appear explicitly. Experimentally derived also presented. have been determined a variety of surfaces including bare soils, partially vegetated fully by using situ mounted temperature sensors. Data both Advanced Very High Resolution Radiometer (AVHRR) Along Track Scanning (ATSR) used to compare with estimates. Single channel, dual split-window multi-angle developed. An attempt has made indicate limiting accuracy LSTs choosing simplest case flat soil uniform cover. For theoretically experimental algorithms, lies between 1 2 °C. A LST algorithm is proposed continental Australia makes use climatological profiles water vapour correct thermal data.
