Inversion and Validation of QingHai Lake Temperature

摘要

Making the best of the similarity and difference of Terra and Aqua satellites, the table for searching radiant temperatureis established. The radiant temperature of Terra and Aqua are imitated. It's a fact that observing angle, solar zenith angleand water column of atmosphere affect radiant temperature and the transmission, and the affection is also analysed in thepaper. Under the precondition that the similarity is found, the feasibility of retrieval of land surface temperature based onTerra/Aqua is researched. In addition, the field data of Qinghai Lake are selected to validate the retrieval algorithm andretrieve Land Surface Temperature.
