Abstract
The QinghaiTibet Plateau plays a very important role in studying severe weather in China and around the globe because of its unique characteristics Moreover the surface emissivities of the QinghaiTibet Plateau are also important for retrieving surface and atmospheric parameters In the current study a retrieval algorithm was developed to retrieve the surface emissivities of the QinghaiTibet Plateau The developed algorithm was derived from the radiative transfer model and was first validated using simulated data from a onedimensional microwave simulator The simulated results show good precision Then the surface emissivities of the QinghaiTibet Plateau were retrieved using brightness temperatures from the advanced microwavescanning radiometer and atmospheric profile data from the moderate resolution imaging spectroradiometer Finally the features of the time and space distribution of the retrieved results were analyzed In terms of spatial characteristics a spatial distribution consistency was found between the retrieved results and surface coverage types of the QinghaiTibet Plateau In terms of time characteristics the changes in emissivity which were within 001 for every day were not evident within a onemonth time scale In addition surface emissivities are sensitive to rainfall The reasonability of the retrieved results indicates that the algorithm is feasible A timeseries surface emissivity database on the QinghaiTibet Plateau can be built using the developed algorithm and then other surface or atmospheric parameters would have high retrieval precision to support related geological research on the QinghaiTibet Plateau
