| 英文简介 | Three geostationary satellites, such come from China, Europe and U.S, could cover the whole global. Using the space borne hyper spectral instruments as the benchmark reference radiation, such as IASI and AIRS, the radiometric bias between different satellites has been corrected using the Global Space-based Inter-Calibration System. A set of multi-satellite observations data with well calibration has been generated, which could cover the main desert of the world. The sand dust aerosol optical depth (SAOD) per hour could be retrieved by the statistical approach of Infrared difference dust index and improved infrared split window retrieval method. Based on SAOD, a method of estimating the sand dust emission loading has been developed. Using this dust emission loading from satellite observation, the parameters in a model named NICAMS-SPRINTARS could be optimized. Base on the improved model simulation results and satellite observation, the global dust distribution could be displayed. Such work could promote the ability of the dust monitoring; improve our scientific understanding to global dust aerosols distribution, emission and transportation. Furthermore, this data is very useful in the radioactive forcing calculation and climate change research. |
