8 AHI Retrieval method of Top-of-atmosphere Reflected Shortwave Radiation using Himawari-8 AHI sensor

摘要

The present invention relates to a method of calculating reflected shortwave radiation of top of atmosphere using a HIMAWARI-8 AHI sensor. The purpose of the present invention is to provide a method of calculating reflected shortwave radiation using a HIMAWARI-8 AHI sensor which is a geostationary orbiting weather satellite operated by the Japan Meteorological Agency. The method of calculating reflected shortwave radiation using a HIMAWARI-8 AHI sensor can increase a time-space resolution for the Korean peninsula weather observation by a reflected shortwave radiation (RSR) calculation algorithm using the HIMAWARI-8 AHI sensor operated on July 2015 to generate higher quality input data than the index forecast model, and can be variously used for solar radiation and earth radiation energy, weather forecast, weather science, atmospheric chemistry, and a surface property related study by easily generating highly accurate various forecast ancillary data. Therefore, the method of calculating reflected shortwave radiation using a HIMAWARI-8 AHI sensor comprises a step of calculating band radiance, a step of calculating band reflectance, a step of estimating band flexibility, a step of estimating an angular distribution model, a step of calculating band albedo of top of atmosphere, and a step of calculating RSR.
