8 AHI Validation method of outgoing longwave radiation at top-of-atmosphere retrieved from Himawari-8 AHI sensor data

摘要

The present invention relates to a method for verifying upward long-wave radiation in the upper atmosphere calculated using the Himawari No. 8 AHI sensor data; The purpose of the technique is to match the temporal resolution and spatial resolution of the upper top longwave radiation (TOA OLR) of Himawari No. 8 AHI with that of the upper top longwave radiation (TOA OLR) observations of CERES, The classification data and the ground feature classification data are divided into areas and the verification procedure is performed so as to improve the accuracy of calculation of the amount of emitted radiation of the earth. Through such a verification method, the TOA OLR output (TOA OLR) of the Himawari No. 8 AHI, it is possible to easily determine the overall accuracy according to the detailed classification of the conditions, (TOA OLR), which is calculated by using AHI sensor data of Himawari No. 8 And to provide a method for verifying the parasitic wave. In order to accomplish the above object, according to a concrete means of the present invention, A top level upwing longwave radiation calculation process, a time resolution matching process, a spatial resolution matching process, a CERES sensor sky status classification process, a CERES sensor surface feature classification process, a first verification process, and a second verification process .
