This data set is the outgoing long-wave radiation (OLR) of FY-2C VISSR, with a time resolution of 3 hours. All data are from Fengyun Satellite Remote Sensing Data Service Network. Satellite OLR products are widely used in the evaluation of climate model output parameters, namely model performance. In the Chinese meteorological community, OLR data are used to monitor the summer monsoon in the South China Sea and determine the location of the subtropical high in the western Pacific. International OLR data are used for monitoring and analysis of ITCZ and ENSO. Satellite DLR products are applied to climate models, land surface models and ocean atmospheric circulation models as input parameters or model performance evaluation.
Data naming format: All data are stored in HDF format. Take the nominal format of 3-hour long wave radiation product as an example, and the file name is "FY2C_OLR_MLT_NOM_YYYYMMDD_HHMM. hdf". Among them, OLR represents the emitted long-wave radiation, NOM represents the projection, YYYY represents the year, MM represents the month, DD represents the day, and HHMM represents the specific time. For example, FY2C_ OLR_ MLT_ NOM_ 20090725_ 2100. hdf represents OLR data at 21:00 on July 25, 2009.
Reading method: All data in this data set are HDF format files, and common professional software such as ArcGIS and ENVI can be read.
