The data set includes: outgoing long wave radiation (OLR), surface downward long wave radiation (DLR), surface incident solar radiation (SSI), and surface upward long wave radiation (ULR). All data are from Fengyun Satellite Remote Sensing Data Service Network. Among them, satellite OLR products are widely used in the evaluation of climate model output parameters, i.e. model performance. In the Chinese meteorological community, OLR data are used to monitor the summer monsoon over the South China Sea and determine the location of the Western Pacific subtropical high. 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 general circulation models as input parameters or model performance evaluation. SSI is the solar radiation flux density incident to the earth's surface (unit: W/m2), specifically referring to the earth's surface
The total solar radiation energy received per unit time and area on the horizontal plane, including direct solar radiation and diffuse radiation. Provide input and verification for weather, climate and land surface models, and provide surface solar radiation distribution information for solar energy industry, forest and grassland fire monitoring and early warning. Satellite ULR products are used in climate models, land surface models, ocean atmospheric general circulation models, as input parameters or model performance evaluation, and also for earthquake diagnosis.
All data are stored in NC format. Taking the emitted long wave radiation as an example, the file name is "FY4A -- AGRI -- _N_DISK_SUBPO_L2-_OLR -- MULT_NOM_YYYYMMDDHHMMMSS_yyyymmddhhmmss_4000M_V0001. NC". In which, OLR represents emitted longwave radiation, NOM represents projection, yyyy represents year, mm represents month, and ddhhmmss represents specific date and time, such as FY4A-_ AGRI--_ N_ DISK_ 1330E_ L2-_ OLR-_ MULT_ GLL_ 20220601021500_ 20220601022959_ 4000M_ V0001 represents the OLR data from 2:15 on June 1, 2022 to 2:29:59 on June 1, 2022
Reading method: all files in this dataset are NC format files, which can be opened and displayed through arcgis, panoply and other software.
