FY-3A IRAS OLR L1 DatasetEntry ID: FY-3A_IRAS_OLR_L1
Abstract: FY-3A_IRAS Outgoing Long-wave Radiation (OLR) L1 Dataset:
This FY-3A IRAS Outgoing Long-wave Radiation (OLR) L1 dataset describes the pre-processed product that after quality control, earth navigation and calibration from level 0 raw package data. It contains the following information: the geography latitude and longitude of the 56 pixels in one scan line, the land-sea mask, land cover and surface elevation , as well as solar zenith and azimuth angle, satellite zenith and azimuth angle, the raw digital counts and converted brightness temperature of 26 spectral channels, lab calibration coefficients of VIS-NIR channels and calibration coefficients of infrared channels of every lines, the data set also includes quality flags of the processing.
Purpose: FY-3A_IRAS Outgoing Long-wave Radiation (OLR) L1 Dataset:
The FY-3A IRAS Outgoing Long-wave Radiation (OLR) L1 dataset contains the FY-3A satellite observed brightness temperature of infrared channels located in the spectral region of from 3.7 to 15 and the visible and near-infrared spectral region of from 0.69 to 1.64. The level 1 data can be directly applied in the NWP model and satellite data assimilation research ,the climate model study, also be widely used in the atmospheric vertical sounering(such as the vertical profiles of temperature and water vapor), and cloud detection, the atmospheric component and omit longwave radiance exploration and so on.
