FY-3E L1c Cloud Fraction and some results

The primary satellite microwave observation data used in this study is the L1c level dataset of FY-3E MWTS-III. For FY-3 series satellites, its preprocessing data is equivalent to L1b level data, which contains many satellite state detection parameters in addition to the observations of each channel. The MWTS-III L1c dataset is similar to the ATOVS L1c product, and it is used to support the assimilation of the MWTS-III data, in which the monitoring parameters of working state are removed, while the precipitation detection data and cloud products matched from MERSI pixels based on the MWTS-III FOVs are introduced, and the pre-processing of assimilation such as track stitching and de-duplication are completed. In this study, two kinds of data in the FY-3E MWTS-III L1c dataset are used: the brightness temperature from MWTS-III observations and the cloud fraction data matched from MERSI pixels based on the MWTS-III FOVs. The 20220904-A and 20220904-D two zip files are the lifting track data of FY-3E MWTS-III on September 4th, 2022.The Obs_clfra_gt_0_A_D_00_06_12_18.rar file is the cloud fraction of the lifting track for each time in the ten days from September 1, 2022 to September 10, 2022.The remaining two files are the probability of scattering based on cloud fraction statistics under two kinds of scattering conditions.
