Our analysis indicated that there were some deviations in the radiance in the MERSI-2 TIR bands, so we built a cross-calibration model. ...
Thus, we propose a method for retrieving LST by using the SW algorithm after cross-calibration of the BT from MERSI-2 TIR bands (Bands 24/25) with that from MODIS TIR bands (Bands 31/32) as the reference ...

The thermal infrared (TIR) data from the Medium Resolution Spectral Imager II (MERSI-2) on the Chinese meteorological satellite FY-3D have high spatiotemporal resolution. ...
Sensitivity analysis shows that the SW algorithm is not sensitive to the two main parameters (WVC and emissivity), which also proves that the estimation of LST from MERSI-2 data is feasible. ...
