Temporal Normalization of Land Surface Temperature Derived from Ahi-8 Measurements using a Diurnal Temperature Cycle Model

Abstract

This work addresses the development of Diurnal Temperature Cycle (DTC) model and its application of temporal normalization of Land Surface Temperature (LST) derived from the measurements acquired by the Advanced Himawari Imager on Himawari-8. The results show that the DTC model can describe the LST diurnal variation with root-mean-square error (RMSE) less than 0.45 K at the four selected typical locations, and with about 90% RMSEs less than 1.0 K over the whole study area. Finally, temporally normalized LST is produced using the DTC model.
