ELITE emissivity: Himawari-8/AHI daily 0.02° BBE (2020)

The Essential thermaL Infrared remoTe sEnsing (ELITE) product suite currently has four types of products, including land surface temperature (LST: clear-sky and all-sky), emissivity (NBE: narrowband emissivity; BBE: broadband emissivity; and spectral emissivity), the component of surface radiation and energy budget (SLUR: surface longwave upwelling radiation; SLDR: surface longwave downward radiation SLDR; SLNR: surface longwave net radiation), and the component of Earth’s radiation budget (OLR; outgoing longwave radiation; RSR: reflected solar radiation). The spatial-temporal resolutions of the ELITE products are mainly determined by the employed satellite data sources. For more information about ELITE products, please refer to the website (https://elite.bnu.edu.cn).

This dataset is the Himawari-8/AHI daily 0.02° BBE produced from the hourly clear-sky narrowband emissivities (NBEs) derived by the iTES algorithm (Zhou and Cheng, 2020). The bias and RMSE of the retrieved hourly NBEs are less than 0.005 and 0.014, respectively, compared with the latest MYD21 LSEs. The temporal resolution and spatial resolution of this dataset are daily and 0.02°, respectively.

This is the ELITE Himawari-8/AHI BBE product in 2020. Please click here to download the ELITE NBE product in 2019 and click here to download the ELITE BBE product in 2021.
