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

The <strong>E</strong>ssential therma<strong>L</strong> <strong>I</strong>nfrared remo<strong>T</strong>e s<strong>E</strong>nsing (<strong>ELITE</strong>) 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° NBE produced from the hourly clear-sky NBE dataset derived by the iTES algorithm (Zhou and Cheng, 2020). The bias and RMSE of the retrieved hourly NBE are less than 0.005 and 0.014, respectively, compared with the latest MYD21 LSE. The temporal resolution and spatial resolution of this dataset are daily and 0.02°, respectively. This is the ELITE Himawari-8/AHI NBE product in 2020.
