ELITE emissivity: global land 500m daily BBE at SIN Grid (2023_001-100)

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 ELITE global land BBE product at 500m spatial resolution and 1-day temporal resolution. It is provided on a Sinusoidal grid and ranges from 2016 to 2024 (continuously updated). This dataset was generated from the Moderate Resolution Imaging Spectrometer (MODIS) data using the algorithms developed by Cheng et al. (2014; 2016).

This is the ELITE BBE product in 2023 (DOY: 001-100). Please click here to download the ELITE BBE product in 2022 (DOY: 301-365) and click here to download the ELITE BBE product in 2023 (DOY: 101-200).
