ELITE emissivity: global sea 0.1° CMG daily BBE (1980-2022)

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 sea BBE product at 0.1° spatial resolution and daily (at 13:00 UTC) temporal resolution. It is provided on a climate modeling grid (CMG) and ranges from 1981 to 2022 (continuously updated). This dataset was generated from the MERRA2 reanalysis wind speed data using the look-up-table method developed by Cheng et al. (2017).

Dataset Characteristics:

• Spatial Coverage: Global
• Temporal Coverage: 1980-2022
• Spatial Resolution: 0.1°
