ELITE land surface temperature: Landsat LST over CONUS (2014.1)

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 Landsat LST dataset over the CONUS generated by the radiative transfer method (Cheng et al., 2021).  Firstly, a new scheme  was used to determine the real-time Landsat 5/7/8 narrowband emissivity . Then, the MERRA2 reanalysis product was used for thermal infrared data atmospheric correction (Meng and Cheng, 2018). Finally, an LST product with 30m spatial resolution was generated using the radiative transfer equation method.

This is the ELITE Landsat LST dataset from Landsat 8 in January 2014. Please click here to download the ELITE Landsat LST from Landsat 8 in July 2014.

Essential热红外遥感（Essential thermal Infrared remote sensing, ELITE）产品套件目前包含四类产品，分别为地表温度（land surface temperature, LST：晴空与全天空）、发射率（NBE：窄带发射率；BBE：宽带发射率；光谱发射率）、地表辐射与能量收支组分（SLUR：地表长波上行辐射；SLDR：地表长波下行辐射；SLNR：地表长波净辐射）以及地球辐射收支组分（OLR：出射长波辐射；RSR：反射太阳辐射）。ELITE产品的时空分辨率主要由所采用的卫星数据源决定。如需了解ELITE产品的更多信息，请访问官网：https://elite.bnu.edu.cn。

本数据集为采用辐射传输法生成的美国本土（CONUS）范围内ELITE Landsat地表温度（LST）数据集（Cheng等，2021）。首先，通过全新方案确定实时Landsat 5/7/8窄带发射率；随后，借助MERRA2再分析产品完成热红外数据大气校正（Meng与Cheng，2018）；最终采用辐射传输方程法生成空间分辨率为30米的LST产品。
