Landsat 8 Land Surface Temperature (LST) products are released on CASEarth Databank platform by Aerospace Information Research Institute, Chinese Academy of Sciences. LST products are generated by the AirLST retrieval procedure and the Landsat 8 images received by the remote sensing satellite ground station of China. This program utilizes the generalized single channel algorithm combined with MODIS atmospheric water vapor content product to obtain land surface temperature. For detailed information on the Landsat 8 land surface temperature product, please refer to the Landsat 8 land surface reflectance/land surface temperature product manual.

(1) Temporal coverage of the product

Basically consistent with the Landsat-8 data received and archived by remote sensing satellite ground station of China, from April 2013 to present. However, for Landsat 8 data with missing thermal infrared bands, land surface temperature inversion cannot be performed.

(2) The Landsat 8 land surface temperature product inherits all the features of the Landsat 8 ortho-rectified product, including sensors, band information, central wavelength, spatial resolution, geometric correction method, and geometric correction accuracy. Please refer to the parameter introduction of Landsat 8 on the USGS website for details.

(3) The geometric accuracy of the Landsat 8 land surface temperature product inherits the geometric accuracy of the Landsat 8 ortho-rectified product, which is consistent with the geometric accuracy of the Landsat 8 Collection 2 Level-1 data released by USGS. Radiometric accuracy of the Landsat 8 land surface temperature products was provided in detail in the Landsat 8 Land Surface Reflectance /Land Surface Temperature Product Manual
