The MODIS/Terra Near Real Time (NRT) level-2 Land Surface Temperature and Emissivity (LST/E) data (Shortname: MOD11_L2) incorporate 1 km pixels, which are produced daily at 5-minute increments using the generalized split-window algorithm. This algorithm is optimally used to separate ranges of atmospheric column water vapor and lower boundary air surface temperatures into tractable sub-ranges. The surface emissivities in bands 31 and 32 are estimated from land cover types. The data inputs include the MODIS L1B calibrated and geolocated radiances, geolocation, cloud mask, atmospheric profiles, land and snow cover.The MOD11_L2 data set comprises swath data obtained in 5-minute sensor collection periods, and includes the following Science Data Set (SDS) layers: - LST- Quality control assessment- Error estimates- Bands 31 and 32 emissivities- Zenith angle of the pixel view- Observation time- Geographic coordinates for every five scan lines and samples. Produced daily, MOD11_L2 is an unprojected level-2 product, which provides the input for the level-3 products.
