Product Description
The MODerate-resolution Imaging Spectroradiometer (MODIS) Land Surface Temperature and Emissivity (LST/E) products provide per-pixel temperature and emissivity values. Averaged temperatures are extracted in Kelvin with a day/night LST algorithm applied to a pair of MODIS daytime and nighttime observations. This method yields 1 K accuracy for materials with known emissivities, and view angle information is included in each LST/E product. Emissivities in bands 20, 22, 23, 29, and 31-32 are estimates derived from applying algorithm output to database information. The LST/E algorithms use MODIS data as input, including geolocation, radiance, cloud masking, atmospheric temperature, water vapor, snow, and land cover.
The MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 5km SIN Grid product, MOD11B1, is a gridded version of the level-2 daily LST product. It is generated by projecting MOD11_L2 data to Earth locations on a Sinusoidal mapping grid in 5km pixels.
The false-colored MOD11B1 image shown was retrieved from MODIS data of April 4, 2000 over the western coast of the United States. MODIS temperature products are key inputs to many of the high level MODIS products and provide data for global temperature mapping and change observation. On land, soil and canopy temperature are among the main determinants of the rate of growth of vegetation and they govern seasonal start and termination of growth. Hydrologic processes such as evapotranspiration and snow and ice melt are highly sensitive to surface temperature fluctuation, which is also an important discriminating factor in classification of land surface types.
NOTE: These products are validated, meaning that product uncertainties are well defined over a range of representative conditions.� Although there may be later improved versions, these data are ready for use in scientific publications.
