Product Description
MODIS Land Surface Temperature and Emissivity (LST/E) products provide per-pixel temperature and emissivity values. Temperatures are extracted in Kelvin with a view-angle dependent algorithm applied to direct observations. This method yields 1 K accuracy for materials with known emissivities. The view angle information is included in each LST/E product. Emissivities 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 temperature products in turn 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 starting 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.
The false-colored MOD11A2 image shown above is an example of the MODIS Level 3 LST 8-day product at 1 km resolution. It is simply a composite generated by averaging 8 days of daily LST product.
