Product Description
This MODIS Land Surface Temperature and Emissivity (LST/E) product is a
simply composited and averaged LST/E product of the global daily product at 0.05 degree
latitude/longitude grids (MYD11C1) over a period of 8 days. 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 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.
The false-colored MYD11C2 image shown above was retrieved from MODIS data between February 10-17, 2004. It is an example of the MODIS Level 3 LST 8-Day product at 0.05 degree resolution.
NOTE: This product is still experimental in nature upon its initial release. More investigations are underway to assess the scientific quality.
