Product Description
This MODIS Land Surface Temperature and Emissivity (LST/E) monthly product is a simply composited and
averaged LST/E product of the global daily product at 0.05 degree
latitude/longitude grids (MYD11C1). 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 MYD11C3 image shown was retrieved from MODIS data during August 2003. It is an example of the MODIS Level 3 LST monthly 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.
