Product Description
This MODIS Land Surface Temperature and Emissivity (LST/E) daily global
product (MYD11C1) provides temperature and emissivity values at 0.05 degree
latitude/longitude climate model grids (CMG). The temperature and emissivity
values are derived by reprojection and average of the values in the daily
MODIS LST/E product (MYD11B1) at 5km equal area grids in the sinusoidal
projection.
Before making reprojection in the production of MYD11C1, cloud-contaminated daytime and nighttime LSTs are removed by the double-screen scheme, which is described in paper titled "Validation of the land-surface temperature products retrieved from Terra Moderate Resolution Imaging Spectroradiometer data," by Z. Wan, Y. Zhang, Q. Zhang, and Z.-L. Li, in Remote Sens. Environ., 83, 163-180 (2002). 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 MYD11C1 image shown was retrieved from MODIS data of February 5 2004. It is an example of the MODIS Level 3 LST daily 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.
