Summary

Abstract: The MODIS/Terra Land Surface Temperature and Emissivity (LST/E) products provide per-pixel temperature and emissivity values in a sequence of swath-based to grid-based global products. The MODIS/Terra LST/E 8-Day L3 Global 0.05Deg CMG (Short name: MOD11C2) is configured on a 0.05º latitude/longitude climate modeling grid (CMG).

The MODIS/Terra version-041 (V41) products use a modified version-4 ... (V4) LST algorithm and version-5 (V5) data inputs. The V41 products primarily address underestimation problems in the V5 Climate Modeling Grid (CMG) products. Recent validation activities reveal that the V5 CMG products underestimate LSTs up to 6K especially in desert and semi-arid regions. The production date for this collection starts with MODIS/Terra data acquisition from 2007-001. This beginning date is driven by the availability of the MODIS V5 data inputs (level-1B radiance data, geolocation data, cloud mask, atmospheric profiles, and land and snow cover data).

The MODIS/Terra V41 LST/E 8-Day L3 Global CMG product (Short name: MOD11C2) is an 8-day composited average, derived from the MOD11C1 daily global product, and stored as clear-sky LST values during an 8-day period in a 0.05º (5600 meters) geographic CMG. MOD11C2, therefore, inherits all the structural features of its MOD11C1 parent except for the temporal configuration. Please refer to the MOD11C1 product documentation for all algorithm-related details.

The V41 MOD11C2 product comprises the following Science Data Set (SDS) layers for daytime and nighttime observations: LSTs, quality control assessments, observation times, view zenith angles, clear sky coverages, and emissivities for Bands 20, 22, 23, 29, 31, and 32.

The V41 Terra/MODIS LST/E products, including MOD11C2, are validated to Stage-2 with well-defined uncertainties over a range of representative conditions. Further details regarding MODIS land product validation for the LST/E products are available from the MODIS land team validation site.

The V41 MOD11C2 product’s acquisition range started January 1, 2007 (2007-001), and will continue until the V6 reprocessing completes in 2011. The V41 LST products from 2007-001 will remain consistent with similar products from V4, and hence are amenable to combine them in a time series analysis. Users should exercise caution, and not mix the V4.x (i.e., V4 and V41) and V5 LST products in their analysis.
