MYD11C3_041

MODIS/Aqua Land Surface Temperature/Emissivity Monthly L3 Global 0.05Deg CMG V041

Version 041
  • Abstract
    The MODIS/Aqua 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 from MODIS/Aqua data acquisition date 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/Aqua V41 LST/E Monthly L3 Global CMG product (Short name: MYD11C3) is a monthly composited average, derived from the MYD11C1 daily global product, and stored as clear-sky LST values during a month’s period in a 0.05º (5600 meters) geographic CMG. MYD11C3, therefore, inherits all the structural features of its MYD11C1 parent except for the temporal configuration. Please refer to the MYD11C1 product documentation for all algorithm-related details. The V41 MYD11C3 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 Aqua/MODIS LST/E products, including MYD11C3, are validated to Stage-1 with well-defined uncertainties over a range of representative conditions. Further details regarding MODIS land product validation for the LST/E products is available from the following URL: http://landval.gsfc.nasa.gov/ProductStatus.php?ProductID=MYD11 This product is ready for use in science applications/publications. Subsequent and improved versions of this product also exist. The V41 MYD11C3 product’s acquisition range started January 1, 2007 (2007-001), and continued through February 28, 2017. 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.
