MYD11C1_041

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

Version 041
  • Abstract
    The MODIS/Aqua V41 LST/E L3 Global CMG (Short name: MYD11C1) products incorporate 0.05º (5600 meters at the equator) pixels, which are derived from the MOD11B1 daily global 5 km grid product, and stored in a 0.05º geographic CMG. They are produced daily using the day/night LST algorithm, which extracts average temperatures (in Kelvin) and applies them to a pair of MODIS daytime and nighttime observations. This method yields 1 K accuracy for materials with known emissivities. The six thermal band emissivities are estimated through a classification-based look-up table (LUT). Prior to reprojecting the MYD11C1, cloud-contaminated LSTs (daytime and nighttime) are removed by a double-screening method. Further details are available in Wan et al. (2002). The V41 MYD11C1 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 MYD11C1, 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=MOD11 This product is ready for use in science applications/publications. Subsequent and improved versions of this product also exist. The V41 MYD11C1 product’s acquisition range started January 1, 2007 (2007-001), and continued through March 30, 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.
