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 Daily L3 Global (Short name: MOD11C1) is configured on a 0.05 degree latitude/longitude climate modeling grid (CMG).
The MODIS/Terra Collection 5 LST&E L3 Global CMG (Short name: MOD11C1) products incorporate 0.05 deg (5600 meters at the equator) pixels, which are derived from the MOD11B1 daily global 6 km grid product, and stored in a 0.05 degree 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 retrieved through the day/night algorithm. Prior to reprojecting the MOD11C1, cloud-contaminated LSTs (daytime and nighttime) are removed by a double-screening method. Further details are available in Wan et al. (2002).
The MOD11C1 products are projected in a Sinusoidal grid by mapping the level-2 LST product (MOD11_L2) on 5 or 6 km Sinusoidal grids. The MOD11C1 product comprises the following Science Data Set (SDS) layers: LSTs, quality assurance control assessments, observation times, view zenith angles, clear sky coverages, and bands 31 and 32 emissivities from land cover types.
The MODIS/Terra LST&E products, including the MOD11C1, 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 referenced under 'Val Status' section.
