MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 0.05Deg CMG V006

Description

The MOD11C1 Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the [MOD11C1 Version 6.1](https://doi.org/10.5067/MODIS/MOD11C1.061) data product.The MOD11C1 Version 6 product provides daily Land Surface Temperature and Emissivity (LST&E) values in a 0.05 degree (5,600 meters at the equator) latitude/longitude Climate Modeling Grid (CMG). The MOD11C1 product is directly derived from the [MOD11B1](https://doi.org/10.5067/MODIS/MOD11B1.006) product. A CMG granule follows a Geographic grid, having 7,200 columns and 3,600 rows, which represent the entire globe. Each MOD11C1 product consists of the following layers for daytime and nighttime observations: LSTs, quality control assessments, observation times, view zenith angles, number of clear-sky observations, and emissivities from bands 20, 22, 23, 29, 31, and 32 (bands 31 and 32 are daytime only) along with the percentage of land in the grid. Known Issues* Production of V6 Terra MODIS Land Surface Temperature and Emissivity (LST&E) data products was discontinued on November 16, 2022, due to [significant loss of data retrieval](https://landweb.modaps.eosdis.nasa.gov/displayissue?id=98) following the Constellation Exit Maneuvers.* For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=MODIS&sat=Terra&as=6).Improvements/Changes from Previous Versions* Removed cloud-contaminated LSTs from Level 2 and Level 3 LST products.* Updated the coefficient look-up table (LUT) for the split-window algorithm with comprehensive regression analysis of Moderate Resolution Imaging Spectroradiometer (MODIS) simulation data in bands 31 and 32 over wide ranges of surface and atmospheric conditions, especially extending the upper boundary for (LST – Ts-air) in arid and semi-arid regions. Increased the overlap between various sub-ranges to reduce the sensitivity of the algorithm to uncertainties in the input data (i.e., column water vapor and air surface temperature from MOD07).* Made minor adjustments in the classification-based surface emissivity values, especially for bare soil and rocks land cover types.* Tuned the day/night algorithm by adjusting weights to improve performance in desert regions where the incorporated split-window algorithm may not work well.* Generated new gridded LST&E products with a 6 km spatial resolution for 8-day ([MOD11B2](https://doi.org/10.5067/MODIS/MOD11B2.006)) and monthly ([MOD11B3](https://doi.org/10.5067/MODIS/MOD11B3.006)) intervals in response to user community requests.
