MODIS/Terra Land Surface Temperature/Emissivity Monthly L3 Global 6km SIN Grid V006

Description

The MOD11B3 Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the [MOD11B3 Version 6.1](https://doi.org/10.5067/MODIS/MOD11B3.061) data product. The MOD11B3 Version 6 product provides average monthly per pixel Land Surface Temperature and Emissivity (LST&E) in a 1,200 by 1,200 kilometer (km) tile with a pixel size of 5,600 meters (m). Each LST&E pixel value in the MOD11B3 is a simple average of all the corresponding values from the [MOD11B1](https://doi.org/10.5067/MODIS/MOD11B1.006) collected during the month period. Each MOD11B3 granule consists of 19 layers including daytime and nighttime layers for LSTs, quality control assessments, observation times, view zenith angles, and number of clear sky observations along with percentage of land in the tile and emissivities from bands 20, 22, 23, 29, 31, and 32. Unique to the MOD11B products are additional day and night LST layers generated from band 31 of the corresponding 1 km [MOD11_L2](https://doi.org/10.5067/MODIS/MOD11_L2.006) swath product aggregated to the 6 km 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) intervals in response to user community requests.
