MODIS/Aqua Land Surface Temperature/Emissivity Daily L3 Global 5km SIN Grid V004Entry ID: MYD11B14
Abstract: The MODIS/Aqua V4 LST/E L3 Global 5 km Grid product (Short name: MYD11B1) incorporates 5-km pixels, which is produced using the day/night LST algorithm (Wan and Li, 1997). This algorithm 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). The data inputs include the MODIS L1B calibrated and geolocated radiances, geolocation, cloud mask, atmospheric profiles, land and snow cover.
The V4 MYD11B1 products are a gridded version of the level-2 LST product (MYD11_L2) mapped and projected on 5-kilometer (precisely 4.63 km) Sinusoidal grids. The MYD11B1 product comprises the following Science Data Set (SDS) layers for daytime and nighttime observations: LSTs, quality control assessments, observation times, view zenith angles, and emissivities from bands 20, 22, 23, 29, 31, and 32. It also includes daytime and nighttime LSTs generated from the 1-km, band 31 of the level-2 MYD11_L2 product aggregated to 5 km grids.
The V4 Aqua/MODIS LST/E products, including MYD11B1, 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 V4 MYD11B1 product has a temporal acquisition range, which starts July 4, 2002 (2002-185) until January 4, 2007 (2007-004). The V4 collection remains consistent with V41, and users may combine the two collections in a time-series analysis.
