Summary
Abstract: The MODIS/Aqua version-5 (V5) level-2 LST/E data (Shortname: MYD11_L2) incorporate 1-km pixels, which are produced daily at 5-minute increments using the generalized split-window algorithm. This algorithm is optimally used to separate ranges of atmospheric column water vapor and lower boundary air surface temperatures into tractable sub-ranges. The surface emissivities in Bands 31 and 32 are estimated from land cover types.

The data inputs include the MODIS L1B calibrated and geolocated radiances, geolocation, cloud mask, atmospheric profiles, land and snow cover. The V5 MYD11_L2 data set comprises swath data obtained in 5-minute sensor collection periods, and includes the following Science Data Set (SDS) layers: LST, quality control assessment, error estimates, Bands 31 and 32 emissivities, zenith angle of the pixel view, observation time, and the geographic coordinates for every five scan lines and samples. Produced daily, MYD11_L2 is an unprojected level-2 product, which provides the input for the level-3 products.

The V5 Aqua/MODIS LST/E products, including MYD11_L2, are validated to Stage-2 through field campaigns and radiance-based validation studies. 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.

The V5 collection is not consistent with V4 and V41, and users should exercise caution as they plan to use the different collections.

Description: Near real-time (NRT) data are available from MODAPS for certain Aqua and Terra MODIS L0, L1, L2, L2G, and L3 products. Whereas the standard MODIS forward processing acquires 2-hour L0 files for Aqua and Terra from EDOS within 7-8 hours of real time, LANCE-MODIS acquires session-based L0 files from EDOS and the end of the session is available within 10-30 minutes after real time.
