MODTBGA v006

MODIS/Terra Thermal Bands Daily L2G-Lite Global 1 km SIN Grid


PI: Eric Vermote

Description

The MODTBGA Version 6 Moderate Resolution Imaging Spectroradiometer (MODIS) Level 2 Gridded Lite (L2G-lite) Thermal Band product consists of brightness temperature data from MODIS bands 20, 31, and 32 and albedo data from band 20 along with the orbit and granule pointer fields. MODTBGA is a daily product with a pixel size of 1 kilometer (km). The MODTBGA, as with other L2G data sets, stores the “best available pixel” from all the qualifying observations in the first layer and any subsequent observations are stored in either full or a compact layers within the Hierarchical Data Format (HDF) file.

Characteristics

Improvements/Changes from Previous Versions

  • New product for MODIS Version 6.

Product Maturity

The MODOCGA data product is categorized with the Surface Reflectance products and has therefore attained stage 3 validation.
