Description
The MODTBGA Version 6 data product was decommissioned on July 31, 2023.
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.

Variables
The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.
For questions on a specific variable, please use the Earthdata Forum.
