MODIS/Terra Near Real Time (NRT) L2G Daytime Pointers, Daily 250m
The MODIS Near Real Time (NRT) Global Observation Pointers (MODPTQKM) files stores information about the spatial relationship between each sensor observation and output grid cell.MODPTQKM files are used as input to higher-level products such as MODIS Surface Reflectance. Geometric information for each sensor observation is stored on a geolocated grid with Level-2 geophysical parameters stored as Level-2G gridded products. The multiple observations stored in the L2G grids are examined by the Level-3 processes to extract only the most relevant observations per grid cell.

- Quality Overall NRT products match to operational with some expected minor differences from use of different ancillaries and ephemeris. There aren't any data gaps or data artifacts. Information on comparison of C5 Operational and NRT Atmospheric Products is posted at: http://lance.modaps.eosdis.nasa.gov/data_products/comparison.html. Information on comparison of C6 Operational and NRT Atmospheric and Land Products is posted at: http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_atmos.html and http://lance3.modaps.eosdis.nasa.gov/data_products/comparison_land.html.
