The MODIS/Aqua L2G Daytime Pointers, Daily 250m Near Real Time (NRT) product, short name MYDPTQKM, stores information about the spatial relationship between each sensor observation and output grid cell. MYDPTQKM 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.
