MODIS/Aqua Near Real Time (NRT) Geolocation Angles Daily L2G Global 1km SIN Grid Day

NRT

The MODIS Near Real Time (NRT) Global Geolocation Angle (MODMGGAD) files contain information on solar illumination and instrument viewing geometry angles. These data can be used to model the geometric relationship and distance between the area of the Earth's surface imaged, the sun, and the sensor. This is often required to perform atmospheric corrections, or to convert or calibrate spectral data to known (absolute) radiance or reflectance units.MYDMGGAD files are used as input to higher-level products such as MODIS Surface Reflectance (MYD09). 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.

Processing Level

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.
