Abstract:

The MODIS Global Geolocation Angle files (MYDMGGAD) 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. Data Set Characteristics: Area: ~10 degrees x 10 degrees latitude/longitude Size: 1200 X 1200 rows/columns File Size: ~29 MB Resolution: 1 kilometer Projection: Sinusoidal Processing Level: 2G Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 7
