MODIS/Terra Geolocation Fields 5-Min L1A Swath 1km V005

Version 5 eng
  • Abstract
    The geolocation fields are calculated for each 1 km MODIS Instantaneous Field of Views (IFOV) for all orbits daily. The locations and ancillary information corresponds to the intersection of the centers of each IFOV from 10 detectors in an ideal 1 km band on the Earth's surface. A digital terrain model is used to model the Earth's surface. The main inputs are the spacecraft attitude and orbit, the instrument telemetry and the digital elevation model. The geolocation fields include geodetic Latitude, Longitude, surface height above geoid, solar zenith and azimuth angles, satellite zenith and azimuth angles, and a land/sea mask for each 1 km sample. Additional information is included in the header to enable the calculation of the approximate location of the center of the detectors of any of the 36 MODIS bands. This product is used as input by a large number of subsequent MODIS products, particularly the products produced by the Land team. (The shortname for this product is MOD03). The V004 Program Executable (PGE), for MODIS Level 1B products, has gone through a series of revisions since the initial release of V4.0.0 in March of 2002. These include revisions to make it LINUX-compatible. The current version is V4.0.9, which does not contain changes to the code that affect scientific output. Below is a brief overview of changes that affect scientific output in previous versions (V4.0.0 to V4.0.7) of PGE code. The MCST web site, listed in the URL section of this DIF, has a more detailed version of this information, including revisions that do not affect scientific output. Significant changes to Look Up Tables (LUT) used in Level 1B processing have occurred. These include revising the Response-versus-Scan Angle (RVS) LUTs from listing the RVS corrections to listing the quadratic coefficients used in making the RVS correction. The coefficients are now calculated by interpolating on the granule collection time and the RVS corrections are then generated using the interpolated coefficients. Previously used Emissive and Reflective RVS LUT tables were eliminated and new ones introduced.
