Algorithm for Correcting the VHRR Imagery for Geometric Distortions Due to the Earth Curvature,Earth Rotation,and Spacecraft Roll Attitude Errors.

摘要

This report describes an algorithm for approximately correcting the Very High Resolution Radiometer (VHRR) digital data from NOAA's polar orbiting operational environmental satellites for geometric distortions that arise primarily because of the Earth's curvature and rotation and satellite roll-attitude errors. The corrections are made along each scan line independently. The algorithm is verified by an intercomparison of VHRR imagery. Several images of the Gulf Stream are included for illustration.
