    INTRODUCTION

    Correct navigation of airborne weather radar data with respect to the earth is a critical aspect of producing correct and usable data. In order to meet the scientific requirements concerning data location and to correct radial velocities for aircraft motion, the aircraft trajectory and velocity and the radar beam pointing angles must be known with great accuracy with respect to the ground..

    The corrections listed below were calculated using methodology defined in the paper entitled: A Procedure To Correct Airborne Doppler Radar Data For Navigation Errors, Using The Echo Returned From the Earth Surface (Testud, et al)

    Please see the Data Processing Overview section of the User Guide for further details on how to apply the corrections to the data.
