Abstract : The CRPL reference atmosphere was evaluated on the basis of comparison with radiosonde data taken at both coastal and ocean weather stations in the southeastern North Pacific. Results indicate that corrections for angular aiming errors due to refraction can be made rather accurately at the ocean weather stations by use of the CRPL reference atmosphere. Selected calculations, in the form of a set of 202 figures, include seasonal trends, variation of refraction with elevation angle and height of satellite, and incidence of ducting.
