Zenith Angle Variation of Satellite Thermal Sounder Measurement.
Abstract
A simple procedure is presented for normalizing satellite spectral radiance measurements taken at zenith angle theta to corresponding values which would have been observed at zero zenith angle. From simulated data for the DMSP SSH sounder, it is shown that the variation of observed radiance with zenith angle is approximately linear when taken as a function of the square root of the secant of the angle. This relationship is employed to develop the correction formula. (Author)
