Effects of Possible Scan Geometries on the Accuracy of Satellite Measurements of Water Vapor

This paper evaluates the effect of scan angle on the accuracy of moisture soundings. It is found that, as the scan angle increases from nadir, the accuracy of the moisture soundings near the surface decreases because less of the surface signal reaches the satellite.
