Field tests were made to evaluate the accuracy/resolution relationship of the NAVAID systems (Loran/Omega) for measuring the vertical profile of the wind. Specifically, these tests involve a series of flight comparisons between the AN/FPS-16 radar and the Omega and Loran equipments. These comparisons were performed using balloon-borne radiosondes with the receiving and processing equipment located on the ground. The specific Air Force requirements are for an accuracy of 3 knots with a 2000 ft sensing interval and a fall rate of 1000 ft/min or greater. The Loran equipments were found to be capable of a 1.4 knot accuracy for these conditions, while the Omega equipments provided an accuracy of 4.3 knots. (Author).

The principal radiosonde currently being procured for both DoD and civilian agencies was recently modified by the National Weather Service to incorporate improvements in the design of the humidity duct. This design incorporated the salient features of a modification previously described by the authors. This is an interim report on a study on a study of this new radiosonde to determine the residual humidity measurement errors and to generate corrections which might further minimize these errors.
