ACCURACY OF METEOROLOGICAL DATA OBTAINED BY TRACKING THE ROBIN WITH MPS-19 RADAR

Abstract
A sample of 32 ARCAS-ROBIN rocket soundings that were tracked simultaneously by FPS-16 and MPS-19 radars was examined to determine the accuracy of meteorological data obtained from the less accurate radar, the MPS- 19. The root-mean-square error in winds determined by the MPS-19 increased with altitude in a reciprocal relationship from 5 mps at 30 km to 45 mps at 70 km; it was less than 10 mps at all levels below 55 km. No evaluation of the accuracy of thermodynamic data was possible. Any such data obtained from an MPS-19 track will be rejected under the criteria of the existing data reduction program as being from a target that failed to inflate.
