Analysis of Conjunctive Rocketborne Inflatable Sphere and Bead Thermistor Soundings.

Abstract

Forty-nine conjunctive Robin/Datasonde soundings were analyzed to determine the compatibility of the temperatures and densities measured by both systems. The results of this analysis indicate differences between the two systems which at times exceed the expected noise error of either system. These large differences for any given sounding can be due to a variety of causes depending to some extent upon the altitude at which the differences occur. Additional measurements and a different Reynolds number are required to better define the sphere coefficient of drag, eliminating the bias measurement between the two systems.
