In most of the literature, accuracies for radiosonde-measured atmospheric moisture are expressed in terms of relative humidity, i.e., the percent of saturation. The report presents the radiosonde-measured atmospheric moisture accuracies in terms of dew point, i.e., saturation temperature. The dew-point root-mean-square RMS errors are presented in tables which resulted from the computations and in nomograms for ready use. A table and a nomogram are included for temperatures between 0C and 40C, and another of each for temperatures between -40C and 0C. Dew-point accuracies are least for high temperatures and low dew points and greatest for low temperatures and high dew points in each temperature group, viz., 0C to 40C and -40C to 0C.
