An evaluation of ARM radiosonde operational performance
Because the ARM (Atmospheric Radiation Measurement) program uses data from radiosondes for real-time quality control and sensitive modeling applications, it is important to have a quantitative measure of the quality of the radiosonde data themselves. Two methods have been tried for estimating the quality of radiosonde data: comparisons with known standards before launch and examination of pseudo-replicate samples by single sensors aloft. The ground check procedure showed that the ARM radiosondes are within manufacturer`s specifications for measuring relative humidity; procedural artifacts prevented verification for temperature. Pseudo-replicates from ascent and descent suggest that the temperature measurement is within the specified {minus_plus}0.2 C. On average ascent and descent data are similar, but detailed structure may be obscured on descent by loss of sampling density, and the descent involves other uncertainties.
