Residual Temperature-Induced Humidity Errors in the National Weather Service Radiosonde.

摘要

The principal radiosonde currently being procured for both DoD and civilian agencies was recently redesigned 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. These modifications were designed to minimize the errors in humidity measurement caused by the carbon humidity sensor having a temperature distinct from the ambient temperature. This is a final report of an in-house evaluation of the efficacy of the redesign. Results are presented on the residual errors and techniques for correcting the measured humidities to remove these residuals. (Author)
