Guidelines for Correction of Radiosonde-Derived Refractive Profiles and Climatologies.
Abstract
Substantially more frequent occurrences of surface-based superrefractive and trapping layers have been noted in daytime than in nighttime historical refractive data derived from standard American radiosondes (military and civilian). Evidence indicates that this diurnal bias is largely or entirely fictitious. Estimates of electromagnetic propagation based on these data will be correspondingly compromised or invalidated. Several factors contribute to this bias, including sensors and sonde characteristics, exposure prior to release, and sampling and reduction procedures. This report discusses these factors, and presents recommendations both for revision of existing refractive statistics, and modifications to radiosonde observation and reduction procedures which should lead to substantial improvement in data for operational and climatological applications.
