Statistics of Radio Refractivity Derived from Prague Radiosounding Data
MetadataAfficher la notice complète
Vertical gradient of radio refractivity in the lowest 100 m is derived from the meteorological radio-sounding data of the Prague-Libus station. The data cover the measurements at the terms 00, 06, 12, and 18UTC, and the extent of data is 20 years. Diurnal, monthly, and annual distributions are presented and the relative role of the dry and wet components of the refractivity gradient is discussed. The b0 values, expressing the percentage of the time with the refractivity gradient below -100 km-1, are presented. This work should enable the effective radio-relay link design with respect to the radiowave bending.
