Mapping of radio-climatological parameters and their practical utility
 Fišer, Ondřej ; Pek, Viktor ; Pitaš, Karel
Mapping of radioclimatological parameters in the form of digital or classic “paper“ maps is very useful for the planning of microwave satellite connections. Variables for simple calculation of water vapor attenuation (integrated water vapor content), clouding of cloud (integrated water content) and rainfall (precipitation intensity at 0.01%) are most often mapped. The formula for the distribution function of the attenuation is then relatively simple. Mapping is mostly done by ITU-R, ESA and WMCWF.

Vertical rain profile to estimate satellite signal attenuation
 Fišer, Ondřej ; Pek, Viktor ; Pitaš, Karel
With respect to the propagation of electromagnetic waves in frequency bands above 10 GHz, the attenuation due to the passage of electromagnetic wave hydrometers (rain, fog, snow etc.) must be respected in the design of analogue and digital satellite connections. The attenuation of the hydrometeorists depends on the length of the connection, transmission frequency, polarization and climatic conditions.
