Rain height study to predict satellite link rain attenuation

Abstract

The height of rain and the zero isotherm height serves as an important parameter to define the satellite link length in the rain volume. This enables to estimate the important rain attenuation. We introduce 5 known models of rain height and computed the zero and minus 15 °C isotherme heights in Prague. The typical height of zero isotherm in Prague (-15 °C isotherm ) varies around 3,5 km (6 km, respectively). We also compared data from seventies with 2019 data. We concluded that now the zero isotherm height is higher (global warming acknowledgement).
