Rain Absorption Temperature Calculator

calculator rain absorption temperature rf system antenna

This page provides a rain absorption temperature calculator as part of a larger suite of converters and calculators. This tool helps determine the rain absorption temperature based on the physical temperature of the antenna and the rain absorption in decibels (dB).

It’s a handy resource for anyone working with radio frequency (RF) systems, especially those dealing with signal propagation in environments with rainfall.

How to Use the Calculator

The calculator requires two inputs:

  • Rain Absorption in dB: The amount of signal attenuation caused by rain.
  • Physical Temperature of Antenna: The actual temperature of the antenna itself.

The calculator then outputs the:

  • Rain Absorption Temperature in Kelvin (K): This represents the effective noise temperature contributed by rain absorption.

Example

Let’s look at a quick example:

INPUT:

  • Rain Absorption in dB = 0.6

OUTPUT:

  • Rain Absorption Temperature in K = 37.44
