Effects of ionosphere and troposphere on sensitive radio observations from 70 MHz to 24 GHz

Any electromagnetic signal coming from outside the Earth's atmosphere will get affected by the Ionosphere at centimeter and meter wavelengths while the same will get affected by the Troposphere between centimeter and millimeter wavelengths. In this work, we explore a uniform formalism to understand the highest radio frequencies where ionosphere poses a challenge for sensitive radio observations with upcoming telescopes like the SKA (Square Kilometer Array). We also investigate the lowest radio frequencies where Tropospheric effects are still significant for SKA-like observing capabilities.
