Radiation of the Earth in VHF band

[Jugger]

How much is the power of radiation in the VHF 30-300 MHz range of the Earth, for example W / sq.m. at a certain distance from it or square meters surface ?
At least some

Interest because it is this range of passes through the ionosphere and goes into space, I wonder how much radiation the Earth in space

 

[Jugger]

More precisely 30 MHz - 3 THz
Because I understand the waves with a frequency greater than 30 MHz go into space, and radio band ends at 3 THz

What about the power of the transmitters are placed on satellites?
I understand in this range includes mobile phones, satellite television and radio, so you can at least roughly estimate the radiation power of the Earth

What other vehicle emits a lot in this range?

 

[Tweekerbob]

Most frequencies above 30MHz at any given time, do pass through the ionosphere. How far they travel into space is dependent on several factors: radiation angle, power, obstabcles, etc. Planning on space travel anytime soon to see if you still get cell coverage?
Isn't W/m^2 usually reserved for solar radiation? I think it would be a bit trite to try and measure any RF (man-made) field this way.

The earth has a noise temperature of around 290K and at microwave frequencies you can really see the noise floor rise when pointing an antenna from free space down to the ground.

At VHF/UHF man made noise will probably dominate over earth noise, especially in urban areas.
