Question

Can solar flux ( Solar radio flux ) influence natural Earth radiation?

Answer 1

Assuming direct normal solar irradiance is I, then  I∗cos(θ I∗cos(θ) gives the irradiance on a tilted surface in W/m2. Integrating this over a period of time:

(J/m2)

and the same integral over dω (angle) is in Wh/m2.

Edit:

Although the unit is in Wh/m2 (Watt Hour per sq meter) but the integration is on dω(angles). This is where I am getting confused. Should it not be on dt instead?

And to get the average hourly irradiance, is it correct to divide the the above integrand(over a period of a day) by 24

Answer 2

Hey frnd☺

Here is your answer-----------------

It is an excellent indicator of overallsolar activity levels and correlates well with solar UV emissions. ... These effects are caused by impact of the increased level of solar radiation on the ionosphere. 10.7 cm solar flux could interfere with point-to-point terrestrial communications

Hope its help u
