Hi,
I have a antenna project for which I want to determine a noise temperature figure. In the reference material I have, a figure of 290 K to 300 K is given for ground noise temperature and 4 K for sky background temperature. I am interested in the gradient from a zenith angle of 75 degs to 90 degs. In other words what does the transition from ground temperature to sky temperature look like?
Has a rule of thumb been establish such a thing?
Best regards,
Fred B
