Abstract
Atmospheric profiles of pressure, temperature, and relative humidity, measured with stratospheric balloons, are used to calculate the radiof requency brightness temperature, T-atm, of the atmospheric signal seen by a ground observer. Below 1 GHz the calculated values are definitel y more precise(few percent accuracy), than directly measured values( 1 0% accuracy or worse).
