Abstract :
Variability of sky noise temperature in the 11¿14 GHz band has been analysed using the results of radiometric observations carried out by the European Space Agency at twelve different locations for a number of years. Annual and worst-month values of sky noise temperature are presented to provide information on the variations in background noise observed by satellite earth stations.
