When 1 -minute integrated rainfall rate statistics are not available for microwave system design, the conversion from rain rate cumulative distributions with a longer integration time T can be envisaged. A new set of global coefficients for the current ITU-R method of rain statistics conversion is proposed and tested against a comprehensive database. Results are compared with those provided by the currently recommended ITU-R method. Moreover, the method's applicability is extended to include 60-minute integration time conversions. Tests show that the new set of coefficients performs better than the ITU-R one over its applicability range.

Abstract
When 1 -minute integrated rainfall rate statistics are not available for microwave system design, the conversion from rain rate cumulative distributions with a longer integration time T can be envisaged. A new set of global coefficients for the current ITU-R method of rain statistics conversion is proposed and tested against a comprehensive database. Results are compared with those provided by the currently recommended ITU-R method. Moreover, the method's applicability is extended to include 60-minute integration time conversions. Tests show that the new set of coefficients performs better than the ITU-R one over its applicability range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
