The effects of whitecaps foam on the backscattering of radio waves were taken into consideration as early as 1983 in [1] and [2]. It is well known that foam and spray play an essential role in determining the dependence of altimeter wind response, especially for very high wind velocities; little effort however has been devoted so far to consider the effect of spatial foam distribution over the sea surface on the shape of the backscattered electromagnetic impulse and therefore on the measurement of Significant Wave Height and on the E/M bias of the Sea Surface Level. This work presents some results obtained by implementing a dynamic distribution algorithm for the whitecap formation and foam movement on the waves together with an altimeter simulation model.

Abstract
The effects of whitecaps foam on the backscattering of radio waves were taken into consideration as early as 1983 in [1] and [2]. It is well known that foam and spray play an essential role in determining the dependence of altimeter wind response, especially for very high wind velocities; little effort however has been devoted so far to consider the effect of spatial foam distribution over the sea surface on the shape of the backscattered electromagnetic impulse and therefore on the measurement of Significant Wave Height and on the E/M bias of the Sea Surface Level. This work presents some results obtained by implementing a dynamic distribution algorithm for the whitecap formation and foam movement on the waves together with an altimeter simulation model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
