This article presents an analysis of ERS-1 wind-scatterometer (WSC) data acquired over a region located in the northern Sahel. The considered period extends from January 1992 to December 1995, that is, covering four vegetation cycles. Experimental observations show that WSC responses at 45° of i...

Observations and interpretation of seasonal ERS-1 wind scatterometer data over northern Sahel (Mali)
ERS wind scatterometer (WSC) time series are analyzed over different ecoclimatic regions of the African Sahel during the period 1991–1995. At 45° incidence angle, the strong seasonality of o time series can be directly linked to the successive wet and dry seasons. Moreover, the annual o dynami...

Analysis of ERS wind scatterometer time series over Sahel (Mali)
ERS wind scatterometer (WSC) and SSNI/I data are compared for monitoring the seasonal variation of herbaceous vegetation over a sahelian region. Temporal evolution of polarization difference brightness temperatures derived from SSM/I data and WSC backscattering coefficient acquired at 45° of inci...
