Abstract
The objective of the present study is to assess the capability of the ERS-1 wind scatterometer to monitor vegetation at regional and global scales. To this end, multitemporal profiles of scatterometer data, acquired over the main vegetation types of the Africa continent, are compared to GVI data for a period extending from April 1992 to November 1993. Illustration of the effects of vegetation parameters and soil characteristics on the scatterometer response are given. Results show a good correlation between GVI and scatterometer data acquired at large incidence angles, particularly around 40 degree(s). The largest seasonal dynamic is observed over semi-arid areas like the Sahelian zone, indicating the suitability of the ERS-1 wind scatterometer for vegetation monitoring in such areas.
