West Africa Drylands Project | Introduction | Vegetation remote sensing

>>

This initial screening study of Sahelian climate and vegetation is based on rainfall data going back to 1931 and vegetation data from satellites going back to 1981. Like many other studies this work uses low resolution (8x8 km blocks) global vegetation data with one data value per 10 day (dekad). Vegetation is expressed as NDVI (Normalised Difference Vegetation Index) that is used as a proxy for vegetation cover and absorption of photosynthetic active radiation.
