摘要: A recently developed method for large-scale monitoring of vegetation growth is the normalized difference index (NDVI) derived from reflectance data NOAA satellites. This study an investigation relationship between NDVI and rainfall in semi-arid Sahel West Africa. The temporal spatial patterns both variables are evaluated six formations region. There a strong linear if annual lies about 150 1000 mm. best correlation concurrent plus two previous months. also suggests that phenology appears to reflect soil moisture availability water-use-efficiency varies markedly among formations.
