Satellite-based Vegetation Health Index (VHI) from October 14, 2014–February 4, 2015. Scant rainfall early in the monsoon led to very stressed vegetation (dark brown) in November and early December, but hints of green (healthy vegetation) had begun to emerge in January and early February. In Malawi, brown patches near the end of the time period may be the result of inundation, not just earlier dryness. Tan areas represent average vegetation conditions. White patches are lakes and other small water bodies. Map by Dan Pisut, based on NOAA NESDIS satellite data.
