The first soil moisture maps with a spatial resolution of one km are available online for the entire southern African subcontinent. As soil moisture plays an important role in the global water cycle, these maps, based on data from ESA’s Envisat satellite, will lead to better weather and extreme-event forecasting, such as floods and droughts.
