Twin satellites are assessing the state of soil moisture and groundwater on the continent and around the world.
As South America moves into autumn, several parts of the continent are facing rainfall deficits and droughts that might shrink harvests. Twin satellites from NASA and the German Research Center for Geosciences are providing fresh insights into the conditions.
