Evaluation of low-cost, tree-mounted temperature loggers for validation of satellite-based flood mapping on the Amazon floodplain.
The spatial extent, duration, and depth of inundation are key factors in the functioning of floodplain ecosystems. Satellite-based methods have been developed for mapping flooding extent and water surface height across large floodplain reaches, but on the Amazon floodplain, ground measurements for r...
