Radar-observed spatial and temporal rainfall variability near the Tapajós-Amazon confluence

open access: yesRevista Brasileira de Meteorologia, 2014
Standard Amazonian rainfall climatologies rely on stations preferentially located near river margins. River breeze circulations that tend to suppress afternoon rainfall near the river and enhance it inland are not typically considered when reporting ...

Drivers and impacts of sediment deposition in Amazonian floodplains

open access: yesNature Communications
The Amazon River carries enormous amounts of sediment from the Andes mountains, much of which is deposited in its floodplains. However, accurate quantification of the sediment sink at fine spatiotemporal scales is still challenging.
