The dynamics of moisture transport in the Amazon are key to the South American water cycle. Convection-permitting regional climate models (CPRCMs) offer a valuable tool to better understand these processes. This study evaluates integrated water vapor transport (IVT) and precipitation in the Amazon Basin using a CPRCM simulation during austral summer (DJF) and winter (JJA). Simulations at 4.5 km resolution cover most of South A...

Blue carbon ecosystems are recognized as carbon sinks and therefore for their potential for climate mitigation. While carbon stocks and burial rates have been quantified and estimated regionally and globally, there are still many knowledge gaps on carbon fluxes exchanged particularly at the interface vegetation-atmosphere. In this study we measured the atmospheric CO 2 concentrations in a salt marsh located in the Patos Lagoon...

High‐quality atmospheric CO 2 measurements are sparse in Amazonia, but can provide critical insights into the spatial and temporal variability of sources and sinks of CO 2 . In this study, we present the first 6 years (2014–2019) of continuous, high‐precision measurements of atmospheric CO 2 at the Amazon Tall Tower Observatory (ATTO, 2.1°S, 58.9°W). After subtracting the simulated background concentrations from our observatio...
