  abstract = {{I}n the {A}mazon basin, intense precipitation recycling across the forest significantly modifies the isotopic composition of rainfall (delta {O}-18, delta {D}). {I}n the tropical hydrologic cycle, such an effect can be identified through deuterium excess (dxs), yet it remains unclear what environmental factors control dxs, increasing the uncertainty of dxs-based paleoclimate reconstructions. {H}ere we present a 4-year record of the isotopic composition of rainfall, monitored in the northwestern {A}mazon basin. {W}e analyze the isotopic variations as a function of the air mass history, based on atmospheric back trajectory analyses, satellite observations of precipitation upstream, leaf area index, and simulated moisture recycling along the transport pathway. {W}e show that the precipitation recycling in the forest exerts a significant control on the isotopic composition of precipitation in the northwestern {A}mazon basin, especially on dxs during the dry season (r = 0.71). {A}pplying these observations to existing speleothem and pollen paleorecords, we conclude that winter precipitation increased after the mid-{H}olocene, as the expansion of the forest allowed for more moisture recycling. {T}herefore, forest effects should be considered when interpreting paleorecords of past precipitation changes.},
