Abstract Understanding both carbon and nitrogen temporal spatial inputs by rainfall in tropical forests is critical for proper forest conservation management might ultimately elucidate how climate change affect nutrient dynamics ecosystems. This study aimed to quantify the net precipitation contribution Atlantic Forest’s total (C) (N), identifying potential differences between these regarding (seasonal monthly) scales. Rainfall samples were collected before after interacting with canopy from May 2018 April 2019. The was enriched crossing canopy. Significant found gross annual (104.13 kg ha−1 193.18 ha−1) (16.81 36.95 inputs, respectively. Moreover, there seasonal variability C N 75% occurring wet season. Overall, patterns revealed that same locations had highest regardless of analyzed period. forest-rainfall interactions provide constant especially season, are fundamental maintenance ecological processes.
