AQUATIC — Assessing and QUantifying the ATlantic Instrumental hydroClimate

          

AQUATIC addresses gaps in our understanding of tropical-and-subtropical Atlantic-sector hydrological cycle variability back to the late 19th century. We aim to characterize late-19th-to-mid-20th tropical and subtropical Atlantic sector hydrological cycle variability, to evaluate the mechanisms responsible for this variability, and to understand long-term hydrological change and constrain future climate projections.

Specific objectives:

1. Compile late-19th-to-mid-20th century (1880–1950) low-latitude Atlantic sector hydroclimate data (WP1),
2. Characterize their leading interannual-to-multidecadal variability, and examine the driving processes (WP2), and
3. Evaluate the Atlantic-sector hydroclimate responses to external climate forcings (WP3).
