ACTIVATE: Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment


ACTIVATE is a NASA campaign spanning multiple years to characterize aerosol-cloud-meteorology interactions using  in situ and remote sensing airborne measurements with from aircraft and a hierarchy of models. ACTIVATE focuses on marine boundary layer (MBL) clouds that span the continuum of stratiform and cumulus clouds and include post-frontal conditions. ACTIVATE’s fundamental science goals:

1) Improve understanding and model representations of relationships between number concentrations of aerosol (Na), cloud condensation nuclei (CCN), and cloud droplets (Nd) and the relationships between cloud micro/macro-physical properties;

2) Acquire a unique dataset for international model intercomparison and process-based studies;

3) Evaluate current remote sensing retrievals and prototypes for future satellite missions; and

4) Develop improved satellite-based Nd retrievals and CCN proxies.

ACTIVATE acquired a statistically robust dataset through an extensive series of flights in each of four years (2019-2022) sampling a wide range of aerosol and cloud conditions.
