NASA’s Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) project is a five-year project (January 2019 – December 2023) that will provide important globally-relevant data about changes in marine boundary layer cloud systems, atmospheric aerosols, and multiple feedbacks that warm or cool the climate. Marine boundary layer clouds play a critical role in Earth’s energy balance and water cycle.
ACTIVATE will study the atmosphere over the western North Atlantic Ocean and sample its broad range of aerosol, cloud, and meteorological conditions using joint flights with two aircraft based at NASA’s Langley Research Center. As an integral part of ACTIVATE, a suite of modeling tools and analysis techniques will be employed to inform preflight planning, perform data analysis, and climate model uncertainty quantification and improvement.
The deployment phase of ACTIVATE concluded in June 2022. Over three years and six deployments, ACTIVATE collected an unprecedented dataset of aerosol, cloud and meteorological parameters over the western North Atlantic. Project focus now shifts to integrated modeling and analysis studies. Past Mission News updates are available in the Mission News Archive. We invite interested researchers to access the publicly available dataset at Public Data. Introductory information and tutorials on the measurements and dataset can be found at Tutorials.
