attribute	NC_GLOBAL	summary	String	From early January through mid-February 2020, NOAA is partnering with several universities and other programs to lead the Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC). The field study will take place in the tropical North Atlantic east of Barbados and investigate cloud and air-sea interaction processes with the goal of advancing understanding and prediction of U.S. weather and climate. ATOMIC is the U.S. complement to the European field campaign called EUREC4A. This collaborative effort involves a unique combination of ships, piloted and remotely-controlled aircraft, and remotely-controlled ocean vehicles to characterize ocean and atmospheric properties. A suite of instruments will be deployed from NOAA's research ship Ronald H. Brown and WP-3D Orion "Hurricane Hunter" aircraft, and on land. The focus area of ATOMIC is in the heart of the trade winds and representative of other regions across the global ocean with shallow convective clouds. Some of the Earth's largest ocean eddies (circular currents) also shed into this region from the Amazon and Orinoco Rivers. Conducting the study during winter allows researchers to observe the ocean, air, and clouds in near isolation from hurricane impacts, and to gain better insight into the ocean's involvement in making clouds that affect larger weather and climate patterns. Improved understanding of air-sea interactions in this region will help advance representations of these processes in NOAA's model forecast systems. This effort will also improve the numerical guidance used to predict weather and climate extremes.
