This fact sheet summarizes NOAA’s efforts to improve the understanding of the impact of aerosols on weather, air quality and climate.

CHEESEHEAD19 Field Campaign produces useful criteria for using a variety of ground-based remote sensing instruments used to measure planetary boundary layer height.

Expanded record of air-sea CO2 fluxes created using machine learning techniques improves our ability to model annual changes in the ocean carbon sink.

Increased evaporative demand will be an essential consideration for land and water management planning going forward.

New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.
