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.

In winter 2022, about fifty scientists from the United States and Europe completed a seven-week atmospheric chemistry study of Fairbanks, Alaska–the state’s second-largest city. 

The study, called the Alaskan Layered Pollution and Chemical Analysis (ALPACA) project, investigated the chemistry of Fairbanks’s air pollution–especially how the pollution behaves in the cold and dark.

New publications, one on CO2 outgassing and the other on ocean-air feedbacks, contribute to the pre-field modeling studies in support of Tropical Pacific Observing System (TPOS) 2020.

Methane emissions trends for North America may be higher than reported by national inventories, primarily due to underestimation in emissions from the oil sector.
