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. 

Two new publications highlight CPO’s continued support for research in the marine ecosystem risk area. 

A newly developed climatology dataset could help construct seasonal cycles for the northern California Current system off the coast of Newport, Oregon.
