Around 40 scientists will gather in Fairbanks, Alaska between 14-16 May 2018 for the first ALaskan Pollution and Chemical Analysis (ALPACA) project workshop ALPACA seeks to improve knowledge of atmospheric chemical mechanisms occurring under cold and dark conditions. These gaps are exacerbated by lack of knowledge of emissions and by wintertime meteorology, and a lack of measurements in regions with sub-freezing temperatures and low to absent photochemistry.
Improving understanding of these areas is key to delivering sound information to policy makers on protecting human health and ecosystems from harmful air pollution impacts in Arctic communities. ALPACA is being developed under PACES Working Group 2, which focuses on the interaction between Arctic air pollution and Arctic societies.
