Particle number concentration measured at Fairbanks, Alaska, the Alpaca Campaign (local time period : 2022/01/17 08:50 to 2022/02/26 09:51)

This is a time series of particle number concentrations measured in the ambient air of Fairbanks, downtown during the winter 2022, in the framework of the Alpaca (ALaskan Pollution And Chemical Analysis ) campaign.
The Alaskan Layered Pollution And Chemical Analysis (ALPACA) field experiment was a collaborative study designed to improve understanding of pollution sources and chemical processes during winter (cold climate and low-photochemical conditions), to investigate indoor pollution, and to study the dispersion of pollution as affected by frequent temperature inversions. An overview paper on the design, implementation, and results from the Alaskan Layered Pollution And Chemical Analysis field experiment can be found here : https://doi.org/10.1021/acsestair.3c00076.
