 Mt. Bachelor Observatory : New paper published on carbon dioxide at Mt. Bachelor
Posted on 2016/1/15 16:10:00

Variations in carbon dioxide in the free troposphere and boundary layer observed at Mt. Bachelor are examined in a new paper by Crystal McClure and her coauthors. Published in the Atmospheric Chemistry and Physics at Mountain Sites special issue of Aerosol and Air Quality Research, the authors find that not all wildfire and pollution events correlate well with an increase in CO2 concentrations. Also, even though Mt. Bachelor experiences a steady increase in CO2 similar to other mountaintop sites (1.48 ppmv/year), the back-trajectory cluster analysis for spring shows higher ozone and lower water vapor. This is indicative of long-range, high-altitude transport.
