Abstract:

This project measured NH_3 at the Blodgett Forest Research Station (BFRS) during a 3 week study in June, 2006. The site is used for ongoing air quality research and is a relatively low-background site in the foothills of the Sierra Nevada. Measured NH_3 mixing ratios were quite low ( < 1 to ~ 2 ppb ), contrasting with typical conditions in many parts of the Central Valley. Dry deposition is likely a significant loss mechanism for atmospheric NH_3 at BFRS. NH_3 is likely transported from the Valley to BFRS, but deposits on vegetation during the summer. Further work is necessary to determine whether the results obtained in this study can be generalized to other seasons.
