Observations of NOx, ΣPNs, ΣANs, and HNO3 at a rural site in the California Sierra Nevada Mountains: summertime diurnal cycles (2009)

D. A. Day, D. K. Farmer, A. H. Goldstein, P. J. Wooldridge, C. Minejima, R. C. Cohen

Observations of NO, NO2, total peroxy nitrates (ΣPNs), total alkyl nitrates (ΣANs), HNO3, CO, O3, and meteorological parameters were obtained from October 2000 through February 2002 at...

Cloud condensation nuclei in pristine tropical rainforest air of Amazonia: size-resolved measurements and modeling of atmospheric aerosol composition and CCN activity (2009)

S. S. Gunthe, S. M. King, D. Rose, Q. Chen, P. Roldin, D. K. Farmer, ...

Atmospheric aerosol particles serving as cloud condensation nuclei (CCN) are key elements of the hydrological cycle and climate. We have measured and characterized CCN at water vapor supersaturations...

Observations of HNO3, ΣAN, ΣPN and NO2 fluxes: evidence for rapid HOx chemistry within a pine forest canopy (2008)

D. K. Farmer, R. C. Cohen

Measurements of exchange of reactive nitrogen oxides between the atmosphere and a ponderosa pine forest in the Sierra Nevada Mountains are reported. During winter, we observe upward fluxes of NO2,...

Application of thermal-dissociation laser induced fluorescence (TD-LIF) to measurement of HNO3, Σalkyl nitrates, Σperoxy nitrates, and NO2 fluxes using eddy covariance (2006)

D. K. Farmer, P. J. Wooldridge, R. C. Cohen

Nitrogen exchange between the atmosphere and biosphere directly influences atmospheric composition. While much is known about mechanisms of NO and N2O emissions, instrumentation for the study of...
