Volatile organic compound ratios as probes of halogen atom chemistry in the Arctic

Autor: P. B. Shepson, A. E. Cavender, T. A. Biesenthal, J. W. Bottenheim

Publikováno v: Atmospheric Chemistry and Physics, Vol 8, Iss 6, Pp 1737-1750 (2008)

Volatile organic compound concentration ratios can be used as indicators of halogen chemistry that occurs during ozone depletion events in the Arctic during spring. Here we use a combination of modeling and measurements of [acetone]/[propanal] as an

During photochemical air pollution episodes in the Lower Fraser Valley (LFV) near Vancouver, BC, daytime upvalley flows carried polluted air, with high ozone (0 3 ) concentrations, into tributary valleys to the north of the LFV. Nighttime flows out o

Observations made at a ground site east of Vancouver, Canada, were used in a principal component analysis (PCA) to derive (1) the emission ratios (ER) SO 2 , NO x HNO 2 , HNO 3 , ketones, and aldehydes relative to CO and (2) the photochemical product

Observations of anthropogenic inputs of the isoprene oxidation products methyl vinyl ketone and methacrolein to the atmosphere

Autor: Paul B. Shepson, T. A. Biesenthal

Publikováno v: Geophysical Research Letters. 24:1375-1378

The isoprene atmospheric oxidation products methyl vinyl ketone (MVK) and methacrolein (MACR), along with CO, were measured in Toronto, Ontario in the winter and summer of 1996. These carbonyl compounds were highly correlated with CO in the winter, i

[1] A large set of isoprene and isoprene oxidation product concentration data from four North American sites was examined to assess the NOx dependence of the daytime oxidation of isoprene. Sites that represent a wide range of NOx (50 ppt to 30 ppb) w
