Determination of external and internal mixing of organic and inorganic aerosol components from hygroscopic properties of sub micrometer particles during a field study in the lower Fraser Valley
(Taylor & Francis, 2004)
A tandem differential mobility analyzer (TDMA) system was developed to measure particle growth factors over a range of relative humidities from 50-85%. This system was deployed in the Lower Fraser Valley, and data was ...
Modelling of Ozone Formation at a Rural Site in Southern Ontario
A one-dimensional time-dependent photochemical diffusion model has been used to simulate the chemical and vertical transport processes occurring at a rural location within Southern Ontario. The model output has been compared ...
Nitrogen and sulphur over the Western Atlantic Ocean
This paper reports new surface and aircraft measurements of sulphur and nitrogen species made during WATOX-85 at Lewes, Delaware and Bermuda. Concentrations of most species measured in this portion of the western Atlantic ...
Vertical column abundances and seasonal cycle of acetylene, C2H2, above the Jungfraujoch station, derived from IR solar observations
(Springer-The Netherlands, 1991)
Monthly mean total vertical column abundances of acetylene have been determined from series of infrared solar spectra recorded at the Jungfraujoch station, Switzerland, between June 1986 and April 1991. The data have been ...
A Balloon-Borne Tunable Diode Laser Absorption Spectrometer for Multispecies Trace Gas Measurements
(Optical Society of America, 1985)
A balloon-borne tunable diode laser absorption spectrometer capable of in situ measurement of the concentrations of several stratospheric trace gases simultaneously in the same parcel of air is described. Laboratory tests ...
Vertical Profiles of Ethane and Propane in the Stratosphere
Stratospheric measurements of the C2H6 mixing ratio up to 30 km and of the C3H8 mixing ratio up to 18 km altitude are reported. The observed vertical gradient of C2H6 is much weaker than that calculated from a one-dimensional ...
Measurements of Carbon Monoxide and Nonmethane Hydrocarbons During POPCORN
(Springer Netherlands, 1998)
During the field campaign POPCORN (Photo oxidant formation by plant emitted compounds and OH radicals in North-eastern Germany) in Pennewitt (Mecklenburg-Vorpommern, Germany) in August 1994, carbon monoxide and nonmethane ...
Determination of Peroxyacetylnitrate (PAN) in Unpolluted Areas
(Taylor & Francis, 1985)
Trace gas measurements during the oxidizing capacity of the tropospheric atmosphere campaign 1993 at Izana
As part of the Oxidizing Capacity of the Tropospheric Atmosphere (OCTA) project, an intensive measurement campaign was conducted in July/August 1993 at the high‐altitude observatory Izaña, Tenerife. Measurements of NO, ...
