Eddy covariance VOC emission and deposition fluxes above grassland using PTR-TOF
VOC grassland PTR-TOF
2011/2/24
Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution measurements (e.g. 5–20 Hz...
VOC measurements within a boreal forest during spring 2005: on the occurrence of elevated monoterpene concentrations during night time intense particle concentration events
VOC measurements boreal forest monoterpene concentrations
2009/11/19
In this study we present measurements of selected trace gases and aerosols made in a boreal forest during the BACCI-QUEST IV intensive field campaign in Hyytiälä, Finland in April 2005. Spri...
Statistical analysis of anthropogenic non-methane VOC variability at a European background location（Jungfraujoch, Switzerland）
anthropogenic non-methane VOC European background location Jungfraujoch Switzerland
2009/6/2
In-situ measurements of 7 volatile hydrocarbons, CxHy, and 3 chlorinated organic compounds, CxHyClz, were performed at Jungfraujoch (Switzerland) during eight years (2000–2007). The analysis of 4-h re...
Assessment of the reduction methods used to develop chemical schemes: building of a new chemical scheme for VOC oxidation suited to three-dimensional multiscale HOx-NOx-VOC chemistry simulations
chemical schemes VOC oxidation three-dimensional multiscale HOx-NOx-VOC chemistry simulations
2009/2/17
The objective of this work was to develop and assess an automatic procedure to generate reduced chemical schemes for the atmospheric photooxidation of volatile organic carbon (VOC) compounds. The proc...
Temperature and light dependence of the VOC emissions of Scots pine
Temperature light VOC emissions Scots pine
2009/2/8
The volatile organic compound (VOC) emission rates of Scots pine (Pinus sylvestris L.) were measured from trees growing in a natural forest environment at two locations in Finland. The observed total ...
The SOA/VOC/NOx system: an explicit model of secondary organic aerosol formation
SOA/VOC/NOx system explicit model secondary organic aerosol formation
2008/12/24
Our current understanding of secondary organic aerosol (SOA) formation is limited by our knowledge of gaseous secondary organics involved in gas/particle partitioning. The objective of this study is t...
The weekend effect within and downwind of Sacramento – Part 1: Observations of ozone, nitrogen oxides, and VOC reactivity
Sacramento ozone nitrogen oxides VOC reactivity
2008/12/23
Day-of-week patterns in human activities can be used to examine the ways in which differences in primary emissions result in changes in the rates of photochemical reactions, and the production of seco...
Technical Note: Quantitative long-term measurements of VOC concentrations by PTR-MS – measurement, calibration, and volume mixing ratio calculation methods
VOC PTR-MS volume mixing ratio
2008/11/26
Proton transfer reaction mass spectrometry (PTR-MS) is a technique for online measurements of atmospheric concentrations, or volume mixing ratios, of volatile organic compounds (VOCs). This paper giv...
Volatile Organic Compound (VOC) measurements in the Pearl River Delta (PRD) region, China
volatile organic compound pearl piver delta China
2008/11/3
We measured levels of ambient volatile organic compounds (VOCs) at seven sites in the Pearl River Delta (PRD) region of China during the Air Quality Monitoring Campaign spanning 4 October to 3 Novembe...
