  • Hoerger et al., AMT, 2015
    ACTRIS non-methane hydrocarbon intercomparison experiment in Europe to support WMO GAW and EMEP observation networks.
    This publication summarizes the results of a large intercomparison exercise during the ACTRIS-1 project. It contains the most updated information on analysis of VOCs in ACTRIS.
  • Plass-Dülmer et al., JGR, 2006
    European hydrocarbon intercomparison experiment AMOHA part 4: Canister sampling of ambient air.
    This publication contains the main findings of the AMOHA intercomparison in 2000. Although its contents are somehow outdated, it still contains a lot of useful information.
  • Rappenglück et al., Atmos. Environ., 2006
    The first VOC intercomparison exercise within the Global Atmosphere Watch (GAW).
    This first GAW-VOC intercomparison experiment highlights the need of a network-wide calibration standard (establishing of a scale) for improving data comparability.
  • Apel et al., JGR, 2003
    Nonmethane Hydrocarbon Intercomparison Experiment (NOMHICE): Task 4, ambient air
    The NOMHICE program has been designed to evaluate current methods being used to determine the ambient levels of various atmospheric non-methane hydrocarbons, to identify existing problems in these analyses, to correct these problems and to help ensure quality control of hydrocarbon analyses made by atmospheric scientists throughout the world.

  • Apel et al., JGR, 2008
    Intercomparison of oxygenated volatile organic compound measurements at the SAPHIR atmosphere simulation chamber.
    The first large-scale in situ intercomparison of oxygenated volatile organic compound (OVOC) measurements. The intercomparison was conducted blind at the large (270 m3) simulation chamber, Simulation of Atmospheric Photochemistry in a Large Reaction Chamber (SAPHIR), in Juelich, Germany.
  • Wisthaler et al., ACP, 2008
    Intercomparison of formaldehyde measurements at the atmosphere simulation chamber SAPHIR.
