The InGOS / ICOS Technical Experts Workshop on non-CO2 Eddy-Covariance Greenhouse Gas Flux Measurements will be held 09.-11.06.2015, Dragør, Denmark.
Non CO2 greenhouse gas (GHG) fluxes are often small and vary substantially in space and time. As a consequence, their measurement pushes existing flux techniques, such as chamber and micrometeorological flux approaches, to the limit. To enhance the quality of services provided by the participating research infrastructures within the InGOS and ICOS networks, this workshop will bring technical experts together to discuss and document the state of the art in non-CO2 GHG flux measurements. The workshop will support the development of a measurement protocol for Non-CO2 GHG flux measurements with the eddy covariance method within the ICOS framework.
Specific topics of the workshop
- Challenges to determine non CO2-GHG concentrations: accuracy and precision, spectral response and noise, cross-sensitivities with other fluctuating gasses (H2O), fast response sensors (Topic 1)
- Eddy covariance and gradient system design, flux data processing and correction (Topic 2)
- Total uncertainty of flux estimation, flux detection limits and their main factors, flux data gap filling (Topic 3)
Venue and registration
The workshop will be held in the Dragør Badeholtel (Drogdensvej 43, 2791 Dragør Denmark, www.badehotellet.dk, E-mail: ewa@badehotellet.dk), which is very close to Copenhagen Airport. The costs include solely accommodation (2 nights), meals and use of facilities are 400 € per participant, of which InGOS will pay 100 €.
Please register by Monday, 13 April 2015 by mail to Andreas Ibrom (anib@kt.dtu.dk).
