Determining the exchange of greenhouse gas between the landscape and the atmosphere is a challenge. Several measurement methods and trace gas detectors exist to measure the exchange fluxes of carbon dioxide, methane and nitrous oxide. Different source systems e.g. pasture, arable lands, ditches, forest require a combination of several techniques and detectors. This paper provides an overview of the techniques used in the BSIKClimate Changes Spatial Planning projects. Chamber measurements, micro meteorological measurements, plume measurements and tall tower verification measurements and the role of these in the BSIK programme are described. The results of the measurements are discussed in the subsequent papers in this special issue. The paper advocates simultaneous use of different techniques to evaluate trace gas exchange. A combination of techniques can better constrain the emission levels from relevant sources. The paper also promotes the use of measurements as the primary source of information on the status of the contribution of our landscape to the balance of greenhouse gasses. |
