The projectís aim was to improve the fundamental understanding of biosphere-atmosphere interactions based on available long-term field observations and process studies. The project used the field data from Finnish and Chinese agriculture, lake and wetland measurement sites and international databases together with theoretical process modelling.
The broader significance of the findings: ICOS (Integrated Carbon Observation System) is developing protocols for standardised measurements of fluxes. The intercomparisons of methdos done brought valuable information on the performance and capabilities of the measurement techniques. The methane model developed in the project is utilised in the context of estimating larger scale sink and sources. The long-term flux records on lakes are still scarce and the project established two long-term lake sites. The chamber-based estimate for agricultural nitrous oxide emissions were very close to the default value recommended by IPCC.
