The experimental site is located in the middle of a semi-natural wetland (lake overgrown by a floating carpet of mosses) which is unique in a scale of a central Europe. POLWET is often treated as a reference site to other more degraded bogs of central Europe. The site offers complete infrastructure for Eddy Covariance measurements of CO2 and H2O fluxes (since 2004) and CH4 fluxes from 2011 (planned). POLWET site was one of the core site of CarboEurope-IP and NitroEurope-IP and will be one of the main ecosystem site within the ICOS-PL (presently in preparatory phase). Additionally, the automatic chamber measurements of CH4 and N2O fluxes are carried out since 2009 and manual chamber measurements of CH4 and CO2 fluxes since 2005 and 2007, respectively. Within POLWET infrastructure we can offer an access to fully equipped EC and weather stations, two LOSGATOS fast CH4 analysers, chambers, technical laboratory analytical tools/software and both DC and AC power supply
As the core site within the CarboEurope and NitroEurope projects, the POLWET site has offered highly qualified measurement results to the projects databases since 2004. The site have had a lot of visitors from different countries which were familiarized with EC and chamber measurements theory and techniques. Some of them initiate this measurements on their own sites. Few workshops were organized for national and international users to disseminate the knowledge and experience in GHG fluxes measurements. The site is well equipped to do some comparison studies of different GHG measurement systems.
The Rzecin scientific infrastructure was already used by scientific workers from both national and foreign institutions e.g. Adam Mickiewicz University, Poznan (Poland), Technical University of Munich (Germany), University of Bayreuth (Germany), University of Neuchâtel (Switzerland). All these scientists received a full both scientific and technical support from Meteorology Department. There is already link with Rzecin description at Meteorology Department home page however the separated Rzecin site will be developed as a source of broad information about capabilities and relevance of studies realized at this unique wetland. The Rzeicn site is the only CarboEurope station in Poland where GHG measurements are carried out in complementary mode. The development of this by involving it in the framework of InGOS project will support substantially ecological infrastructure in central Europe. The increase of users number is expected since the InGOS project will help to introduce an international standards to Rzecin site. The observations carried out on this wetland will be more relevant to other measuring sites. The obtained results will be useful for other scientists e.g. paleoecologists or ecologists for their methods development and calibrations at wetland conditions.
