Chamber flux (CH4 , CO2), temperature, water table and vegetaion data from Särkkä (62° 48'; 30° 58') and Lakkasuo (61° 47'; 24°16') from Finland (1991 -1993). These are natural and drained site data few decades after drainage nearby each other. This data was originally used in following articles: Chamber measuremets CH4, CO2 Martikainen P.J., Nykänen H., Alm J. and Silvola J. 1995.
