Greenhouse gas net emissions of rivers in Kokemäenjoki river basin. Calculated for SYKE regional compilation of GHG net emissions related to land use

The greenhouse gas (GHG) budget estimations for rivers presents the estimated CO2 equivalent for river sections and per square meter in the Kokemäenjoki watershed. Coefficients for the River GHG calculations were first derived from the Humborg et al (2013) and also used in the Luonnikas GHG calculation tool presented in the Haaspuro (2013). The result dataset is a spatial shapefile that is published as a web map service.

Results are based on utilizing existing national GIS data sets on rivers to which GHG calculation formulas and coefficients are applied according to references listed below. Dataset thus does not have an exact time span which it represents, but it is based on the aforesaid data and can be further evolved according to the new published scientific work or new, more accurate, GIS data on rivers.
