Global CO2 emissions from inland waters
Abstract
The exchange of CO2 from the surface of inland waters to the atmosphere is important globally but still uncertain. To calculate the exchange one needs to determine the surface area of inland waters, the concentration gradient of CO2 and the gas transfer velocity. Here we present on a recent RECCAP effort to systematically determine the amount of CO2 evaded from lakes, reservoirs, streams and rivers. We will present our new models, estimates and global spatial maps of the surface area, concentration gradient and gas transfer velocity. We will also discuss shortcomings and future directions.
