Fluxes of carbon dioxide (CO 2) and methane (CH 4) from lakes may have a large impact on
the magnitude of the terrestrial carbon sink. Traditionally lake fluxes have been measured …

Spatial heterogeneity and lake morphology affect diffusive greenhouse gas emission estimates of lakes

J Schilder, D Bastviken… - Geophysical …, 2013 - Wiley Online Library
Most estimates of diffusive flux (F) of methane (CH4) and carbon dioxide (CO2) from lakes
are based on single‐point flux chamber measurements or on piston velocity (k) modeled …

Eddy covariance flux measurements confirm extreme CH4 emissions from a Swiss hydropower reservoir and resolve their short-term variability
