Greenhouse gas emissions from reservoirs and other aquatic environments - methods and the challenge of upscaling
Abstract
The emissions of carbon dioxide (CO2) and methane (CH4) from water surfaces of reservoirs and other aquatic environments are important for assessments of net greenhouse gas (GHG) balances of landscapes. Whole-system or other large scale estimates rely on the upscaling of local measurements. Therefore the quality of the local measurements is critical for large scale assessments. While literature summaries pointing at the importance of aquatic greenhouse gas emissions get substantial attention, the fundamental methodological aspects and comparability of different local measurements are less often in focus. This presentation highlight (1) how large scale assessments of reservoir and lake GHG emissions have changed over time so far, (2) the potential impacts of methodological approaches on the large scale assessments, and (3) discuss the choice of future measurement strategies.
