Accounting for wetland greenhouse gas emissions

Methane emissions from natural wetlands account for up to a third of global methane emissions, yet they remain poorly understood in part because current measurement technology is prohibitively expensive, limited in where it can be deployed and limited in how much spatial and temporal variability it can characterize. With recalibration, low-cost natural gas sensors can provide an accurate alternative. Using this approach, the researchers aim to develop an unprecedented network of 1,000 low-cost autonomous sensors for deployment in the tropics.
