Cities have a complex mix of land uses, from commercial districts with dining and shops to residential neighborhoods linked by travel corridors, as well as industrial areas such as ports and factories. All of these different land uses lead to a diversity of urban sources that emit volatile organic compounds (VOCs) and greenhouse gasses such as carbon dioxide (CO2) and methane (CH4). Direct measurements and analysis of these species over time helps us understand human interactions with climate and air pollution.
To capture the spring release of greenhouse gasses from bog lakes, a team of intrepid UW-Madison researchers installed eddy covariance buoys on two frozen bog lakes in northern Wisconsin in March. These buoys provided under the loaner instrument program (LI-7700) by the AmeriFlux Management Project for the AmeriFlux Year of Methane are continually measuring carbon dioxide and methane fluxes and will continue doing so as ice melts and as the buoys settle into their summer home on the open water.
