Exhaust emission rates along German inland waterways
该研究利用自下而上的方法，结合AIS数据和水道流量信息，估算了德国内河航运中CO2、NOx等污染物的排放率，并评估了现代化船队的减排潜力。
Inland navigation is a source of greenhouse gases and air pollutants. High spaciotemporal resolved vessel- and site-specific exhaust emission rates as well as accumulated total emissions of CO 2 , NO x , HC, CO and PM from German inland navigation are estimated using a bottom-up approach. The same model is applied to evaluate the mitigation potential of modernizing the current inland vessel fleet. The model pairs AIS data with daily information of flow conditions at the waterways. It accounts for driving dynamics and computes energy demand, fuel consumption and emission rates of each monitored sailing vessel. The integral over time and space yield site-specific and in a subsequent step total emission rates. Furthermore, a simulated scenario reveals the potential for emission mitigation through modernization of the existing fleet.
