New systems to compile emission data in urban areas
CitizenObservatories - Use of FCD and microsensors

9. GEIA Urban Working Group Exchange of experiences and best practices
Understanding emissions in urban areas requires a combination of measurements and emission process modelling
Evaluating the efficiency of control measures requires good information on emission processes
Make use of new measurement methods (PEMS, FCD, flux meaurements…)
Database for emission meaurements - Global extension of HBEFA ?
