What Is “Monitoring by Citizens”?
• Citizen science• Measurements made by
– Citizens– Non-government organizations– Fixed locations or moving platforms
• Examples– Bucket Brigade (toxics monitoring)– Citizen Weather Observer Pgm.
• Technology is key– Monitor cost and size– Internet telemetry and reporting

Purpose of Presentation
• Inform about recent trends in AQ monitoring• Begin discussion about
– Understanding citizen monitoring– Evaluating implications of citizen monitoring– Determining agency interests/concerns– Creating a community of
• Public agencies• Citizens and NGOs• Private sector companies
– Establishing a Citizen Environmental Monitoring Corps?

Issues to Consider (1 of 2)
Data quality – function of application– Directional response– Response on short time scales– Long term repeatability
Representativeness– Spatial scales– Temporal scales– Mobile – sampling different environments– Indoors vs. outdoors
