The Monitoring and Assessment Branch is a collection of scientists, technicians and specialists who work to minimize pollutants in the District's air. Responsibilities include:
Staff maintain and operate a 24-hour ambient air monitoring network. They calibrate scientific instruments located at several monitoring stations, collect air samples, measure pollutant concentrations, conduct studies, and report data to the United States Environmental Protection Agency.
Information is synthesized during the air quality planning process to identify and implement strategies for air quality improvement.
Air quality trends are tracked over time, and real-time air quality conditions (air quality forecasts and advisories) are provided to the public on a regular basis.
Staff conduct performance audits and program monitoring to measure how effectively the Vehicle Emissions Inspection and Maintenance Program controls pollution.
