3. Air Monitoring Network Requirement & Objectives
Clean Air Act Regulatory Req.
40 CFR 58.10
Siting Criteria
Operating schedules
Analysis Methods
Monitoring Objectives
Prompt Public notification

Support research studies

4. Air Pollutants & Parameters
Gaseous
Ozone (O3)
Carbon Monoxide (CO)
Standard, and Trace
Nitrogen Dioxide (NO2)
Oxides of Nitrogen (NOy)
Sulfur Dioxide (SO2)
Trace levels
Non-Methane Hydrocarbon (NMHC)
Toxics (VOCs, Carbonyls, diesel particulates)
Particulate Matter
PM10
PM2.5
Lead
Speciated
Meteorological Parameters

5. Particulate Monitoring (PM 10 & PM2.5)
PM10 or PM “Course”
<10 microns in diameter
PM 2.5 or PM “Fine”
<2.5 microns in diameter

6. BCC Particulate Air Monitoring Network (PM2.5 & PM10)

7. Particulate Monitors

8. Type I: Hourly Continuous Particulate (Real-Time Monitoring)
Beta Attenuation Monitor (BAM):
Measures PM2.5
Three Types:
Regulatory (FEM)
Non-Regulatory (non-FEM)
E-BAM (Emergency response & special studies)
Particulates are deposited on a tape
Uses radioactive beta particle absorption
Tapered Element Osculating Membrane (TEOM):
Measures PM10
Samples are deposited on a filter, that is mounted on an osculating tube.
Measurements are made by determining the decay in the osculating frequency
Aethalometer (Black Carbon)
Uses light analysis to determine composition

9. Continuous Monitor Data Collection & Public Notification
Continuous data is logged by a computer (data logger) at air monitoring site
The data logger perform initial quality assurance checks
Preliminary data are downloaded hourly and are pushed to CARB’s AQMIS
Official data is available days after sample in AQS after data validation process

10. Type II: Filter Based Particulate Monitoring

11. Types II: Filter-Based Particulate Monitoring
Federal Reference Monitors (FRM)
Measures PM10 or PM2.5
Regulatory data (i.e designations, nonattainment)
Speciated Data (CSN Network)
Operates on a EPA set schedule
Filters are analyzed by a laboratory (i.e. CARB)
Data available approx. 60 to 90 days
Monitoring Organization (MO)
Analysis
Laboratory
Uploading Agency
(CARB or MO)
EPA AQS
(Official Data)

12. Type III: Low Cost Monitors

13. Low Cost or Personal Monitors (Non-Regulatory)
Cost Range $20 to $10,000
Parameters from gaseous to particulate
Could provide information for personal exposure
Not used for Regulatory Purposes
Poor quality data obtained from unreliable sensors may lead to confusion

14. Meteorological Parameters
Surface Meteorological Data:
Wind Speed and Direction
Air Temperature at 10 meters,
Relative Humidity
Solar and Ultra Violet Radiation
Barometric Pressure
Upper Air Data, using a Doppler Radar located next to the Bruceville Air Monitoring Station
Measures Wind Speed, Wind Direction, and
Virtual Temperature up to 5 Kilometers
Provides useful information for Air Quality Forecasting & Air Quality Modeling

15. Part II:
Ag Burn Forecasting
