Description
A characterization of the data, including its intended use and limitations.
Abstract:
Locations of DEQ Air monitoring locations with Monitoring type and Pollutant.

DEQ's monitoring network measures the levels of five of the six ambient air criteria pollutants identified by the federal Clean Air Act. The criteria pollutants are: 

Particulate matter 
(PM10 = particulate matter less than or equal to 10 microns in diameter; PM2.5 = particulate matter less than or equal to 2.5 microns in diameter)

Carbon monoxide 
Nitrogen dioxide 
Sulfur dioxide 
Ozone 
Lead (Airborne lead is no longer considered a major health threat in most of the U.S. With the phase-out of leaded gasoline and closure of the Bunker Hill Mine, DEQ no longer monitors airborne lead levels.) 
Purpose:
The Air Pollution Monitoring program monitors all of the six criteria pollutants. Measurements are taken to assess areas where there may be a problem, and to monitor areas that already have problems. The goal of this program is to control areas where problems exist and to try to keep other areas from becoming problem air pollution areas.

pm2.5 BAM 1020 (definition not provided)
Definition Source:
The BAM-1020 monitor produces reliable, accurate, continuous, hourly results in real time. Elevated PM-2.5 events can be determined as they occur (instead of weeks after the fact), which will allow government officials to take timely mitigating action. Daily (vs. one-in-six day) PM-2.5 averages will be available and network operational costs may be substantially reduced.
PM25 Manual
Particulate Matter 2.5 Microns
PM 2.5 TEOM
Particulate Matter 2.5 Microns
Definition Source:
Federal Reference PM samplers draw a measured quantity (volume) of ambient air at a constant flow 2.5 rate through a specially designed PM particle size selective inlet. The ambient air then enters the 10 impactor that provides a nominal cut-point of 2.5 µm. Particles in the PM size range (2.5 microns in 2.5 aerodynamic diameter or less) are then collected on 47mm Teflon filter during the specified 24 hour (midnight to midnight, local standard time) sampling period. Each sample filter is weighted before and after sampling to determine the net weight (mass) of the collected PM sample. The results are 2.5 expressed as micrograms of particulate matter per cubic meter of ambient air sampled (µg/m ). The 3 monitors operate on a 3 and 6 day sampling frequency depending upon the area being sampled. The Tapered Element Oscillating Microbalance (TEOM) continuously draws in ambient air through a Teflon-coated borosilicate glass filter at a constant flow rate of 3 Liters of ambient air per minute (L/min). The PM TEOM differs from the PM TEOM by the design of the inlet and its particle size 2.5 10 separation properties. The TEOM calculates the total mass concentration of PM by weighing and 2.5 reweighing the filter every 2 seconds. The TEOM readings are smoothed exponentially to reduce noise. The final mass concentrations are expressed as micrograms of particulate matter per cubic meter of ambient air sampled (µg/m ). The TEOM is not a federal equivalent method for the measurement of 3 PM . 2.5
10M Meterological Tower (definition not provided)
Definition Source:
10M 10-meter freestanding <tower designed for small, lightweight antennas.  Aluminum MET tower is ideal for wind speed and direction equipment, sensors, and light antennas.  Tilt-base designed to be cemented directly into customer’s concrete pad.  For temporary guyed installation, tower offered with a hinged base with a temporary mounting plate, guy wire ears and a guy kit.
SO2
Sulpher Dioxide
Definition Source:
The analyzer determines the concentration of sulfur dioxide by irradiating an ambient air sample with an ultraviolet source and measuring the amount of fluorescence given off by the sulfur dioxide in the sample. The results are expressed in parts of sulfur dioxide per million parts of sampled ambient air (ppm). The monitor operates continuously.
CO Monitor
Carbon Monixide
Definition Source:
The analyzer determines the amount of carbon monoxide in a sample of ambient air by measuring the amount of infrared radiation the sample absorbs. A reference cell is filled with a non-infrared absorbing gas and a sample cell is continuously flushed with ambient air containing an unknown amount of carbon monoxide. Infrared radiation is passed through both cells. The cell contents enter a detection chamber where they are separated by a flexible membrane. The degree to which the membrane is imbalanced is proportional to the amount of infrared radiation absorbed and the concentration of carbon monoxide in the ambient air sample. A sensor detects this membrane imbalance and records the results. The results are expressed in parts of carbon monoxide per million parts of sampled ambient air (ppm). The monitor operates continuously.
PM 10 Hi Volume
PM 10 hi Volume Sampler
Definition Source:
An ambient sample of air is drawn into a sampler and pulled down over a preweighed 8" x 10" quartz filter media. After the monitor has sampled a period of 24 hours (midnight to midnight, local standard time) the filter is removed and reweighed. The concentration of suspended particulate matter is determined by dividing the weight difference by the standard volume of air sampled. The results are expressed as micrograms of total suspended particulate per cubic meter of ambient air sampled (µg/m ). The monitors are operated on an every sixth day routine.
PM 10 TEOM
Particulate Matter 10 Microns
Definition Source:
The High Volume Sampler draws a measured quantity (volume) of ambient air at a constant flow rate through a specially designed particle size selective inlet. Particles in the PM size range (10 microns in 10 aerodynamic diameter or less) are then collected on an 8" x 10" quartz filter during the specified 24 hour (midnight to midnight, local standard time) sampling period. Each sample filter is weighed before and after sampling to determine the net weight (mass) of the collected PM sample. The results are 10 expressed as micrograms of particulate matter per cubic meter of ambient air sampled (µg/m ). The 3 monitors operate on a 1, 3, and 6 day sampling frequency depending upon the area being sampled. The Tapered Element Oscillating Microbalance (TEOM) continuously draws in ambient air through a Teflon-coated borosilicate glass filter at a constant flow rate of 3 Liters of ambient air per minute (L/min). The TEOM calculates the total mass concentration of PM by weighing and reweighing the 10 filter every 2 seconds. The TEOM readings are smoothed exponentially to reduce noise. The final mass concentrations are expressed as micrograms of particulate matter per cubic meter of ambient air sampled (µg/m ). The TEOM is an EPA approved equivalent method for the measurement of PM 3 10.
Seasonal Nephelometer (definition not provided)
Definition Source:
he instrument measures the ability of particles in the air to scatter light and reduce visibility. The instrument draws an ambient air sample into a detection chamber where a flash lamp is used to illuminate the sample. The ambient sample will scatter the light into a wide range of angles. The amount of light scattered is relative to the size and concentration of particles in the ambient sample. The results are expressed in B , which can be converted to micrograms of particulate per cubic meter of ambient (scat) air sampled (µg/m ) through statistical correlation. The monitor operates continuously.
Urban Air Toxics Monitor (definition not provided)
Definition Source:
Air toxics are a group of air pollutants that are known or suspected to cause serious health problems such as cancer, birth defects, lung damage and nerve damage. Examples of air toxics include asbestos, benzene, chloroform, formadehyde, lead, mercury and nickel compounds, and perchloroethylene.

Scientists estimate that millions of tons of toxic pollutants are released into the air each year. Most air toxics originate from the following three human-made sources:

mobile (vehicles such as cars, trucks and buses); 
stationary (industrial operations such as factories, refineries and power plants); and 
indoor (chemicals in items such as some building materials and cleaning solvents). 
Some air toxics also are released from natural sources such as volcanic eruptions and forest fires.

Recent studies on air toxics have focused on releases by a variety of small sources, including cars and trucks, construction machinery, printers, auto repair shops, and numerous other small businesses that use paints or chemical cleaners. Results indicate that even though each of these activities may release only a small amount of toxic air pollution, the combined effect is significant in many cities.
PM2.5 8500 FDMS (definition not provided)
Definition Source:
The FDMS System takes into account the dynamics of PM that has been deposited on a sample collection filter, and how that material behaves over time. The device is designed to provide high-quality, representative PM mass concentration readings for both short-term averages (one hour) as well as 24-hour averages. The system’s basic output consists of running 1-hour average mass concentration (in µg/m³) of PM-10, PM-2.5 or PM-1 updated every six minutes. The unit also computes the base mass concentration and reference mass concentration over the same averaging times.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
Metadata profiles defining additonal information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
