Background

About the Data System (Purposes, Audience):

The HEI Air Quality Database focuses on levels of PM2.5 components and gaseous pollutants at and near sites in the EPA's PM2.5 Chemical Speciation Trends Network (STN) and State, Local and Tribal air monitoring stations (SLAMS). The Database was originally made available in association with HEI's Request for Applications 05-1, Studies to Compare Components and Characteristics of Particulate Matter Associated with Health Effects, which was issued in the summer of 2005. The Database is now available to investigators interested in using the information for studies on air quality and health. Currently, the Database contains information on speciated PM components and gaseous pollutants at these sites for the years 2000-2006 and it is anticipated that the information will be updated regularly for the next 2-3 years.

History:

The HEI Air Quality Database was originally made available in association with HEI's Request for Applications 05-1, Studies to Compare Components and Characteristics of Particulate Matter Associated with Health Effects, which was issued in the summer of 2005. Since then, the database continues to evolve in response to requests from the health community, for example, data on PM elements and carbon blanks have been made available. The database is updated approximately every six months using the most current data from the Air Quality System and other source databases.

Data System Scope

Data Content

---

Datasets Served:

• Meta data associated with STN core + supplemental sites:

1. State, County, Site ID
2. Latitude/longitude
3. Metropolitan area
4. Population (census)
5. Local emissions (National emissions inventory)
6. Land use/setting/monitoring objective

• Concentrations and meteorology from AQS:

1. PM2.5 mass, elements, ions, OC/EC (STN network)
2. Gases (subset of monitoring sites near STN sites): Ozone, CO, SO2, NO2, NOx (processed into daily maximum one-hour concentration, daily maximum 8-hour average concentration, or 24-hour average concentration) (SLAMS/NAMS/PAMS network)
3. Meteorology: temperature, RH, wind speed (processed into daily maximum one-hour value, daily maximum 8-hour average value, or 24-hour average value), wind direction (direction associated with maximum one-hour wind speed or most frequent compass direction in the 24-hour period)

• Meteorology from NCDC

1. temperature, dew point, visibility wind speed (processed into daily maximum one-hour value, daily maximum 8-hour average value, or 24-hour average value), wind direction (direction associated with maximum one-hour wind speed or most frequent compass direction in the 24-hour period)
