Pristina AQM System Summary The AQM system installed in Pristina, Kosovo is described below:

One site in Pristina is collecting Continuous Particulate Matter (PM 2.5 micron) for PM at 2.5 microns and less measured in micrograms/cubic meter

The site is using two Met One Beta Attenuation Monitors (BAM), which are EPA approved FEM (Federal Equivalency Method) units according to EPA specifications. The BAM-1020 is certified Class III FEM for PM2.5 continuous monitoring (EQPM-0308-170).

The two units are side-by-side, are calibrated using the same methods and run on the same measurement principle. The primary unit reports the data, the secondary unit is used to ensure an extra layer of data reliability and validation.

Data is collected continuously for the hourly prescribed averages by a data logger on an Industrial PC platform running Envidas Ultimate air pollution capture software

The data is sent to secure server where it is then sent to the EPA Airnow website.

The EPA Airnow website will compute an Air Quality Index (AQI) value and post the data to the Airnow website

Post Staff have been trained on maintenance and operations of all equipment with remote support from WTS, LLC
