Air quality monitoring network in KosovoBased on criteria for determination of monitoring location, according to directive 2008/50/EC,It’s decided that air quality monitoring network in Kosovo will have 12 fixed stations and 1 Mobile station. Locations and stations’ type are shown in map fig.1 and tab.1

Collecting, processing and validation data
Data from different types of stations procesed and validated in diferent softwares, depending on analyzers’ producing factory,see pictures belowe.

Collected and processed data from three different softwares are transferred in one software (application) which does data statistical analyzes. Software is designed by the assistance of Finish experts during implementation of Twining Project last year.
Statistical analyze and data validation
(Application) where datas are transferred from all monitoring system
EMMA Software for collecting,processing, and validation data from AQ monitoring system
During this year a project which will install server for storing and collecting data from all stations has been implemented.In this server Software EMMA is configured .See fig,x belowe.
This software posseses one interface where the public will have access.Public can see the current data and export it.See fig.x belowe
QA/QC of air quality datas We have to trace the data every day, because equipment malfunction, human
error, power failures and other disturbances can result incorrect data, these must be filtered out.
Raw data is always kept unchanged, and reports of the edits made to the raw data are saved
AQ data is corrected according to calibrations, this has to be done as soon as
possible after the calibration.
Continuous AQ data examination from hourly line chart, both daily data summaries and longer periods gives information about the slide of the zero level or the amplification of the analyser that will be noticed only from long time serie charts
Continuous review of zero and span checks - inform field operators of any equipment malfunction or problem requiring
attention
Can be incorrect values but need to be investigated reasons belowe before removal:-Information from nearby industry, e.g. emission disturbance at the same time?-Effects of meteorology (e.g. wind direction? )-Effect of power failure?-Levels of other pollutants (e.g. O3 vs. NOx)-Time of day/year-Observations from other sites (visual comparison to AQ data from other measurement stations in the same figure)
Proper calibration of automatic monitors is essential for obtaining accurate AQ data.
For each calibration a correction factor (CF) and zero correction (ZC) is calculated.
Through this formula we calculate the corrected value:Corrected value = CF(uncorrected value-ZC)Both CF and ZC change linearly from “start” calibration to “end” calibration .
Thanks for your attention
