The first part in the development of a new monitoring programme is often to perform a screening and evaluation of an existing measurement network. 

This part will include:

	Site evaluation including discussions of site representativeness based upon site visits
	Instruments and sensors, equipment audits, instrument sensitivity, characteristics and reliability
	Evaluate the QA/QC system operated today, including calibrations, standard operations procedures (SOP), instrument maintenance and repair
	Evaluate the data handling system, data retrieval, QC procedures and controls, and data presentations
	Evaluate personnel background and relevance, assess training needs
	Present report containing:

• Evaluation of results

• Discuss organisational set-ups

• Recommend changes, additions, sites and further studies.

The evaluation indicated above will mainly be performed to upgrade the air quality monitoring and assessment programmes. Final recommendations concerning site changes and location of new monitoring sites is being presented and reported. These recommendations may be based upon source information and meteorological data collected as input the first rough model estimates. Simple screening studies using inexpensive passive samplers may also be used to arrive at a final design of the monitoring network.

		Modify and improve existing monitoring system
		Based upon this Audit type investigation presented above, we will prepare a proposal for improving the air quality monitoring and planning system. The most important issue will be to present the first step towards a modern air quality monitoring and planning tool. Before updating the measurement network and further instruments are procured, there will be other important steps, which have to be considered in the improvement plan, such as: 1. Institutional strengthening and training 2. Improved data quality assurance (QA/QC) procedures 3. Develop systems for reporting of the data 4. Establish a new platform for the air quality monitoring and planning system 5. Investigate the interface with other networks to increase the number of monitoring sites.
