Air quality monitoring must satisfy certain minimum quality requirements and standards. Measurements, regardless of where and by whom they are carried out, must be comparable to those conducted elsewhere.
This is secured through a comprehensive Quality Assurance and Quality Control programme (QA/QC). QA/QC may be regarded as a chain of activities designed to deliver credible and accurate data. NILU delivers written procedures and routines for the quality control of the operation and maintenance of instruments and
programmes.
NILU also provides training of key personnel in operation, calibration and maintenance as well as undertake audits of the systems when required. The procedures developed to handle ambient air quality measurements contain several levels of controls.
In field operations will be established:
- Station Manuals including Standard Operational Procedures (SOP) for instrument installations, maintenance, controls etc.,
- Zero span checks and calibration routines.
