To fulfil the data
availability and the tools you must first set up the objectives. The objectives
of air quality data form a basis of AQ policy. The definition of the main
objectives is as follows:
To
monitor/modelling and the compliance with the limit values and national air
quality limit value. To
monitor/modelling the trends in air quality. To
provide adequate information on air quality to the public. To evaluate the effects of the emissions from traffic and energy
production (and other sources) on air quality to provide air quality data for
evaluating exposure/costs to different pollutants and their effects on health
and environment. To provide air quality data to be
used in city/land and traffic planning. The quality system should be
based on the literal regulations and working instructions and documentation of
all procedures and activities. A set of quality objectives for the measurement
results and follow up their realization. The quality of the
measurements/calculations must be based on regular maintenance and traceable
calibration/validation of the equipment/model and participation in intercalibrations/validation when possible.
Issues dedicated to modelling and
measurements (section Models for Planning: Land Use and Transport Modelling of the database) give further elements on this topic,
in particular about pollution sources, emissions and air quality models, and
traffic data monitoring. |
