During ambient air pollutants sampling, it is also necessary to collect information on qualitative and quantitative data on the local sources of air pollution, topography, population distribution, land use pattern, climatology, etc, depending upon the objectives of the survey or measurement campaign. For example, an area map to locate pollution sources and monitoring locations, sources of pollution situated at far distances, etc. and other relevant data that describe the behaviour of atmosphere for a specific pollutant to be sampled may also be required.
What it includes:
a) Selection of sampling procedures including procedures of analysis of samples
b) Sampling locations
c) Period of sampling, frequency of sampling and duration
d) Auxiliary measurements (including meteorological parameters)
e) Processing of data
