ROUTINE AIR-POLLUTION MEASUREMENTS IN ATHENS - RATIONALIZATION OF THEMONITORING NETWORK USING SPATIAL CORRELATION-ANALYSIS

In the Greater Athens Area (GAA) the air pollution monitoring network comprises 8 automatic stations, in which NO, NO2, SO2, O-3, and smoke concentrations are measured. The spatial distribution of the correlati on coefficient between the measurements of all the stations was used t o examine the representativeness of the monitoring network.
