Monitoring and Forecasting Air Pollution Levels by Exploiting Satellite, Ground-Based, and Synoptic Data, Elaborated with Regression Models

Figure 13

Coefficient of determination for the multiple regression model for the Ayia Marina station, for each of the prevailing synoptic conditions (1–24) and for all cases irrespective of the synoptic condition (shown as All). The synoptic conditions are ranked on the basis of the value of the coefficient of determination, from the maximum (left) to the minimum (right) value. The number given above each bar is the number of the available data pairs for the respective synoptic condition.
