Modeling PM2.5 Urban Pollution Using Machine Learning and Selected Meteorological Parameters

Figure 7

Data split for three different classes (see Table 6): (a) <10 μg/m3 versus 10–25 μg/m3 and (b) <10 μg/m3 versus >25 μg/m3. Both (a) and (b) are results for Cotocollao mapped in terms of wind direction, wind speed, and precipitation. The inner circle represents wind speeds up to 2 m/s and the outer circle represents wind speeds up to 4 m/s.
