Ventusky: Weather Forecast Maps

Map shows concentration of fine particles with a diameter of 2.5 μm or less at 10 meters above ground. Particulates are the most harmful form of air pollution due to their ability to penetrate deep into the lungs and blood streams. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires. Human activities, such as the burning of fossil fuels in vehicles, stubble burning, power plants, road dust, wet cooling towers in cooling systems and various industrial processes, also generate significant amounts of particulates. Model has lower resolution than reality. Therefore model cannot differentiate, for instance, the pollution near a highway or in a city center. Local air deterioration also occurs due to houses with stoves fueled by wood or coal. However, model is not aware about these sources.
