Abstract: | 2 (1 and 24 h), SO2 (1 and 24 h), O3 (1 h) and PM10 (24 h). The AQI is linked to the new air quality guidelines in Finland. The AQI is based on acute health effects, but long-term
effects on nature and materials are also taken into consideration. Subindices are calculated hourly for all pollutants and
for a given hour the highest subindex becomes the AQI. AQI values are currently calculated for the center of Helsinki and
for typical suburban areas. |
