Ozone levels
Time series of hourly ozone concentrations, ordered by the maximum value during the last 6 hours. When ozone levels reach 155 ppb (151 IMECAS) a phase I contingency is declared. Note that the units used in the charts are ppb (parts per billion) unlike the frontpage map which uses IMECA
