                                      refer to the red message.

Ozone
Use ozone messaging grid when ozone is the primary pollutant
of concern — and particle levels are green or yellow

Particle Pollution
Use particle messaging grid when particles are the primary
pollutant of concern — and ozone levels are green or yellow.

See other side when both ozone and particles are at unhealthy
levels (orange, red. or purple)
