Data From Limited Monitoring Sites

Because data from only a limited number of monitoring stations are used to create these animations, the viewer should use caution when interpreting the images. Although it may appear that a certain ozone level is found only around a monitoring site, that same ozone concentration may also be found in other areas where no ozone monitoring data is available, but it does not appear on the animation. The program also assumes a certain background level of ozone is found across the area even though higher or lower levels of ozone may exist in areas with no monitors.

Ozone animation images are available starting June 29, 2008 12:00 PDT.

The individual frames of the ozone animation are 400x400 pixels. New image frames are generated once an hour. There are 3 frames produced per hour; thus, for 24 hours of animation time, 72 individual image frames would be included.

Key to animation colors:

Ozone levels in this range are considered healthy.
  • No health impacts are expected when levels are within this range.
Ozone levels in this range are considered moderate.
  • Unusually sensitive individuals may experience respiratory symptoms.
Ozone levels in this range are projected to be unhealthy for sensitive groups.
  • Increasing likelihood of respiratory symptoms and breathing discomfort in active children and adults and people with respiratory disease, such as asthma.
Ozone levels in this range are projected to be unhealthy.
  • Greater likelihood of respiratory symptoms and breathing difficulty in active children and adults and people with respiratory disease, such as asthma; possible respiratory effects in general population.
Ozone levels in this range are projected to be very unhealthy.
  • Increasingly severe symptoms and impaired breathing likely in active children and adults and people with respiratory disease, such as asthma; increasing likelihood of respiratory effects in general population.
