The right side, however, shows the real story of the danger that smoke poses. Using the OMPS (Ozone Mapping Profiler Suite) instrument aerosols are detected and measured in terms of thickness and height of the atmospheric aerosol layer. For most atmospheric events involving aerosols, the AI ranges from 0.0 (colorless through light yellow, yellow, orange, and red) to 5.0 (deep red), with 5.0 indicating heavy concentrations of aerosols that could reduce visibilities or impact health.
