- The Ozone Monitoring Instrument (OMI) instrument can distinguish between aerosol types, such as smoke, dust, and sulfates, and measures cloud pressure and coverage, which provides data to derive tropospheric ozone. OMI can detect the sulfur dioxide (SO2) from volcanic plumes, which is important for volcanic plume dispersion forecasts for aviation avoidance and volcanic fog forecasts.
