Aura Science : Data and Images : OMI

	OMI sees BrO enhancements over the North Pole OMI, with its wide swath, is the only instrument that can detect Bromine Monoxide (BrO) at the pole on every orbit. Here, stratospheric BrO has been carefully separated from the total column to produce estimates of the tropospheric BrO column.
	Direct observations of megacity emissions and lifetimes of nitrogen oxides using OMI Emission inventories in megacities are uncertain, particularly in developing countries. Can we use OMI to better quantify these emissions without a model?
	Decrease in SO₂ over the Eastern US OMI data confirm a substantial reduction in sulfur dioxide (SO₂ ) values around the largest US coal power plants as a result of the implementation of pollution control measures.
	Global satellite analysis of the relation between aerosols and short-lived trace gases Information on the global composition of aerosol particles, their emission sources and relative regional pollution controls of combustion processes.
	A-Train data for Merapi volcanic cloud Indonesia's Mount Merapi turned destructive, unleashing a series of eruptions.
	Pollution episode over China Aura observes a high-pressure weather system settled in over eastern China, in which air pollution began to accumulate locally for nearly a week.
	Eyjafjallajskull volcano Near-real-time OMI images of ash and sulfur dioxide from Icelandic eruption
	Aura OMI observes reduction of Sulfur dioxide pollution over China Chinese sulfur dioxide (SO₂) emission controls were given a major strengthening in the 11th Five-Year-Plan.
	Air Pollution Controls Air Pollution Controls for Summer Surface Ozone as Deduced by OMI
	Air Quality Changes Resulting from Emission Regulations Regulations have resulted in reduced NOx emissions from major point sources over much of the Eastern US as shown by OMI's Continuous Emission Monitoring System data.
	Aura and CALIPSO Combined use of A-train data for improved aerosol characterization
	Aura and CloudSat Combined use of A-train data for improved cloud study
	South American biomass burning OMI observes large decrease of South American biomass burning in 2008
	Nitrogen dioxide trends OMI NO2 trends: 2007 - 2005 annual means
	OMI Observes Impact from the Gulf Hurricanes Hurricanes Katrina and Rita caused a significant reduction in nitrogen dioxide emissions.
	Nitrogen Dioxide Observations in California Aggressive air quality regulations of emission reductions show results in Aura's OMI imagery.
	Sarychev Peak Eruption The eruption of Sarychev Peak (Kurile Islands) in mid-June 2009 produced a large stratospheric sulfur dioxide cloud that spread rapidly eastward in strong jet stream winds.

	NO2 in the Troposphere View collection of movies created from Aura's OMI instrument of NO2 in the troposphere.
	Fires In Southern California NASA satellites continue to capture remarkable new images of the wildfires raging in Southern California. Aura's OMI images show the smoke aerosol layer generated by the fires in Southern California as it drifts over the Pacific Ocean.

	California fires as seen from MODIS and OMI Smoke from the recent outbreak of fires in Southern California can clearly be seen via NASA satellites.
	Aleutians Eruption OMI captured the SO2 cloud in 2 consecutive orbits of the eruption in the Aleutians.
	Air Quality during the Olympics Restrictions were put on traffic and power plants to improve air quality in Beijing during the Olympics. OMI makes daily measurements of the total column of SO₂ and NO₂.
	Okmok eruption Sulfur dioxide measurements from the Ozone Monitoring Instrument (OMI) on Aura permitted tracking of the eruption cloud in near real-time.
	Springtime OMI Measurements of BrO Despite its low atmospheric abundance, bromine monoxide (BrO) plays an important role in the chemistry of the atmosphere because it is a catalyst of the ozone destruction.
