The Nature of Ozone in Deep Convective Clouds Ozone within deep convective clouds is controlled by several factors involving photochemical reactions and transport. Gas-phase photochemical reactions and heterogeneous surface chemical reactions involving ice, water particles, and aerosols inside the clouds all contribute to the distribution and net production and loss of ozone.
Improvement in modeled tropospheric ozone Tropospheric ozone is an important climate gas and an air pollutant. It plays a major role in tropospheric chemistry, such as serving as the main source for the hydroxyl radical, the atmosphere's primary oxidant.
Long-Term Global Sulfur Dioxide Pollution Monitoring From the Ozone Monitoring Instrument to the Ozone Mapping Profiler Suite : As Aura has entered the stage of extended mission and OMI has lost part of its spatial coverage due to instrument issues, it is critical to continue the global anthropogenic sulfur dioxide record with new instruments.
11.06.2017 - New NASA-funded research has devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to differentiate among three different sets of conditions that lead to its production.
11.02.2017 - Measurements from satellites this year showed the hole in Earth's ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced.
