Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. Click to enlarge. Our study reveals that climate change and regional air pollution are intertwined problems.

Started in 2004, the AGGI reached 1.29 It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. NOAA researchers developed the AGGI in 2004 and have so far back calculated it to 1978. in 2010—i.e., Methane measured 1794 ppb in 2009, and 1714 ppb in 1990.

This summer two NASA research airplanes will fly over the Baltimore-Washington region and northeast Maryland as part of a mission to enhance the capability of satellites to measure ground-level air quality from space. Both aircraft will measure ozone and a mixture of soot and PM. DISCOVER-AQ instrumentation deployment strategy.

Scientists have long known that air over the tropics moves upward between the lower atmosphere and the stratosphere, part of a large-scale pattern known as the Brewer-Dobson circulation. This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer.

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.

The developing and least-developed economies, 80% of the world’s population, accounted for 73% of the global growth of emissions in 2004. The hole in the ozone layer has had a cooling effect on Antarctica, and is partly responsible for masking expected warming on the continent. Global emissions were growing by 1.1%
