Impact of climate variability on tropospheric ozone.
A simulation with the climate-chemistry model (CCM) E39/C is presented, which covers both the troposphere and stratosphere dynamics and chemistry during the period 1960 to 1999. Although the CCM, by its nature, is not exactly representing observed day-by-day meteorology, there is an overall model's tendency to correctly reproduce the variability pattern due to an inclusion of realistic external...
متن کاملOceanic alkyl nitrates as a natural source of tropospheric ozone
[1] Observations have revealed widespread emissions of alkyl nitrates from the tropical and Southern Oceans. We present the first chemical transport model simulations to examine the global impact of these emissions. Matching observed atmospheric abundances, we derive a total oceanic flux of methyl nitrate (MeONO2) and ethyl nitrate (EtONO2) equivalent to 0.35 Tg of N per year, which contributes...
متن کاملRole of tropospheric ozone increases in 20th-century climate change
[1] Human activities have increased tropospheric ozone, contributing to 20th-century warming. Using the spatial and temporal distribution of precursor emissions, we simulated tropospheric ozone from 1890 to 1990 using the NASA Goddard Institute for Space Studies (GISS) chemistry model. Archived three-dimensional ozone fields were then used in transient GISS climate model simulations. This enabl...
متن کاملAtmospheric Ozone and Methane in a Changing Climate
Ozone and methane are chemically active climate-forcing agents affected by climate–chemistry interactions in the atmosphere. Key chemical reactions and processes affecting ozone and methane are presented. It is shown that climate-chemistry interactions have a significant impact on the two compounds. Ozone, which is a secondary compound in the atmosphere, produced and broken down mainly in the t...
متن کاملTropospheric ozone.
Background: Tropospheric ozone is difficult to retrieve from satellites because of the abundance of ozone in the stratosphere. Tropospheric ozone has become a significant environmental issue and can be exacerbated by UT/LS folding and longrange transport events. Ozone can be moved from the stratosphere to the troposphere by upper tropospheric meteorological events. The Ozone Monitoring Instrume...
