Abstract. We use a regional chemistry transport model (Weather Research and Forecasting coupled with chemistry, WRF-Chem) in conjunction surface observations of tropospheric ozone Ozone Monitoring Instrument (OMI) satellite retrievals column NO2 to evaluate processes controlling the distribution over western Siberia for late spring summer 2011. This region hosts range anthropogenic natural prec...

Abstract. Nitrogen oxides (NOx?NO+NO2) in the NOx-limited upper troposphere (UT) are long-lived and so have a large influence on oxidizing capacity of formation greenhouse gas ozone. Models misrepresent NOx UT, observations to address deficiencies models sparse. Here we obtain year near-global seasonal mean mixing ratios NO2 UT (450–180 hPa) at 1?×1? by applying cloud-slicing partial columns fr...

Ground-based lidars are suitable for long-term ozone monitoring as a complement to satellite and ozonesonde measurements. However, current ground-based lidars are unable to consistently measure ozone below 500 m above ground level (AGL) due to both engineering issues and high retrieval sensitivity to various measurement errors. In this paper, we present our instrument design, retrieval techniqu...

The Gas Absorption Spectrometer Correlating Optical Difference—New Generation 4 (GASCOD/NG4) is a multi-axis differential optical absorption spectroscopy (MAX-DOAS) instrument which measures diffuse solar spectra at the Environmental-Climate Observatory (ECO) of Italian research institute CNR-ISAC, near Lecce. high-resolution measured in zenith-sky configuration were used to retrieve NO2 and O3...

Atmospheric ozone plays an important role in the biosphere’s absorbing of dangerous solar UV radiation and its contributions to Earth’s climate. Nowadays, variations are widely monitored by different local remote sensing methods. Satellite methods can provide data on global distribution anomalies. In contrast measurement techniques based measurements, Fourier-transform infrared (FTIR) satellite...

The ground-based ozone observation instrument, Brewer spectrophotometer (Brewer), was used to evaluate the quality of total column (TOC) produced by multiple polar-orbit satellite measurements at three stations in Antarctica (King Sejong, Jang Bogo, and Zhongshan stations). While all TOCs showed high correlations with (R = ~0.8 0.9), there are some TOC differences among data austral spring, whi...

MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) is operating on the ENVIronmental SATellite (ENVISAT) since March 2002. After two years of nearly continuous limb scanning measurements, at the end of March 2004, the instrument was stopped due to problems with the mirror drive of the interferometer. Operations with reduced maximum path difference, corresponding to both a reduced...

Abstract. In recent years, satellite remote sensing has been increasingly used in the long-term observation of ozone (O3) precursors and its formation regime. this work, formaldehyde (HCHO) data from Ozone Monitoring Instrument (OMI) were to analyze temporal spatial distribution HCHO vertical column densities (VCDs) Shanghai 2010 2019. VCDs exhibited highest value summer lowest winter, high VCD...

[1] This paper presents the first retrievals and validations of ozone vertical distributions from a set of high-resolution nadir thermal infrared measurements. These were obtained by the Interferometric Monitor for Greenhouse gases (IMG) instrument, which has operated on board the Japanese ADEOS platform between 1996 and 1997. The Optimal Estimation Method is used for the retrievals, along with...

[1] We investigate rapid around-the-world transport of a smoke aerosol plume released by intense forest fires in southeastern Australia in December 2006. During the first half of December 2006, southeastern Australia suffered from severe drought and exceptionally high temperatures. On 14 December 2006, a passing cold front in combination with the intense heat from the fires causing pyro-convect...
