Global survey of tropospheric vertical column (VC) NO2 for 2009. Clearly visible are the industrialised regions in the northern hemisphere and the regions of biomass burning in the southern hemisphere. The inset illustrates how NO2 concentrations have risen in China from 1996-2009. The trend analysis uses data from GOME (1996-2002) and SCIAMACHY (2003-2009). While 'old' industrialised countries were able to stop the increase of NO2 emissions, the economical growth in China turns out to be a strong motor for pollution. (Courtesy: A. Richter, IUP-IFE, University of Bremen)

The Antarctic ozone hole in 2002 (left) and 2005 (right). SCIAMACHY total column ozone measurements from 25 September have been analysed with the ROSE assimilation model to generate this view. Due to meteorological conditions, the hole as split and reduced in size in 2002 but appeared 'as normal' in 2005. (Courtesy: T. Erbertseder, DLR-DFD)

Slices of the polar southern hemisphere ozone field at altitudes of approximately 20, 24 and 28 km on 27 September 2002 and 27 September 2005 as measured by SCIAMACHY. The observed split of the ozone hole in 2002 is not so obvious in the lower stratosphere around 20 km, but clearly visible at 24 and 28 km. In 2005, an ozone hole of 'normal shape' existed at all altitudes. (Courtesy: C. von Savigny, IUP-IFE, University of Bremen)

Ozone anomalies from 1979 to 2009 derived from different datasets at five NDACC stations. The anomalies are averaged over the 35-45 km range. The all-instrument average is shown in black. All time series were smoothed by a 5-month running mean. At the bottom of the right hand panel 3 proxies are given: The negative 10 hPa zonal wind at the equator for the QBO, the 10.7 cm solar flux for the 11-year solar cycle and the inverted effective stratospheric chlorine for ozone destruction by chlorine. The grey line and the grey shaded area show model simulations and their 2-sigma standard deviation.

NLC as seen from the International Space Station on 22 July 2008 (left panel), together with the NLC signature in a SCIAMACHY UV limb radiance profile from 3 July 2002 (right panel). The scattering by ice particles in the NLC leads to a significant increase of the observed limb radiance profile peaking at the characteristic NLC altitude of about 83-85 km (blue line). For comparison, a limb radiance measurement in the absence of NLC is shown in red. (Courtesy: C. von Savigny, IUP-IFE, University of Bremen; ISS photo: NASA)

At the time of the solar proton event, the ionisation rate increases and causes a drop in the NLC rate. (Courtesy: C. von Savigny, IUP-IFE, University of Bremen)

Atmospheric abundance of MgII derived from 20 orbits scanning in the mesosphere-thermosphere limb mode from 60-160 km in August 2007. The most striking feature is the strong MgII layer around 100 km extending from high northern latitudes to the equator. Courtesy: M. Sinnhuber, IUP-IFE, University of Bremen)

Atmospheric abundances of MgII derived from the nominal limb scanning from the surface up to 93 km. The strong maximum around 100 km is reproduced very well, although with lower values due to the restricted vertical resolution above 93 km. The three panels show the MgII densities at different latitude bands: 5°S-5°N (top), 25°N-35°N (mid) and 55°N-65°N (bottom). (Courtesy: M. Scharringhausen/M. Sinnhuber, IUP-IFE, University of Bremen)
