[1] More than 130 observation days of the horizontal and vertical extent of Saharan dust intrusions over Europe during the period May 2000 to December 2002 were studied by means of a coordinated lidar network in the frame of the European Aerosol Research Lidar Network (EARLINET). The number of dust events was greatest in late spring, summer, and early(More)
The relevance of water vapour in atmospheric physics and climate research contrasts strongly with the availability of humidity data in the Arctic. The most extensive humidity data set is based on approx. 80 radiosonde stations north of 60°N, but suffers from two major problems: Sensor diversity and sensor limitations under Arctic conditions, on the one(More)
We report on the observations of 188 sporadic layers of either Ca atoms and/or Ca ions that we have observed during 112 nights of lidar soundings of Ca, and 58 nights of Ca + soundings, at Kühlungsborn, Germany (54 • N, 12 • E). The Ca + soundings have been performed simultaneously and in a common volume with the Ca soundings by two separate lidars.(More)
Ozone measurements from ozonesondes, AROTAL, DIAL, and POAM III instruments during the SOLVE-2/VINTERSOL period are composited in a time-varying, flow-following quasi-conservative (PV-θ) coordinate space; the resulting composites from each instrument are mapped onto the other instruments' locations and times. The mapped 5 data are then used to intercompare(More)
Stratospheric turbulence is important for the mixing of trace species and the energy balance, but direct measurements are sparse due to the required resolution and accuracy. Recently, turbulence parameters such as the energy dis-sipation rate ε were inferred from standard radiosonde data by means of a Thorpe analysis. To this end, layers with vertically(More)
At the Leibniz-Institute of Atmospheric Physics in Kühlungsborn (54 • N, 12 • E) we have developed a daytime capable Rayleigh-Mie-Raman (RMR) lidar for the mesosphere. Temperature soundings are feasible up to approximately 75 km during the day and up to 90 km during the night. Furthermore, measurements are performed at high solar elevation angles of up to(More)
Pyrocumulonimbus (pyroCb) storms have been shown to have an eruptive dynamic and capacity similar to volcanic eruptions that penetrate into the stratosphere. Much remains unknown about pyroCb, for instance its storm structure, frequency, impact on satellite cloud imagery, and impact on regional/hemispheric climate. This study pursues in-depth exploration of(More)
The Match technique was used to determine chemically induced ozone loss inside the stratospheric vortex during the Arctic winter 2002/2003. From end of November 2002, which is the earliest start of a Match campaign ever, until end of March 2003 approximately 800 ozonesondes were launched from 30 stations in the Arctic and mid 5 latitudes. Ozone loss rates(More)
