| Zusammenfassung |
A multi-platform field measurement campaign involving aircraft and balloons
took place over West Africa between 26 July and 25 August 2006, in the frame
of the concomitant AMMA Special Observing Period and SCOUT-O3 African
tropical activities.
Specifically aiming at sampling the upper troposphere and lower stratosphere,
the high-altitude research aircraft M55 Geophysica was deployed in
Ouagadougou (12.3° N, 1.7° W), Burkina Faso, in conjunction
with the German D-20 Falcon, while a series of stratospheric balloons and
sonde flights were conducted from Niamey (13.5° N, 2.0° E),
Niger.
Altogether, these measurements were intended to provide
experimental evidence for a better understanding of large scale transport,
assessing the effect of lightning on NOx production, and studying
the impact of intense mesoscale convective systems on water, aerosol, dust
and chemical species in the upper troposphere and lower stratosphere. The M55
Geophysica carried out five local and four transfer flights between southern
Europe and the Sahel and back, while eight stratospheric balloons and
twenty-nine sondes were flown from Niamey.
These experiments allowed a characterization of the tropopause and lower
stratosphere of the region. The paper provides an overview of SCOUT-AMMA campaign
activities together with a description of the meteorology of the African monsoon and the
situation prevailing during the flights and a brief summary of the observations accomplished. |
