Saharan Aerosol Long-range Transport and Aerosol-Cloud-Interaction
After 5 weeks of intensive measurements,
SALTRACE field experiment ended
on 15 July 2013. We were very lucky with the weather and studied mineral
dust from several dust outbreaks with the DLR research aircraft Falcon
between Senegal and Florida. On the eastern side of the Atlantic, dust
plumes extended up to about 6 km altitude, while the dust layers in the
Caribbean were mainly below 4.5 km. Highlights during SALTRACE
included the sampling of a dust plume in the Cape Verde area on 17 June
which was again measured with the same instrumentation on 21 and 22 June
near Barbados. The event was also captured by the ground-based lidar and
in-situ instrumentation. Another highlight was the formation of tropical
storm Chantal in the dusty environment.

During SALTRACE, the DLR research aircraft Falcon was based on Sal, Cape
Verde, between 11 and 17 June, and on Barbados between 18 June and 11
July 2013. The Falcon was equipped with a suite of in-situ instruments
for the measurement of microphysical and optical aerosol properties and
with a nadir-looking 2-µm wind lidar. Ground-based lidar and in-situ
instruments were deployed in Barbados and Puerto Rico.
SAVE the DATE: First SALTRACE Workshop
on 2/3 December 2013
We will have a first 2-day workshop to coordinate the
next steps of work on the SALTRACE data set on 2/3 December 2013 in Oberpfaffenhofen.

given on the

SCIENTIFIC GOALS OF AerCARE
Aerosol particles play a key role in
shaping conditions on the Earth’s surface and in the lower atmosphere.
Aerosol particles are frequently lifted into the free troposphere and
transported as elevated aerosol layers over long distances, even between
continents. However, the impacts of these aerosol layers on atmosphere
and climate are not yet known.
The main goal of AerCARE is the
systematic investigation and assessment of the climate impacts of
elevated aerosol layers arising from anthropogenic, including air
traffic, and natural sources.
Our propsal on "A novel method to derive microphysical aerosol
properties from future satellite measurements" is selected for funding
Last preparations for SALTRACE-Falcon
are ongoing. SALTRACE-Falcon is an aircraft field
experiment which will be conducted in June/July 2013. SALTRACE-Falcon is the central field experiment for the
AerCARE project. More details are given on the
SALTRACE project homepage.
An aerosol experiment with the LMU Ultra High Sensitivity Aerosol
Spectrometer (UHSAS) has been developed for the "Instrumentenpraktikum",
and is now offered for the first time. The "Instrumentenpraktikum" is a
mandatory class for LMU bachelor students of physics + meteorology.
12 August 2012: Students perform
measurements with the LMU Ultra High Sensitivity Aerosol Spectrometer (UHSAS).
Helmholtz-University Young Investigators Groups are intended to improve
an existing link between a Helmholtz Center and a University by
enhancing collaboration activities and knowledge exchange. AerCARE is a
cooperation between DLR Oberpfaffenhofen and the
University of Munich.
Group collaborates with national and international partners (e.g.
The AerCARE Group is funded by the
through the President’s Initiative and Networking Fund, and by DLR.
