| description | In situ single particle analysis of ice particle residuals (IPRs) and
out-of-cloud aerosol particles was conducted by means of laser ablation mass
spectrometry during the intensive INUIT-JFJ/CLACE campaign at the high alpine
research station Jungfraujoch (3580 m a.s.l.) in January–February 2013.
During the 4-week campaign more than 70 000 out-of-cloud aerosol
particles and 595 IPRs were analyzed covering a particle size diameter range
from 100 nm to 3 µm. The IPRs were sampled during 273 h while the
station was covered by mixed-phase clouds at ambient temperatures between
−27 and −6 °C. The identification of particle types is based on
laboratory studies of different types of biological, mineral and
anthropogenic aerosol particles. The outcome of these laboratory studies was
characteristic marker peaks for each investigated particle type. These marker
peaks were applied to the field data. In the sampled IPRs we identified a
larger number fraction of primary aerosol particles, like soil dust
(13 ± 5 %) and minerals (11 ± 5 %), in comparison to
out-of-cloud aerosol particles (2.4 ± 0.4 and 0.4 ± 0.1 %,
respectively). Additionally, anthropogenic aerosol particles, such as
particles from industrial emissions and lead-containing particles, were found
to be more abundant in the IPRs than in the out-of-cloud aerosol. In the
out-of-cloud aerosol we identified a large fraction of aged particles
(31 ± 5 %), including organic material and secondary inorganics,
whereas this particle type was much less abundant (2.7 ± 1.3 %) in
the IPRs. In a selected subset of the data where a direct comparison between
out-of-cloud aerosol particles and IPRs in air masses with similar origin was
possible, a pronounced enhancement of biological particles was found in the
IPRs. |
