An automatic collector to monitor insoluble atmospheric deposition: application for mineral dust deposition
Deposition is one of the key terms of the mineral dust cycle. However, dust deposition remains poorly constrained in transport models simulating the atmospheric dust cycle. This is mainly due to the limited number of relevant deposition measurements. This paper aims to present an automatic collector...

| description | Deposition is one of the key terms of the mineral dust cycle. However, dust
deposition remains poorly constrained in transport models simulating the
atmospheric dust cycle. This is mainly due to the limited number of relevant
deposition measurements. This paper aims to present an automatic collector
(CARAGA), specially developed to sample the total (dry and wet) atmospheric
deposition of insoluble dust in remote areas. The autonomy of the CARAGA can
range from 25 days to almost 1 year depending on the programmed sampling
frequency (from 1 day to 2 weeks respectively). This collector is used to
sample atmospheric deposition of Saharan dust on the Frioul islands in the Gulf
of Lions in the Western Mediterranean. To quantify the mineral dust mass in
deposition samples, a weighing and ignition protocol is applied. Almost 2
years of continuous deposition measurements performed on a weekly sampling
basis on Frioul Island are presented and discussed with air mass
trajectories and satellite observations of dust. Insoluble mineral
deposition measured on Frioul Island was 2.45 g m<sup>−2</sup> for February to
December 2011 and 3.16 g m<sup>−2</sup> for January to October 2012. Nine major
mineral deposition events, measured during periods with significant MODIS
aerosol optical depths, were associated with air masses coming from the
southern Mediterranean Basin and North Africa. |
