“…These detections are similar to the ones obtained by the DUSTER balloon-borne particle collector (Ciucci et al, 2011;Della Corte, 2012) and can be attributed to interplanetary dust (Brownlee, 1985).…”

Abstract. In the companion (Part I) paper, we have described and evaluated a new versatile optical particle counter/sizer named LOAC (Light Optical Aerosol Counter), based on scattering measurements at angles of 12 and 60 • . That allows for some typology identification of particles (droplets, carbonaceous, salts, and mineral dust) in addition to sizesegregated counting in a large diameter range from 0.2 µm up to possibly more than 100 µm depending on sampling conditions . Its capabilities overpass those of preceding optical particle counters (OPCs) allowing the characterization of all kind of aerosols from submicronicsized absorbing carbonaceous particles in polluted air to very coarse particles (> 10-20 µm in diameter) in desert dust plumes or fog and clouds. LOAC's light and compact design allows measurements under all kinds of balloons, on-board unmanned aerial vehicles (UAVs) and atPublished by Copernicus Publications on behalf of the European Geosciences Union. 3674J.-B. Renard et al.: LOAC: a counter/sizer for ground-based and balloon measurements -Part 2 ground level. We illustrate here the first LOAC airborne results obtained from a UAV and a variety of scientific balloons. The UAV was deployed in a peri-urban environment near Bordeaux in France. Balloon operations include (i) tethered balloons deployed in urban environments in Vienna (Austria) and Paris (France), (ii) pressurized balloons drifting in the lower troposphere over the western Mediterranean (during the Chemistry-Aerosol Mediterranean Experiment -ChArMEx campaigns), (iii) meteorological sounding balloons launched in the western Mediterranean region (ChArMEx) and from Aire-sur-l'Adour in south-western France (VOLTAIRE-LOAC campaign). More focus is put on measurements performed in the Mediterranean during (ChArMEx) and especially during African dust transport events to illustrate the original capability of balloon-borne LOAC to monitor in situ coarse mineral dust particles. In particular, LOAC has detected unexpected large particles in desert sand plumes.

“…It is an active sampling system that was specifically developed to minimise and to control contamination during autonomous flight performance. The assembled instrument itself consists of: (1) an inlet tube, (2) a collecting chamber (3), an actual collector (4) the operational blank collector, and (5) a pumping system (Della Corte et al, 2012). The operational blank collector is mounted in a smaller chamber but in communication with the collection chamber.…”

Nanometre CaO and pure carbon smoke particles were collected at 38-km altitude in the upper stratosphere in\ud the Arctic during June 2008 using DUSTER (Dust in the Upper Stratosphere Tracking Experiment and\ud Retrieval). This balloon-borne instrument was designed for non-destructive collection of solid particles\ud between 200 nm to 40 mm. We report here on micrometre CaCO3 (calcite) grains with evidence of thermal\ud erosion and smoke particles that formed after melting and vaporisation and complete dissociation of some of\ud the CaCO3 grains at temperatures of approximately 3500 K. These conditions and processes suggest that the\ud environment of this dust was a dense dust cloud that had formed after disintegration of a carbonaceous\ud meteoroid during deceleration in the atmosphere. The balloon-borne collector must have coincidentally\ud travelled through the dust cloud of a recent bolide event that had penetrated between 38.5 and 37 km altitude.\ud This work identified a previously unknown meteoric smoke forming process in addition to meteoric smoke\ud particles due to photolysis-driven oxidation of mesospheric metals from meteor ablation that had settled into\ud the upper stratosphere

“…X-ray (EDX) analysis, and infrared and micro-Raman spectroscopy, without the necessity of sample manipulation (Della Corte et al, 2012). The DUSTER design includes a collection chamber that can be sealed by ultrahigh vacuum (UHV) valves when in nonsampling mode plus a one-shot mechanism that seals the inlet pipe prior to reaching 20 km altitude during the ascent phase (Fig.…”

The stratosphere is a known host to terrestrial microbes of most major biological lineages, but it is also host to incoming meteoric dust. Our goal is to (1) introduce DUSTER (Dust in the Upper Stratosphere Tracking Experiment and Retrieval), an active collector for the nondestructive collection of nano-to micrometer particles in the stratosphere between 30 and 40 km altitude, and (2) demonstrate that even a single particle can be collected free of resident atmospheric and laboratory contaminant particles. DUSTER improves the pervasive and persistent contamination problem in the field of aerobiology research. Here, we demonstrate the collector's advances by the identification of a (terrestrial) spore particle found among a population of nanometer-scale inorganic meteoric particles. This was possible because the size, shape, morphology, and chemical composition of each particle can be determined while still on the collector surface. Particles can be removed from DUSTER for specific laboratory analyses. So far, DUSTER has not been fitted for aerobiological purposes; that is, no attempts were made to sterilize the collector other than with isopropyl alcohol. Its design and laboratory protocols, however, allow adjustments to dedicated aerobiological sampling opportunities.
