Oznake: secondary organic aerosols;brown carbon;particle dispersion model;ultrahigh-resolution FT-ICR MS;Pico Mountain Observatory;
Aerosol properties are transformed by atmospheric processes during long-range transport and play a key role in the Earth’s radiative balance. To understand the molecular and physical characteristics of free tropospheric aerosol, we studied samples collected at the Pico Mountain Observatory in the No ...

Long-range transported free tropospheric aerosol was sampled at the PMO (38°28’15’’N, 28°24’14’’W; 2225 m amsl) on Pico Island of the Azores in the North Atlantic. Filter-collected aerosol during summer 2012 was analysed for organic and elemental carbon, and inorganic ions. The average aerosol ambie ...

Morphology and mixing state of aged soot particles at a remote marine free troposphere site
Swarup China, Barbara Scarnato, R. Chris Owen, Bo Zhang, MarianT. Ampadu, Sumit Kumar, Katja Džepina, Michael P. Dziobak, Paulo Fialho, Judith A. Perlinger

Oznake: atmospheric aerosol;soot;long-range transport;free troposphere;single scattering albedo;
The radiative properties of soot particles depend on their morphology and mixing state, but their evolution during transport is still elusive. Here we report observations from an electron microscopy analysis of individual particles transported in the free troposphere over long distances to the remot ...

Oznake: atmospheric aerosols;ice nucleating particles;long-range transport;optical microscopy;electron microscopy;Pico Mountain Observatory;
Long-range transported free tropospheric particles can play a significant role on heterogeneous ice nucleation. Using optical and electron microscopy we examine the physicochemical characteristics of ice nucleating particles (INPs). Particles were collected on substrates from the free troposphere at ...
