Heating Rate of Light Absorbing Aerosols

Heating Rate of Light Absorbing Aerosols

Scientific paper published in Environmental Science & Technology journal presents a novel methodology for experimental quantification of heating rate induced by light absorbing aerosols (LAA) (Black Crabon – BC and Brown Carbon – BrC) into an atmospheric layer.

Multiwavelength aerosol absorption measurements, performed by the Aethalometer, were coupled with spectral measurements of the direct, diffuse and surface reflected radiation to obtain highly time-resolved measurements of heating rate apportioned in the context of LAA species (BC, BrC, dust), sources (fossil fuel, biomass burning), and as a function of cloudiness.

One year of continuous and time-resolved measurements of heating rate were performed in the Po Valley, which allowed experimental determination of its seasonal behavior and daily cycle.

EXPOSURE TO BLACK CARBON DURING CYCLING

EXPOSURE TO BLACK CARBON DURING CYCLING

In the 2017 winter-spring period we performed static and mobile measurements of Black Carbon using our Aethalometers at different sites and cycling routes in Celje, Slovenia.
The results show that street intersections along the cycling routes influence the cyclists’ exposure to Black Carbon and should be as few as possible when planning cycling routes in urban areas.
Exposure can be greatly reduced by moving the cycling route away from busy roads, hence we proposed an alternative route and show that traffic planning and management should include all modes of transport.

Total Carbon Analyzer

Total Carbon Analyzer

The Magee Scientific Real-Time Total Carbon Analyzer, Model TCA-08, is a revolutionary scientific instrument that measures the Total Carbon Content (TC) of suspended aerosol particles in near-Real Time.

Total Carbon Analyzer enables continuous analysis of Total Carbon content of aerosol with two identical flow channels for sampling and analysis.

REAL-TIME
Timebase for sampling and analysis is adjustable from 15 minutes to 24 hours.

NO GAS, NO GLASS
Ambient eir is used as carrier gas at low flow rate so there is no need for gas supplies.

Rugged elements and chambers are made of stainless steel with no glass.

OC/EC DETERMINATION
In combination with Aethalometer AE33 the TCA-08 provides a complete identification and quantitation of the carbonaceous component of ambient aerosols in near-Real Time.

PLUG & PLAY
This enables easy maintence, operation and instalation of the instrument.

Total Carbon Analyzer model TCA-08 comes in a rugged instrument package suitable for laboratory and Air Quality monitoring applications.
