Description/achievement of initiative
In the framework of the RaWDAR: Black Carbon Raman Wavelength Detection and Ranging initiative, the Institute has been investigating the presence of soot and black carbons in the atmosphere which might be caused by natural sources emissions, such as forest fires, but also by human activities. One of the main goals of the initiative is to develop advanced vibrational spectroscopies of carbonaceous nanoparticles in the gas phase. Raman scattering will be implemented, in conjunction with the detailed understanding of the pertinent spectral features for the speciation of carbon nanoparticles in the gas phase. In particular, the main developments are aimed at the development and use of Raman scattering for the teledetection of soot in the gas phase.
One application will be the monitoring of the northern region of Vietnam: south-east Asia is poorly characterized yet although the strong emission sources are numerous, from coal mines to power plant and transportation as well as biomass burning with a strong impact in the Ha Long bay for instance.
