About the measurements of Black Carbon during the Green Light World Flight 2012 and the flight to the North Pole in 2013

Matevž Lenarčič flew around the World and to the North Pole
Combustion of carbonaceous fuels for the production of energy inevitably results in the emission of gas and particulate air pollutants. A large fraction of the emitted particles are light absorbing carbonaceous aerosols. The most measured component is aerosol black carbon – a unique primary tracer for combustion emissions as it has no non-combustion sources. It is inert and can be transported over great distances (Bodhaine, 1995; Sciare 2009), even though its lifetime in the atmosphere is relatively short and measured in days or weeks.
Black carbon affects the optical properties of the atmosphere when suspended, leading to local heating or cooling, depending on the processes involved (Menon 2002, Hansen 2000). It is recognized as the second most important cause of global warming with a contribution between 20% and 40% with a significant regional heterogeneity (Ramanathan 2008). Measurements of black carbon in global background locations are scarce (Bodhaine 1995, Hansen 1989) and only recently have there been in‐situ measurements performed by airborne platforms (Spackman 2011).
We have demonstrated during the GLWF2012 round-the-world campaign and GLWF2013 a flew over the North pole, that a lightweight aircraft can provide valuable information on BC concentrations, their regional heterogeneity and vertical profiles with a minor payload and for a fraction of the cost associated with large airborne platforms (Močnik 2012).
