Black carbon pollution research - ASIA 2018

The GLWF 2018 mission will look for evidence for two big environmental issues which significantly contribute to the accelerated pace of global warming: enormous forest fires and transport of desert dust of Asia.

The incomplete combustion of fuels containing carbon (such as gasoline, diesel, natural gas, wood and other biomasses) results in the emission of aerosols, small particles which pollute the air and are harmful to people’s health. An important part of these emissions is soot, known by its scientific name: Black Carbon (BC). It is inert and can be transported over great distances. It also highly absorbs sunlight, which is the reason for its name – it has a very black appearance.

BC heats the atmosphere through the absorption of sunlight and is recognized as a very important cause of global warming, second only to CO2. Although BC measurements can increase the knowledge on these topics, they are scarce at global background locations. The GLWF flights are an opportunity to carry out measurements on such a scale. We modified the aircraft and installed an aerosol inlet on the wing, with tubing carrying the sampled air to the prototype Aethalometer – the instrument for measuring BC we developed for this very occasion.

We have demonstrated during the previous GLWF round-the-world and the North Pole campaigns that an instrumented ultra 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. We trust that the campaigns will initiate a change of the measurement paradigm and a start of measurements campaigns on a really large scale.

PILOT - Matevž Lenarčič

Matevž Lenarčič

Matevž Lenarčič is experienced long distance flier. He has flown for more than 3500+ hours all over the world, mostly with his ultra light airplane and other single engine aircrafts. He holds PPL - private pilot license with IFR - (instrumental flight rules) rating, night qualification, and ULPL - ultralight pilot license.

Matevž Lenarčič has graduated in biology. An alpinist, paraglider, environmentalists, photographer and a pilot, he has climbed all over the world and among others reached the top of 8051m Broad Peak in Himalaya and climbed extreme routes in Patagonia. He is author of 11 books (nature, photography, climbing and flying), some of them awarded and translated in several languages. He is also founder and director of Aerovizija d.o.o., company for aerial photography.

RESEARCH - Dr. Griša Močnik

Griša Močnik

Assist. Prof. Dr. Griša Močnik, is an aerosol researcher at the Jozef Stefan Institute, Slovenia. He was the director of research and development of Aerosol, the company where black carbon instruments are produced. He received his doctorate from the University of Ljubljana while working at J. Stefan Institute, and universities and institutes in the Netherlands, France and Germany, where he performed research on photothermal and photoacoustic methods for investigation of highly absorbing and scattering samples. Before that he studied physics at the University of Ljubljana.

Griša Močnik has been a principal investigator, researcher and scientific advisor in numerous development and research projects in the field of aerosol instrumentation and laser devices. His work is mostly focused on the development of instrumentation for research of aerosol optical properties and application of this instrumentation – in particular measurement of black carbon and other light absorbing carbonaceous aerosols. His current research includes source apportionment of carbonaceous aerosol for local studies and in context of long range transport; vertical profiles of primary combustion products; and methods for emission measurements. He served as a member of the United Nations ECE expert group on Black Carbon.
