XXIV Workshop "Siberian Aerosols" in Tomsk

has presented the instrumentation that is used in our group for studying aerosol and gases in the atmosphere and has presented her work on COBACC feedback loop.

The Institute has many laboratories and centres studying and developing methods in atmospheric spectroscopy, remote sensing, wave propagation and measurements of atmospheric components. investigates the chemical and physical properties of atmospheric aerosol as well as studies the composition and fluxes of gases in the ambient air. The laboratory operates several stations in the vicinity of Tomsk as well as conducts airborne measurements on the aircrafts.

Station Fonovaya (Background) is located 60km from Tomsk [see picture below]. In the station, there is a gas flux measurement tower as well as continuous aerosol size distribution measurements. In the tower there are 2 measurement points at 10 and 30m. The aerosols are measured in range of 2nm-10μm. In addition, snow and aerosol chemical composition is measured in an offline regime.

performs measurements of aerosol optical properties and conducts laboratory investigations at Big Aerosol Chamber (BAC), where the formation of combustion aerosol is studied. Olga and Ekaterina have visited inside of the BAC and it turned out to be truly Big!

In second half of 2018 INAR and V.E. Zuev Institute of Atmospheric Optics will start continuous measurements deploying Particle Size Magnifier (PSM) and Neutral clusters and Air Ions Spectrometer (NAIS) at station Fonovaya. In addition, measurements using CI-APi-TOF will be conducted on a campaign basis.
