ATMOSPHERE MONITORING VIRTUAL RESEARCH CENTRE RESEARCH INFRASTRUCTURE GROUP

Presentation of the RI group
The group operates an aerosol research and education platform (BpART) in Budapest for the purpose of identifying, un-
derstanding and characterising interactions between particles and urban air environment, and determining the medical, cli-
matic and other environmental consequences of aerosol formation processes, particularly atmospheric nucleation using
advanced experimental and evaluation methods. They developed a four-wavelength photoacoustic aerosol monitoring system
for the real-time measurement of the optical absorption spectrum of aerosol particles. They also developed a family of aerosol
size distribution and concentration measurement instruments based on laser optics. They use new MICADAS accelerator
mass spectrometry (AMS) extended with a multifunctional sample preparation and gas handling system to identify the
source of aerosol particles by 14C/12C isotope ratio measurement. Urban aerosol pollution is monitored in the long- and
short-term with sampling, analysis and model calculation. Automatic gas analysers and meteorological sensors are fitted on
TV towers to determine the concentrations of greenhouse gases and their vertical fluxes between the biosphere and the at-
mosphere. The infrastructure is one of the priority greenhouse gas measurement station of the European Union, and is also
part of the Global Atmosphere Watch (GAW). In the geophysical observatory, continuous atmospheric electricity, iono-
sphere and magnetosphere measurements take place. The installed micrometeorological and trace gas measurement system
are used to determine the nitrogen cycling between various ecosystems. A HRPT (High Resolution Picture Transmission)
receiving station is operated to receive the data of Earth observation satellites. The background air pollution monitoring
station is used by an international project to measure the size distribution and concentration of atmospheric aerosol, the
chemical composition and radiation transfer properties of aerosol particles and precipitation, and the mixing ratio of trace
gases. The RI group also operates a system suitable for measuring fog properties, and is developing an air pollution forecasting
system which takes into account interactions between atmospheric water and aerosol particles.atmospheric water and aerosol

Status of the RI group: operating network spheric nucleation in the air quality in Budapest and the
Carpathian Basin; identification of the additional health risk of
ultrafine particles; examination of the long-range transport and
role of atmospheric aerosol particles and trace gases in climate
modification; and the more accurate characterisation of complex
atmospheric aerosol sources.
