Scholarship 16: Atmospheric Physics and pollution
Study of short-lived polluting compounds in the atmosphere
The research project concern the study of short lived polluting compounds in the atmosphere, in particular the absorbing fraction of aerosol particles. Atmospheric aerosols, especially in the accumulation mode, are efficient scatterers of solar radiation because their size is of the same order as the wavelength of radiation; some aerosol particles, such as soot and black carbon, also absorb radiation, with a significant impact on Earth radiative budget. Black carbon has several warming effects on Earth and also impacts human health, causing human morbidity and premature mortality.
In this project several measurement technologies for black carbon/absorption coefficient will be adopted and intercompared for a comprehensive absorption characterization of anthropogenic and natural aerosols, utilizing urban and remote stations of the ISAC CNR. In-situ instrumentation and methods can be used to assess the relationship between absorption and BC mass concentration at representative sites for a better determination of the BC mass absorption cross section (MACBC), which depends on a wide variety of additional variables such as the size, morphology and mixing state of the particles, amount of scattering material, and relative humidity.
This scholarship is funded by ISAC-CNR and the successful applicant, after the courses/training period, will carry out the research at the CNR-ISAC laboratories in Bologna. The Institute of Atmospheric Sciences and Climate (CNR-ISAC) aims at an integrated scientific understanding of the atmosphere, the ocean and their processes, by means of a multidisciplinary approach which combines scientific and technological skills in meteorology, climate, atmospheric dynamics and composition, Earth observations; it develops basic research, theoretical, experimental and numerical, and modeling work together with impact evaluation.
ISAC is the largest CNR Institute on atmospheric sciences, structured in 7 Units over the country, 7 permanent observatories, including 3 Global Stations of the Global Atmosphere Watch (GAW) program of the World Meteorological Organization (WMO) and 2 atmospheric research Supersites.
ISAC is recognised internationally through its collaboration with a large number of European laboratories, and research centers worldwide.
