Advanced In-situ Aerosol Measurement Techniques

The aim of the course is to allow students to specialize in in-situ methods for aerosol measurements. The course focuses on the most important techniques of the in-situ sensing of aerosols and measuring their physical, chemical and optical properties. Students can obtain practical experience in measurements with the instrumentation, including recently developed aerosol absorption instruments in Slovenia.

In order to successfully understand the material requires the prior knowledge of some chapters of chemistry, physics, meteorology and mathematics.

1. Introduction
2. Health and climate effects of air pollution
3. Measurement methods – in-situ
   • size distribution
   • scattering
   • absorption
   • mass concentration
   • chemical composition
   • aerosol mass spectrometers
4. Source apportionment
   • PMF
   • Aethalometer model
   • New models
5. Field work and data processing

Knowledge and understanding:
Students will be able to use the instrumentation and understand the principles and methods for in-situ sensing and properly treat, analyze and interpret data provided by the instrumentation. They will also be able to perform (un)supervised measurements.

Seminar (50%) and report from practicals (50%).
