Advanced analysis of atmospheric processes and feedbacks and biosphere-atmosphere interactions

Intensive field course

Hyytiälä Winter School 2015 – Atmospheric Processes and Feedbacks and Atmosphere-Biosphere Interactions

The winter school is organized by the University of Helsinki, Division of Atmospheric Sciences at the Hyytiälä Forestry Field Station, Southern Finland, on March 15-26, 2015.

Deadline for registration is February 1st.

Registration: for the course is done by filling the online form. Students accepted to the course will be notified by February 9th.

Prof. Markku Kulmala is the leading teacher and the course will be held in cooperation with Doctoral Programme in Atmospheric Sciences (ATM-DP), Impact of Biogenic versus Anthropogenic emissions on Clouds and Climate: towards a Holistic UnderStanding (BACCHUS), Cryosphere-Atmosphere Interactions in a Changing Arctic Climate (CRAICC), Pan-Eurasian Experiment (PEEX), Biosphere-Carbon-Aerosol-Cloud-Climate Interactions, Nordic graduate school (CBACCI), Cosmics Leaving OUtdoor Droplets Network (CLOUD), and Aerosols, Clouds and Trace gases Research InfraStructure Network (ACTRIS).

Course content and aims:

The course is based on intensive work in small groups, with MATLAB being the main tool for statistical analysis. This course in particular has the following main topics:

  • feedback loops related to atmosphere-biosphere interactions
  • day-time nucleation in Hyytiälä boreal forest environment
  • exceptionally warm winter 2013-2014
  • ice nucleation

Some of the transferable skills the course strives to improve:

  • statistical analysis and use of MATLAB
  • multidisciplinary approach
  • project management
  • collaborative learning
  • broadening of the personal comfort zone
  • introduction to SMEAR II measurement station

The course involves 1-2 short relevant lectures per day, with the main emphasis placed on intensive group work and final report written after the course. The course is aimed at PhD students in atmospheric and biospheric sciences. During the course the students will utilize long-term aerosol, air ion, trace gas, meteorological and ecophysiological data measured at several stations in order to learn advanced data treatment and data analysis methods. The main tool used on the course is MATLAB.

Exam: Students write a scientific report based on the results from analysis done during the course

The course fee is 1600 EUR and it covers:

  • all academic and social programme during the course
  • access to the electronically provided course material
  • accommodation in two-person rooms at the Hyytiälä Forestry Field Station during the course
  • evening snacks on March 15, five daily servings between March 16-25 (breakfast, lunch, afternoon coffee, dinner, evening snacks) and breakfast on March 26
  • transportation from Helsinki to Hyytiälä on March 15, and from Hyytiälä to Helsinki on March 26 (service to/from Helsinki-Vantaa airport is available)
