FLEXPART Training Course

FLEXPART training course 2013 group

The course was a very successful - here are the happy participants, organiser and lecturer!
The original announcement will remain available here. A new course is not planned at this moment but quite possible.

FLEXPART calculation


15 - 17 April 2013 (Monday morning - Wednesday noon)

Note that this is the week right after the EGU 2013 General Assembly, also taking place in Vienna.


Exner room Dept. of Meteorology and Geophysics, Univ. of Vienna, Vienna, Austria

The course will take place in the Exner room (see photo to the right) which provides excellent possibilities for hands-on exercises.


Petra Seibert, Dept. of Meteorology and Geophysics, Univ. of Vienna

Petra Seibert, professor of theoretical meteorology, is a co-developer of FLEXPART from the very beginning.


Delia Arnold, Central Institute of Meteorology & Geodynamics, Vienna.

Delia Arnold, postdoctoral researcher, is a co-developer of the WRF FLEXPART version, has worked with various FLEXPART applications at UPC-INTE, BOKU-Met, and ZAMG. She was the instructor of the first FLEXPART course held in 2012 at UPC-INTE.


FLEXPART is a freely available Lagrangian particle dispersion model. It is widely used for research and operational applications, in the context of atmospheric problems from mesoscale to global scale. Primarily, it is designed for ECMWF model level and GFS pressure level input data. Ports exist for several limited-area models, inter alia MM5, WRF, COSMO, ALADIN. The main developer is Andreas Stohl.

The training course will be suitable for those who are new to FLEXPART as well as for intermediately experienced users who want to expand their knowledge and share experiences with others. A minimum background in atmospheric transport modelling is expected, and some experience in using Linux will be very helpful for hands-on exercises (and for using FLEXPART in general!).


  • Basics of FLEXPART and theoretical background
  • FLEXPART structure and logics
  • Versions of FLEXPART and input data (extraction not included)
  • Installation and compilation (hands-on)
  • Fwd example (hands-on), set-up guidelines, understanding the output
  • Bwd example (hands-on), set-up guidelines, understanding the output
  • Typical problems, how to identify and solve them
  • Processing and visualisation of output
  • Examples and applications, discussion with participants


TTORCH - ESF research network on greenhouse gas monitoring and modelling A small fee (exact amount not yet determined, maybe 50 Euro) will be levied to cover organisational expenses.
Participants have to take care themselves of accomodation (rooms cost from EUR 50 per night up; cheaper options such as a shared flat can probably be organised).
Support from TTORCH is being requested, if given, it will allow to waive the fee and to cover accommodation and/or travel expenses for some participants. Note that priority will be given first to participants from TTORCH countries (AT, CH, DE, ES, FI, FR, NL, NO, SE) and then to other ESF member countries.


The course is filled and no more applications are accepted.
