2nd International FLEXPART Training Course June 2014


A second FLEXPART Training Course has been successfully completed, all are happy! The original announcement will remain available here. There is no plan yet for the next course -- subscribe to the FLEXPART mailing list for staying informed about new developments around FLEXPART, including course announcements!

FLEXPART calculation


4-6 June 2014 (Wednesday morning - Friday)


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 has taught FLEXPART courses in 2012 at UPC-INTE and in 2013 at IMGW.


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 modellingThere is no course fee. Support from TTORCH is being requested, it is expected tocover accommodation and travel expenses of 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. Participants from non-ESF countries can usually not be supported by TTORCH grants.


A maximum of ca. 20 participants can be accepted. APPLICATIONS ARE CLOSED!
