ESCAPE Young Scientist Summer School (YSSS)

University of Copenhagen, Denmark - 7 - 12 August 2017


This YSSS will introduce young generation of researchers in numerical weather prediction, ocean, climate relevant topics as well as modern computational physics & energy efficient computing. During the school, the pa
rticipants will get familiar with ESCAPE dwarfs – fundamental algorithmic building block – and recognize why HPC and energy‐efficient computations are important. The programme will include theoretical lecture material as well as practical exercises (to be realized by students as small‐scale research projects started from the 1st day of the school with defence of project results) on selected dwarfs.


  • Block 1. Fundamentals of atmospheric processes and modelling
  • Block 2. Numerics, assimilation, evaluation and verification
  • Block 3. ESCAPE dwarfs
  • Block 4. Hardware, benchmarking, diagnostic tools for code development and improvement
  • Practical Exercises as Small‐Scale Research Projects (SSRP) on selected ESCAPE dwarfs to be realized by groups of students led by teachers (designers of the dwarf)
The full programme is available in the Summer School Booklet.
