About

I am a researcher, mostly working on turbulent processes in the atmospheric boundary layer, using (and developing) tools like large-eddy simulation and conceptual models.

Study and work

After my meteorology study at the Wageningen University (Netherlands), I obtained my doctoral degree at the Max Planck Institute for Meteorology in Hamburg (Germany). I currently work at the Royal Netherlands Meteorological Institute (KNMI).

Model development

Both professionaly and as a hobby, I enjoy programming and developing (meteorological) models. Over the years I have been involved in the development of several models, most notably the work on MicroHH and CLASS.

MicroHH

MicroHH is a computational fluid dynamics code, made for DNS and LES studies of turbulent flows in the atmosphere. The model was designed from scratch in C++, with the goal to create a a fast and highly parallel code, capable of running on >10000 CPU cores. In addition, it is capable of running on Graphical Processing Units (GPUs) using NVIDIA's CUDA-C language. The current version supports a wide variety of setups, ranging from neutral channel flows to cases with precipitating convection. The reference paper of MicroHH 1.0 is available online.

CLASS

CLASS is a conceptual (mixed-layer) model intended to study the convective boundary layer, and its coupling to the soil, land-surface, chemistry, and clouds. It was developed as part of our book: Atmospheric Boundary Layer: Integrating Chemistry and Land Interactions.. We provide several versions, including an educational version with graphical user interface, and research versions written in Python and Fortran. More information is available on the CLASS website.
