It is crucial to have well-defined validation cases to evaluate complex atmospheric flow models and control model inputs.

It has previously been shown that average wind conditions measured at the 250 m meteorological mast at Østerild in Denmark often resemble idealized conditions expected for flat homogeneous terrain.

In a new paper, Peña, Kosović, and Mirocha (2021) model three idealized atmospheric boundary layers at Østerild (neutral, unstable, and stable) using WRF-LES and compare results against measurements and Monin–Obukhov similarity theory. The model setup is well described, allowing peers to repeat the validation cases for similar model evaluations.

The WRF-LES simulations reproduce the measurements well, and future research will explore running WRF-LES in real-time and evaluate WRF-LES for steep terrain, which is a difficulty of WRF.
