P. (Peter) Baas


I am a researcher at the department of Geoscience and Remote Sensing. I have a background in meteorology. In 2009, I obtained a PhD in atmospheric sciences with a thesis entitled ‘Turbulence and Low-Level Jets in the Stable Boundary Layer’.


My research focuses on stably stratified ‘nocturnal’ boundary layers. I am interested in the feedbacks and interactions between atmospheric turbulence and the underlying surface. In my work, I make extensive use of tall measuring towers like, for example, a 200-m tower at Cabauw that is operated by KNMI. Guided by observations from measuring facilities like these, I assess the performance operational numerical weather forecasting models.

Other activities

Apart from my work for the TU Delft, I work two days per week for Whiffle BV. Whiffle is a company, also located in Delft, that produces fine-scale operational weather forecasts for the wind energy sector.
