Tom Horst

I am a Senior Scientist within the Earth Observation Laboratory of NCAR and the lead scientist for the Integrated Surface Flux System (ISFS). My personal interests encompass all aspects of turbulence, micrometeorology (in particular the measurement of surface fluxes), and boundary layer meteorology.
