Abstract
The paper evaluates the experience of creating a regional monitoring system for the turbulent energy exchange of the atmosphere with the underlying surface. An original technology for building an observation network based on ultrasonic automatic weather stations of domestic production has been developed. Based on the developed technology, the TomskFluxNet system has been deployed in Tomsk - the first urban network of observations of the characteristics of turbulent energy exchange of the atmosphere with the surface in Northern Eurasia with a pronounced continental climate. The first experimental results were obtained, on the basis of which significant differences in turbulent heat and momentum flows over urban and natural underlying surfaces were revealed. The results can be used to verify and improve the parameterization of the urban surface, which are actively developing in land-air models and weather forecast.
