Model: UT&C

Urban Tethys-Chloris (UT&C) is a mechanistic urban ecohydrological model combining principles of ecohydrological land surface modelling based on the T&C model with urban canopy modelling. UT&C is a fully coupled energy and water balance model that calculates 2 m air temperature and humidity, and surface temperatures. It explicitly solves biophysical and ecophysiological characteristics of ground vegetation, urban trees, and green roofs and models urban water fluxes including evapotranspiration, canopy interception, infiltration, and soil moisture transport. UT&C accounts for variations in urban densities, building properties, and urban irrigation schemes. Hence, the model is able to account for the effects of different plant characteristics on the urban climate and hydrology. In turn, it can account for the effects of the urban environment on plant well-being and productivity. UT&C relatively low computational demand allows for analyses spanning multiple years with an hourly time step, therefore, facilitating long-term and seasonal investigations.
