Recent developments in the model include the incorporation of the NARP radiation scheme (Offerle et al. 2003: Loridan et al. 2010) so net all wave radiation is not required as an input; the use of LUMPS (Grimmond and Oke 2002) to do initial calculations of turbulent heat fluxes so that stability calculations are improved; the calculation of soil moisture content so that this is no long required as an input; movement of water between the canopy and soil storages; a simple anthropogenic heat flux model (Loridan et al. 2010); and a simple urban water use model. In addition to accounting more completely for energy and water exchange processes in urban areas, SUES-2 requires less observed variables as inputs to allow the model to run, although if these data are available it can also utilize them.
In this paper, SUES-2 is presented. The model is evaluated using observations collected in Vancouver, BC, Canada, between 22 February and 28 June 1987 and elsewhere. The model is evaluated based on latent heat flux, soil moisture and surface water state observations.
