of the urban energy balance and that accounting for evaporation is important. This study makes a number of recommendations for model development and model use (Grimmond et al. 2011).
A recent international review of urban meteorology for the World Climate Congress 3 made a series of recommendations for urban meteorology. In summary (modified from Grimmond et al. 2010b):
1. Observations: More operational urban measurement stations and networks within urban areas and upwind. The stations should conform to WMO Urban Guidelines (WMO 2006, Chapter 11). The long-term measurement stations in cities should be preserved. There is a need for vertical profiles of physical and chemical variables.
