SimRoof: Desert Sites


Having no dry tropical TMY3 sites, we turn to deserts of the American southwest. http://wwwpaztcn.wr.usgs.gov/rsch_highlight/articles/200508.html provides a map of the Sonoran and Mojave deserts. Clockwise from top left, the states are California, Nevada, Utah, Arizona, and Baja California (Mexico). Containing the large populations centers of Las Vegas Nevada and Phoenix Arizona, simulations of these TMY3 sites should be of interest for their own sake.
