New York Times: California Today: A Plan to Cool Down L.A.

"That’s why Los Angeles is pushing a novel plan to cool down the city: Turn the streets a different color. The idea of “cool pavements” has been kicking around City Hall for years, but only recently has it resulted in action on the ground. Matt Peterson, Los Angeles’s chief sustainability officer, said test applications of a light gray coating known as CoolSeal had shown a 10-degree reduction in heat gain."

Sharma, A.; et al. (2016): Green and cool roofs to mitigate urban heat island effects in the Chicago metropolitan area. Evaluation with a regional climate model

Sharma, A.; Conry, P.; Fernando, H. J. S.; Hamlet, Alan F.; Hellmann, J. J.; Chen, F. (2016): Green and cool roofs to mitigate urban heat island effects in the Chicago metropolitan area. Evaluation with a regional climate model. In Environ. Res. Lett. 11 (6), p. 64004–64004. DOI 10.1088/1748-9326/11/6/064004.

Urban albedo enhancement. "We have employed the urbanized version of the Weather Research and Forecasting (uWRF) model at high (1 km) resolution with physically-based rooftop parameterization schemes (conventional, green and cool), a first-time application to the Chicago metropolitan area. We simulated a hot summer period (16–18 August 2013) and assessed (i) UHI reductions for different urban landuse with green/cool roofs, (ii) the interaction of lake breeze and UHI, and (iii) diurnal boundary layer dynamics."

Salamanca, F.; et al. (2016): Citywide Impacts of Cool Roof and Rooftop Solar Photovoltaic Deployment on Near-Surface Air Temperature and Cooling Energy Demand

Salamanca, F.; Georgescu, M.; Mahalov, A.; Moustaoui, M.; Martilli, A. (2016): Citywide Impacts of Cool Roof and Rooftop Solar Photovoltaic Deployment on Near-Surface Air Temperature and Cooling Energy Demand. In Boundary-Layer Meteorol. DOI 10.1007/s10546-016-0160-y.

"We conduct a suite of sensitivity experiments (with different coverage rates of cool roof and rooftop solar photovoltaic deployment) for a 10-day clear-sky extreme heat period over the Phoenix and Tucson metropolitan areas at high spatial resolution (1-km horizontal grid spacing). Results show that deployment of cool roofs and rooftop solar photovoltaic panels reduce near-surface air temperature across the diurnal cycle and decrease daily citywide cooling energy demand."
