The effectiveness of large-scale surface albedo changes as an ozone control strategy is investigated. These albedo changes are part of the Cool Communities strategy that calls for the use of lighter colored roofing and paving materials as well as an increase in tree planting. The advanced mesoscale model MM5 was used to analyze the associated effects on ambient temperature, mixing depth and winds. The MM5 model was modified to accept surface properties derived from a satellite-based land use database. Preprocessors were also developed to allow a research-oriented model such as MM5 to be user friendly and amenable to practical, routine air quality modeling applications. Changes in ozone air quality are analyzed with the Urban Airshed Model (UAM). Results of the MM5/UAM simulations of the SCAQS August 26--28, 1987 ozone episode are presented and compared to those obtained with the CSUMM/UAM models.
