Goal
Investigate the impacts of urban warming on outdoor residential water demand in Tucson, Arizona.

Objectives
1. Characterize spatial and temporal trends in Tucson's thermal profile over the period 1984-2006. Assess trends in reference evapotranspiration (ETref).
2. Spatially correlate normalized difference vegetation index (NDVI) and surface temperature vs. outdoor water demand and ETref based on 2000-2006.
3. Compile datasets of NDVI and surface temperature, and make the datasets available over the Internet for use by managers, planners, ecologists, and researchers.
