摘要：Humans directly alter surficial processes and climate at the local or "neighborhood" scale (typically on the order of hundreds of hectares) where process - response is not well understood. Investigation of surficial processes at this scale requires very high resolution (both spatial and spectral) data over a wide wavelength range. Commercial data from satellite-based sensors such as IKONOS and Quickbird now provide excellent spatial resolution in the visible through near-infrared wavelengths; however data with high spectral and spatial resolution at longer wavelengths, particularly the mid-infrared, are still the province of multispectral to hyperspectral airborne sensors. Superspectral data acquired by the NASA MASTER airborne sensor is being used to investigate social-biogeophysical microclimate interactions in Phoenix, Arizona neighborhoods. This sensor acquires data in 50 bands in the visible through mid-infrared wavelengths, placed to match the bandpasses of the satellite-based MODIS and ASTER instruments. Ground resolution of data acquired over the Phoenix metropolitan region varies from 5 – 12 m/pixel depending on aircraft height. Surface temperature and vegetation density spatial variations between neighborhoods spaced along an income gradient in Phoenix have been mapped using 12 m/pixel data. These data correlate with ethnicity and income level, and demonstrate inequity in the microclimates experienced by Phoenix residents
