Multidisciplinary program studies land-atmosphere interactions in semi-arid regions



What are the consequences of climatic and human-induced change on the water balance and ecological diversity of the Upper San Pedro River Basin (USPB), which spans the border between southeastern Arizona and northern Sonora, Mexico? What are the effects of such change at event, seasonal, interannual, and decadal timescales? The interdisciplinary Semi-Arid Land Surface Atmosphere Program (SALSA) seeks an answer to these complex questions.
