The Office of the Arizona State Climatologist is housed within the School of Geographical Sciences at Arizona State University. Dr. Nancy J. Selover, an Academic Associate in the School of Geographical Sciences, is the State Climatologist.



The state climate program for Arizona was established by the Arizona Board of Regents in September 1973 in a Memorandum of Agreement between the Association of American State Climatologists (AASC) the National Weather Service, the National Climatic Data Center, and Arizona State University. As part of a national effort, the office was officially recognized as the AASC Recognized State Climate Office (ARSCO) for Arizona in 2001 and re-certified in 2007.


The purpose of the program is to: (1) manage and disseminate climatological information about the State of Arizona, (2) monitor the climate of Arizona and the region, (3) collaborate with state agencies in need of climate data and advisement, and (4) conduct research aimed at an improved understanding of the spatial and temporal variability of the climate of Arizona.


At present, the office continues to be entirely a service organization, receiving infrastructural support from Arizona State University. Every effort is made to provide requested climatic data with no fee; however, large requests and those that require data analysis will incur charges to help defray the associated direct costs.
