Climate

Climate Science Application Program (CSAP) focuses on bringing climate science research and applications to the people of the state of Arizona and the broader Southwest region including New Mexico, southern California, and northern Mexico.

The Arizona Meteorological Network (AZMET) provides meteorological data and weather-based information to agricultural and horticultural interests operating in southern and central Arizona. Meteorological data is collected from a network of automated weather stations located in both rural and urban production settings.

Arizona receives most of its annual precipitation in two distinct seasons, winter and summer. Winter precipitation is produced by large-scale surface low pressure systems that traverse the Southwest, drawing in moisture from the Pacific Ocean.

Listen to current southwest climate information. The Climate Assessment for the Southwest (CLIMAS) program was established in 1998 as part of the National Oceanic and Atmospheric Administration’s Regional Integrated Sciences and Assessments program. CLIMAS —housed at the University of Arizona's Institute of the Environment—is a collaboration between UA and New Mexico State University.

Keeping an Eye on Drought: Satellite-based Drought Monitoring and Assessment. website uses remote sensing imagery – which takes a vegetation picture of the earth’s surface, and then takes that satellite information to allow users to actually view surface greenness.

Gridded Datasets of Daily Surface Meteorological Variables. Many areas that use agricultural and environmental science for management and planning often need historical records of daily weather for activities that range from modeling forage production to determining the frequency of freezing temperatures or heavy rainfall.

Rainlog.org is a cooperative rainfall monitoring network for Arizona. Data collected through this network will be used for a variety of applications, from watershed management activities to drought planning at local, county, and state levels.
