The Arizona Meteorological Network (AZMET) is a near-real time ag-weather information system for Arizona. A single personal computer running inexpensive bulletin board software controls all phases of the AZMET system including data retrieval from remote weather stations, data management, and development and dissemination of weather-based information. The public gains access to AZMET information through a computer bulletin board system (BBS). Weather-based information for irrigation management is updated daily on the BBS in an ET report that summarizes raw data and estimates of actual evapotranspiration (ETa) for the most recent 14-day period. Applied research related to AZMET is presently focused on refining and/or developing new crop coefficients to convert Penman-based reference crop evapotranspiration values (ETb) to ETa.
