Development of the weather network was supported through a 1995-96 grant from the USDA Agricultural Telecommunications Program to the NYS IPM Program. Continuation of NEWA after start-up depended on membership fees and grant funding. The Northeast Weather Association (NEWA), a nonprofit organization including growers, private consultants, Cornell Cooperative Extension employees, processors, and Cornell University faculty members, was established soon after the weather network was created and its board of directors managed the network.
NEWA membership fees were eliminated in 2002 and access made free-of-charge, courtesy of funding support from the NYS IPM Program. The Association was dissolved and the name changed to Network for Environment and Weather Applications to fit the NEWA acronym.
The initial weather stations used in NEWA were manufactured by Sensor Instruments, but these are no longer available. The network is also compatible with Campbell Scientific weather stations. Today, NEWA uses RainWise Inc. weather stations.
