NEWA - IPM's Network for Environment & Weather Applications

Weather Information and Pest Forecasts

What is NEWA?

NEWA is a network of electronic weather instruments, associated pest forecast models, and radar weather forecasts. New York State IPM Program staff provide technical and administrative support.

Weather instruments are purchased by individuals or groups who contribute the data collected by their weather instruments to the NEWA network and web pages. In this way, NEWA makes it possible for growers of grapes, onions, potatoes, apples, and other crops to share resources for weather data collection, analysis, distribution, and archiving.
