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.
NEWA Provides:
Hourly data on rainfall,
temperature, leaf wetness, relative
humidity, and soil temperature
Daily weather data summaries
from weather stations in growers’
fields
Degree days for base 32 F, 40 F,
43 F, 45 F, 48 F, 50 F, and 55 F
Baskerville Emin degree days for
base 43 F and 50 F
