Abstract:
The North Dakota Agricultural Weather Network (NDAWN) consists of 70 automated weather stations
distributed among prime agricultural locations across North Dakota, the Red River Valley, and border regions of
surrounding states. The NDAWN Center is a part of the Department of Soil Science, North Dakota State
University. The NDAWN stations measure wind speed and direction, air temperature, rainfall, solar radiation,
pressure (32 stations), atmospheric moisture and soil temperatures under bare and turf at 10 cm (4 inch) depth.
The center provides daily summaries consisting of maximums and minimums as well as time of occurrence, and
various totals or averages for all variables in English or metric units. Measured and calculated variables along
with complete descriptions are available. The NDAWN Center web site: http://ndawn.ndsu.nodak.edu/ allows
direct access to NDAWN data in various special and temporal scales. The voice modem accommodates those
who do not have internet access. The NDAWN Center has assisted many North Dakotans in making weather
critical decisions concerning their crops, livestock, and livelihood. One direct benefit of NDAWN data was
helping to save the 1993-94 potato crops in North Dakota. The stations provide weather data, which was
instrumental in developing an agricultural model called the late blight model. This model predicts when leaf
disease can occur in potato plants. Late blight doesn’t occur in North Dakota every year and is prevalent during
cool and moist periods of weather. In 1993-94, this model predicted that late blight would occur and growers
were able to use fungicide applications to prevent the disease. Another direct benefit of NDAWN data is that it
provides universities and the National Weather Service with an additional database for research and forecasting
applications. Agriculture remains the number one industry in North Dakota and its success will always be
dependent on the weather.
