{{Short description|Mesonet run by Washington State University}}
'''AgWeatherNet''' is an automated agricultural [weather station network](/source/weather_station_network) operated by [Washington State University](/source/Washington_State_University) in the [Pacific Northwest](/source/Pacific_Northwest).<ref>{{cite book | last=Zhang | first=Q. | title=Automation in Tree Fruit Production: Principles and Practice | publisher=CABI | year=2017 | isbn=978-1-78064-850-7 | url=https://books.google.com/books?id=RY1FDwAAQBAJ&pg=PA115|page=115}}</ref> It is the first and the largest agricultural weather network in the United States.<ref name=Yates>{{citation|author=Scott Yates|work=Wheat All About It! |title=Let's Talk About AgWeatherNet|id=episode 49|url=http://wagrains.org/podcast/episode-49-lets-talk-about-agweathernet/ |type=podcast|publisher=[Washington Grain Commission](/source/Washington_Grain_Commission)|date=November 28, 2017}}</ref> Every 5 seconds, over 175 sensors (as of 2018) record air temperature, [relative humidity](/source/relative_humidity) and [dew point](/source/dew_point), soil temperature at 8 inches, rainfall, wind speed, wind direction, [insolation](/source/insolation)  and leaf wetness.<ref name=Yates/><ref name=homepage>[http://weather.wsu.edu AgWeatherNet user homepage], Washington State University, retrieved 2018-05-05</ref> The data is reported back from each sensor to WSU's Irrigated Agriculture Research and Extension Center in [Prosser, Washington](/source/Prosser%2C_Washington) and made available to the public on the Internet. The network can be used to predict and warn of crop hazards such as freezes (especially damaging to Washington fall crops like apples) and hailstorms.<ref>{{citation|publisher=Washington State University College of Agricultural, Human, and Natural Resource Sciences|title=AgWeatherNet Tests State-of-the-Art Weather Prediction Model for Freeze Events|type=official website|date=August 23, 2012|author=Nella Letizia|url=http://stage.cahnrs.wsu.edu/news-release/2012/08/23/agweathernet-tests-state-of-the-art-weather-prediction-model-for-freeze-events/|access-date=March 6, 2018|archive-url=https://web.archive.org/web/20180306082946/http://stage.cahnrs.wsu.edu/news-release/2012/08/23/agweathernet-tests-state-of-the-art-weather-prediction-model-for-freeze-events/|archive-date=March 6, 2018|url-status=dead}}</ref>

Sensors are located mostly in the irrigated regions of [Eastern Washington](/source/Eastern_Washington) like the [Yakima Valley](/source/Yakima_River), but also cover some non-irrigated areas like the [Palouse](/source/Palouse) and areas of [Western Washington](/source/Western_Washington) such as the [Chehalis River](/source/Chehalis_River_(Washington)) valley.<ref name=Yates/><ref>{{citation | title=WSU AgWeatherNet: a tool to plan and manage farm operations | publisher=Lewis County, Washington | website=official website | url=http://lewiscountywa.gov/weedcontrol/wsu-agweathernet-a-tool-to-plan-and-manage-farm-operations-2 | access-date=2018-03-06 | archive-url=https://web.archive.org/web/20180306142332/http://lewiscountywa.gov/weedcontrol/wsu-agweathernet-a-tool-to-plan-and-manage-farm-operations-2 | archive-date=2018-03-06 | url-status=dead }}</ref> The Oregon Hop Commission funds three sensors in northwest Oregon.<ref>{{citation|title=Financial support|work=AgWeatherNet official website|publisher=Washington State University|url=http://weather.wsu.edu/?p=90350|accessdate=2018-03-05}}</ref> Several [cranberry](/source/cranberry) farming concerns fund a sensor at [Grayland](/source/Grayland%2C_Washington) on the Pacific Coast.

The system began in 1988 with the name Public Agricultural Weather System (PAWS).<ref>{{citation|title=WSU has 135 weather stations in farming communities|date=April 1, 2011 |publisher=[KNDO-TV](/source/KNDO-TV)|location=[Tri Cities, Washington](/source/Tri_Cities%2C_Washington)|url=http://www.nbcrightnow.com/story/14369507/wsu-has-135-weather-stations}}</ref>
