Enviro
-weather Mission
Enviro-weather is an interactive information system linking real-time weather data, forecasts, and biological and other process-based models for assistance in operational decision-making and risk management associated with Michigan’s agriculture and natural resource industries.Slide3
System Basics
8 Full- and part-time staff77 automated weather stations across MI and WIDedicated computer system for collection, processing, dissemination, and archival of data
System supported by MI Project GREEEN, MI AgBioResearch, MSU Extension, external grants, corporate/individual sponsorships, and grower contributionsSlide4

Weather Monitoring
Variables monitored include air and soil temps, rel. hum., precip., solar rad., wind speed and dir., leaf wetness, and soil moisture
Network utilizes cell IP modemsObs. available at 5 min., 1 hour, and 24 hour intervals New sites sponsored by grants, grower contributionsSlide8Slide9Slide10
Adding New Products
Enviro-Weather system is modular in design to accommodate new productsPotential new products identified by work groups or staff/facultyProduct check listMethod based on sound science
Method tested/validated under Michigan or similar conditionsMethod usable with Enviro-Weather data, systemSlide11

How has using
Enviro
-weather products changed the amount of time required to manage your crop during an average work-week during the growing season?
Quantifying the impact on work hours based on $15 per hour for all apple, tart and sweet cherry growers, this amounts to a per grower savings of 750 work hours and $11,250.Slide22

Impacts are based on rates of adopting EW by commodity and average experienced yield impacts by commodity
Does not account for quality impacts, which tend to exceed those of yield
Michigan production increases by 7 million
lbs
Michigan sales increase and costs savings result in statewide economic impact of $1,786,000Slide23
Future Directions
Continued research, new product developmentConversion of dataloggers (CR10X to CR1000)Revenue generation (value added apps, e.g. smart phone)
Increasing use of NWS gridded productsReal time obs. (RTMA)Forecast products (NDFD)Inclusion of climatological statistics in system productsSlide24Slide25Slide26
SummaryDemand for detailed weather information in IPM is increasing
Weather-based applications have large potential economic and environmental valueSustainable funding mechanisms still needed, including grower contributionsSlide27
