5. AgClimate View
Plot local temperature and precipitation variation as far back as 1980,
Track county crop yields and trends, and
Consider crop yields in the context of temperature, precipitation, and growing degree day data
Used in tandem with other decision resources, AgClimate View can help you find long-term correlations between climate trends and yields, while helping you put your recent crop experience into historical context.

13. Corn Growing Degree Days
This tool puts current conditions into a 30-year historical perspective and offers trend projections through the end of the calendar year. GDD projections, combined with analysis of historical analog data, can help you make decisions about:
Climate Risks – Identify the likelihood of early and late frosts/freezes.
Activity Planning – Consider corn hybrid estimated physiological maturity requirements, along with GDD projections when making seed purchasing and other growing season decisions.
Marketing – Look at historical and projected GDD when considering forward pricing and crop insurance purchases.
