Climate Patterns ViewerDST Now Available 


The U2U team recently launched a new product that shows how the El Niņo Southern Oscillation (ENSO) and Arctic Oscillation (AO) have historically affected climate conditions and crop yields across the U.S. Corn Belt.



  • Customized maps to show when, where, and by how much ENSO/AO phases tend to influence monthly temperatures and precipitation
  • Compare monthly climate values for the entire year in simple, location-specific charts
  • Use the maps and charts to see how ENSO/AO years tend to increase or decrease yields in your area

Summary of U2U Social Science Research   

A  summary some key findings from the U2U Social Science Working Group is now available. This document includes results from two large-scale surveys of Corn Belt farmers and advisors to inform the development and dissemination of climate-based decision support tools.

Researcher SpotlightResearcher


Dr. Chad Hart is an Associate Professor and Extension Economist at Iowa State University. He has worked for many years on issues related to agricultural marketing, agricultural policy and risk management.


As co-investigator on the U2U project, Chad is responsible for coordinating outreach and dissemination. He is heavily involved with promoting U2U decision support tools to agricultural advisors and farmers in the Corn Belt. Chad also plays a critical role in U2U tool development by ensuring our educational resources and products have real-world appeal.


In his spare time, Chad enjoys hanging out with his children (usually losing at video games to them), going to baseball games, and running for fun and (in his case) needed exercise. Working on U2U fills a niche in Chad's interest, as he has always been fascinated with the weather and he jokes that his "backup" career would have been to be a meteorologist.

A new academic year is about to begin and with that comes changes for the U2U team. Several of our students have graduated over the last few months and many postdocs/staff have accepted new positions. We want to take a moment to recognize these important U2U team members who've contributed to this project's continued success.


We wish you the best in your new endeavors!

About Us: 

Useful to Usable (U2U) is a multi-institution research and extension project focused on improving the resilience and profitability of farms in the North Central U.S. amid a more variable and changing climate. Through the development and dissemination of decision support tools, resource materials and training, we strive to transform existing climate information into actionable knowledge for more effective decision making.
