Title: Providing the E in G x E x M Abstract: The Iowa Environmental Mesonet (IEM) is an ISU Agronomy project that aims to provide synthesized datasets relevant to support agronomic research and Iowa's Ag Economy. This talk will detail the datasets made available by this project and how they are used by modeling projects like the Daily Erosion Project and Dr Archontoulis's FACTs Project. Finding and understanding the environmental data necessary to support soil science can be extremely confounding. This talk will attempt to demystify available datasets and provide tips for their application. Bio: Daryl Herzmann is a System's Analyst in Agronomy and has worked on the IEM since its founding in 2001. He has a bachelor's degree in Meteorology and enjoys ths apex of physical and computer science.
