Our staff and associates

Jeff Andresen, Professor of Meteorology/Climatology in the Department of Geography, the State Climatologist for Michigan, and director for the Enviroweather Program. His research and extension interests focus on weather and climate on agriculture, especially within Michigan and the Great Lakes Region. Current and past themes include; climatological trends and potential impacts, water use for agricultural irrigation, potential future changes in climate, and weather and risk management in agricultural production and plant protection.

Keith Mason, Enviroweather Coordinator. Keith facilitates and helps manage the various projects within the Enviroweather program. He serves as liaison between MSU researchers, MSU Extension, Enviroweather staff and its partners, supporters and users. Keith also works with agricultural and horticultural industry representatives to identify and implement Enviroweather projects that align with commodity needs. He also works to educate users about Enviroweather tools, while working to identify new users and areas for expanding resources. Keith comes to Enviroweather with almost twenty years of experience in Integrated Pest Management working as a research assistant in the Department of Entomology at Michigan State University. During that time Keith coordinated several multi-state, on-farm research/extension projects in grapes and blueberries. You can reach Keith by phone at (517) 432-6520 or email at

Tracy Aichele, Steve Casey and Jim Brown work on the computing systems behind the scenes. Jim specializes mainly on server and database administration, keeping the systems running smoothly. Tracy and Steve build and maintain the Enviroweather website and program the Enviroweather reports and models.

Steve Marquie manages the field operations of the weather station network and coordinates maintenance and repair. He designs and implements new weather monitoring systems, provides technical resources for workgroups and users on data logging, remote measurements, and field GPS/GIS technology. You may reach Steve by phone at (517) 355-8128.
