Who We Are


The State Climatology Office (SCO) is organizationally part of the Atmospheric and Oceanic Sciences Department on the UW-Madison campus. The State Climatology office is located on the University of Wisconsin campus, in Room 1353 of the Atmospheric, Oceanic & Space Science Building at 1225 W. Dayton St., Madison, Wisconsin. Administratively it is part of the Atmospheric & Oceanic Sciences Department, whose chairman, Prof. John Young, serves as State Climatologist, with Dr. Ed Hopkins the Assistant State Climatologist. The office is generally open weekday afternoons, staffed by office manager Lyle Anderson.

As the official state repository for climate records of Wisconsin, the office strives to acquire, archive, process and disseminate weather and climate information particular to the state. The data sources range from original manuscript records to published paper records to digital databases. Many data requests can be answered free of charge, whether by regular mail, phone, fax or email. Where significant time and labor or photocopying is required, a minimal service charge plus costs is assessed.

The Wisconsin State Climatology Office is closely associated with the AOS Department at the University of Wisconsin in Madison. The department consists of 15 faculty and 15 affiliated scientists who teach courses and conduct internationally recognized research in weather and climate. As a past departmental chair, Professor John Young leads coordination and developments with the State Climatology Office.

Current research topics include:

  • global climate systems
  • climate variability, such as El Niño or ancient climates
  • atmospheric interaction with ocean and land
  • biogeochemical cycles
  • global change


Meet the Staff

Director: Professor John Young Director: John Young is a professor in the Department of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison for 40 years, specializing in large-scale atmospheric wind dynamics and turbulence near the earth's surface. These areas are fundamental to understanding the climate system and its variability. He has participated in observational climate programs involving air-sea interaction, monsoons, and the Pacific El Niņo. His work in theory and modeling has concentrated on global-scale wind systems and cloud convection affecting the energy budget of the earth's surface. He is now applying this knowledge to the understanding and prediction of climate fluctuations over the Midwestern U.S. In recent years he has given presentations on El Niņo to professional public groups and the media in southern Wisconsin. He has also served as the departmental chairman.

Assistant State Climatologist: Dr. Ed Hopkins Assistant State Climatologist: Ed Hopkins' area of interest is in Wisconsin's climate, climatic change and science education. He has co-authored a book entitled Wisconsin Weather and Climate (University of Wisconsin Press) with Prof. Joseph M. Moran of the University of Wisconsin-Green Bay. He has contributed to the operation of the State Climatology Office for more than ten years. In addition, he has at least twenty years of experience teaching the introductory level meteorology courses, both at the University of Wisconsin-Madison and at Northern Illinois University. Ed has been actively involved with the education activities of the American Meteorological Society, the American Geological Institute and the National Geographic Society. He has prepared a resource listing of meteorological educational materials directed for elementary and secondary school teachers.

Office Manager and Data Services: Lyle Anderson Office Manager and Data Services: Lyle Anderson manages the day-to-day operations during his office hours each weekday afternoon. He has 18 years of experience assisting the public in this role. He answers basic climate data questions for the public, and in some cases provides actual information from climate records. He also consults with Dr. Hopkins in providing these some of these services.

Assistant Web Programmer: Nicole Schiffer graduated from the University of Wisconsin - Madison's Atmospheric and Oceanic Sciences Department in May 2007. In August 2007 she will begin graduate school at the University of Illinois at Urbana-Champaign. She helped redesign the new website for the Wisconsin State Climatology Office during the summer of 2007.
