Derek "Deke" Arndt Derek Arndt joined OCS in 1994 as a graduate student, and became a full-time Climate Information Group staffer in 1996. His research and service efforts center around using the best data and latest science to help Oklahomans make better climate- and weather-sensitive decisions. To supplement the CIG service mission, Derek writes the "OCS/Mesonet Ticker", a daily e-publication of OCS. It was originally launched in 1998 to provide updates during a severe flash-drought. Since then, the Ticker has evolved to present developments in science, research, emerging climate issues and interesting weather phenomena to a wide audience. Ticker subscribers range from 2nd-grade students to media outlets to college professors to members of the U.S. House of Representatives. During his first years at OCS, Derek worked on the foundation of the Oklahoma Mesonet's quality assurance system. He also implemented many of the Mesonet's first pest and disease models for agriculture. In recent years, he has lectured for OCS's educational outreach programs, where participants range from public safety officers to K-12 teachers to energy industry decision-makers. Derek provided leadership for OCS's "Mesonet 2002" international symposium of June 2002. In 2003, he completed five years of research support for the implementation of the world's first "smart" geothermally heated bridge, designed to prevent preferential bridge-deck icing. From 2004-2007, Derek served as program manager for OK-FIRST, Oklahoma's award-winning public safety educational outreach program. Derek's web efforts involve weaving Oklahoma Mesonet data into traditional weather products, including forecasts, guidance products and climatological normals. This type of context will be necessary for full inclusion of regional mesonet data into the national mainstream. His Oklahoma drought tools provide a comprehensive on-line monitoring center for Oklahoma's citizens and decision-makers. Derek holds a B.S. and M.S. in Meteorology from the University of Oklahoma. His M.S. Thesis, "The Lasting Effects of Mesoscale Convective Systems Over Eastern Oklahoma in 1994", dealt with land-atmosphere interaction and the distribution of surface energy processes. His primary research interests are applied climatology, particularly concerning drought and land-atmosphere interaction. He is also a student in the University of Oklahoma's Adult & Higher Education Ph.D. program; his research focuses on adult education and development.
