My research is centered on the observation and analysis of weather and climate processes in mountainous regions. My current research activities include further development of MesoWest and ROMAN (see http://mesowest.utah.edu), which provide access to surface weather observations for operational, research, and educational applications. MesoWest also provides a foundation from which to conduct research to improve data assimilation techniques over complex terrain and evaluate the cost effectiveness of surface observing networks. I also am involved in research related to the Great Salt Lake, Utah regional climate issues, and cold-air pools associated with poor air quality.
