• Polar meteorology

Dr. Von P. Walden is an Associate Professor in the Geography department at the University of Idaho. Dr. Walden's research interests include polar meteorology and remote sensing of polar clouds and snow, as well as understanding climate change in the western U.S.

He has conducted seven field experiments in the Antarctic and Arctic regions and is preparing to deploy instrumentation at Summit Station, Greenland as part of National Science Foundation’s Arctic Observing Network.

Dr. Walden served on NASA’s Validation Team for the Atmospheric Infrared Sounder (AIRS) from 2001 to 2008. He has acquired funding for a wide variety of research projects, including modeling hydrology of snowmelt-dominated basins, downscaling climate model output, and measuring properties of polar atmospheres. At the University of Idaho, Dr. Walden teaches courses in meteorology, climatology, and global environmental change.

The University of Idaho was recently awarded an NSF EPSCoR Research Infrastructure Improvement grant to study Water Resources in a Changing Climate in Idaho. Dr. Walden led the development of the science team and the scientific portion of the proposal, and is now serving as the Interim Director of Idaho EPSCoR/IDeA.

Dr. Walden frequently gives talks on global and regional climate change to diverse audiences.
