# Janice Coen

Janice Coen is a Project Scientist at the National Center for Atmospheric Research in Boulder, Colorado. Her work focuses on understanding and predicting wildland fire behavior through the use of wildfire modeling software. She has made major contributions to the field through her coupled weather—wildland fire computer simulation models.

## Education

Janice Coen graduated magna cum laude from Grove City College in 1986 with a B.S. in Engineering Physics. She then went on to receive her M.S. and Ph.D. in the Department of Geophysical Sciences of the University of Chicago in 1988 and 1992, respectively.

## Career and research

Since 1993, Coen has held various positions at the National Center for Atmospheric Research (NCAR) in Boulder, CO. Since June 2018, she has been a Project Scientist III in the Mesoscale and Microscale Meteorology Laboratory of NCAR.

Coen studies wildland fire behavior from a variety of perspectives, but the majority of her research over the last 25 years has advocated for the utility of wildland fire modeling software. Wildfire simulation models are generated by collecting a myriad of data such as fuel load/moisture, wind speed, temperature, pressure, topography, etc. and leveraging those data to simulate wildfire behavior to aid in wildfire suppression. Coen has developed two coupled numerical weather prediction – wildland fire behavior models that have become widespread in the research community and transformed how people interpret fire behavior.

Coen's current work focuses on large wildfire events and the use of weather-fire modeling software to better understand wildfire behavior.

Coen's 2005 Coupled Atmosphere Wildland Fire-Environment (CAWFE) model represents the most advanced modeling systems in use today. The CAWFE model combines a numerical weather prediction (NWP) model with a wildland fire behavior module. This model was created to better account for interactions between the unique weather (extreme wind conditions, fire whirls, fire tornados, horizontal roll vertices, pyrocumulus) and behavior (e.g. flanking, running, backing) endemic to wildland fire.

CAWFE incorporates data from the three main environmental factors that affect wildland fire behavior: weather, fuel characteristics, and topography. Unlike other models such as BehavePlus and FARSITE that treat these three pillars as independent phenomena, CAWFE accounts for the fact that there are interactions and feedbacks between these three predominant factors (e.g. topographic influences on fuel moisture with variance in elevation, aspect, etc.). CAWFE explicitly considers the feedback mechanisms between atmospheric dynamics and fire behavior over time, and it remains the most capable modeling tool to predict a fire's intensity and spread.
