Jennifer E. Kay
My research interests include: 1) cloud and aerosol processes and their influence on the coupled climate system, 2) polar climate feedbacks and mechanisms for recent Arctic sea ice loss, and 3) evaluation and improvement of climate models using data assimilation and satellite observations (especially CloudSat+CALIPSO). I am NCAR's COSP/CFMIP contact, and am also a co-chair of the CESM Polar Climate Working Group. Clara Deser and I are co-leading the CESM Large Ensemble Project. In January 2014, I will be starting as a tenure-track assistant professor at the University of Colorado at Boulder: Kay Group Website.
