Welcome to the homepage of Professor Tristan L'Ecuyer and the Atmospheric Radiation and Climate Research Group in the Department of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison. Our research seeks to improve climate predication by better understanding the processes that govern atmospheric energy balance and the global water cycle. We believe this can only be achieved by combining state-of-the art remote sensing tools, innovative analysis of satellite datasets, coordinated regional field projects, and numerical modeling. Take a minute and get to know who we are, look through our publications, explore our projects and datasets through our research portal, and read our latest news.

Research Interests: Earth's Energy Balance, Cloud-Aerosol Interactions, Climate, Model Evaluation, Satellite Remote Sensing, Ground Validation

Prospective Students and Interested Researchers
We are seeking energetic individuals interested in pursuing careers in statellite remote sensing and global climate to join our dynamic research team. Motivated students at either the MS or PhD level and qualified post-docs are encouraged to contact us for more information.
