Radiation & Climate (GRS)
Gordon-Kenan Research Seminar

Progress in Understanding Clouds, Water Vapor, Aerosols and Precipitation


July 9-10, 2011


Colby College
Waterville, ME


Mark D. Zelinka

Associate Chair:
Alexandra L. Jones

Meeting Description

The Gordon-Kenan Research Seminar on Radiation & Climate is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas.

The focus of this meeting is on outstanding issues in climate change, particularly those in which the interactions between clouds, water vapor, aerosols, and precipitation play a major role. The Conference will feature a broad range of topics, including grand challenges in atmospheric radiation and climate, cloud and water vapor feedbacks, aerosol-cloud-precipitation-climate interactions across scales, new approaches for remote sensing and in-situ observations of clouds, water vapor, aerosols, and precipitation, and multi-scale modeling challenges.
