The 2019 Gordon Research Conference on Radiation and Climate will be held from July 21 to 26 at Bates College in Lewiston, Maine. The conference will focus on critical topics for radiation and climate science, with a theme of bridging spatial and temporal scales. Because physical processes related to radiation and climate occur on scales from the microscale to the global, and from seconds to ice ages, bridging observations and modeling between such scales is challenging but crucial. Topics of this conference will include ice and liquid clouds, aerosols, climate sensitivity, dynamics, greenhouse gases, and the Arctic.
