Radiation & Climate
Gordon Research Conference

Connecting Observations to Global Circulation Modeling Challenges

Dates

July 16-21, 2017

Location

Bates College
Lewiston, ME Site Information

Organizers

Chairs:
David Turner & Dargan Frierson

Vice Chairs:
Andrew Gettelman & Bastiaan van Diedenhoven

Application Deadline

The application deadline for this meeting was June 18, 2017. You may still submit an application, which may be considered by the conference chair if there is still room available.

Meeting Description

The goal of the 2017 Radiation and Climate GRC/GRS will be to bring modelers and theorists together with observationalists to identify and tackle outstanding questions and significant uncertainties that are present in current global circulation models. The GRC is organized into eight sessions. Each session will start with one or two presentations from a global modeler and/or theorist, which outlines important uncertainties and unknowns in a particular research area (e.g., convective organization, mixed-phase cloud processes, global teleconnections and clouds, etc.). This will be followed by a presentation from an expert in observational technology, which highlights our current capability to provide the measurements needed to address the uncertainties outlined in the previous talk and extrapolates to how future technologies might be brought to bear on the problem. The talks, which will be tightly coupled, will spur discussion on the open scientific questions, the ability of the observations to answer them, and the analysis strategies that will more efficiently couple observations and modeling to advance our understanding of these important uncertainties.

Related Meeting

This GRC will be held in conjunction with the "Radiation & Climate" Gordon Research Seminar (GRS). Those interested in attending both meetings must submit an application for the GRS in addition to an application for the GRC. Refer to the associated GRS program page for more information.
