2017 GDAP-EEI Meeting

Oct 9 - 12, 2017 | Mesa Lab, NCAR, Boulder, CO, USA

GDAP-EEI Meeting
NCAR, Boulder, Colorado
Damon Room, Mesa Lab

The draft agenda for the meeting is below.

9 October 2017

Location: Damon Room, Mesa Lab

Topic: Interactions within WCRP with CONCEPT-HEAT

CONCEPT HEAT – GDAP members welcome


The CLIVAR research focus CONCEPT-HEAT (Consistency between planetary energy balance and ocean heat storage) is focused on Earth’s Energy Imbalance (EEI) and its largest component, the changes in ocean heat content (OHC). CONCEPT-HEAT aims to bring together experts from ocean and atmospheric reanalysis, air-sea fluxes, OHC, atmospheric radiation, sea level, and climate models to better synthesize all the information available. A goal is to foster collaboration among these different communities and build up a multi-disciplinary community to promote progress and an integrated view.
