This document synthesizes insights from the NASA CMS (Climate Modeling System) uncertainty working group, aided by contributions from participants like Chris Badurek and David Baker. It focuses on the challenges of understanding uncertainty in ocean/air, ocean/land, and land/air fluxes as discussed in the November 2013 meeting at JPL. By addressing model-data comparison and types of uncertainty, the goal is to harmonize results, foster collaboration, and improve predictions. The information is crucial for enhancing climate models and observational accuracy.

If we were all talking about the same thing, then we could put all of our results together and everything should overlap! What is uncertainty here? Model Data Map of state or flux Observation Propagation Map 2 of state or flux NASA CMS Nov 2013 JPL
