Earth System Models

• Uncertainty in carbon cycle feedbacks stems from structural, parameter, initial conditions and boundary conditions uncertainties
• Data provide both detailed site-based process information and spatial measures of pattern and process that can be integrated into an earth system model
• What would be the essential components of such a system?
– Datasets for evaluation – common measurements, post-processed and saved in common formats served from a CI optimized for interaction with ESMs
– Data products commensurate with model grid cell scales (i.e. FLUXNET GPP product)
– Long-term and accurate to observe trends beyond inter-annual variation
– A interoperable (and common?) model capable of simulating coupled land, ocean, river and atmospheric processes
– A data assimilation system capable of ingesting observations (in real time) to improve model performance

Planned DeliverablesSurvey and integrate – Observations (notebooks), Spatially explicit
– Hemispherical Photographs, Spatially explicit– Phenological Camera, Temporally explicit
Data fusion (assimilation) – Community Land Model
Proof of concept – Sites with contrasting phenology– Daily estimates– Annual Time series (?)– Validation activities (?)
