B22A:
Constraining Ecosystem Carbon Uptake and Long-Term Storage with Integrated Modeling, Experiment, and Observation IV


Session ID#: 9055

Session Description:
Terrestrial ecosystems mitigate anthropogenic carbon release by taking up and storing carbon in biomass and soils. A series of model inter-comparisons and data assimilation studies have used eddy covariance measurements to validate and constrain land surface models however decadal and centennial processes are usually poorly constrained by data. Also there are many other data sources which could inform long term carbon storage (primary productivity, biometric measurements, tree rings, paleo-metrics, land use, plant community records, pollen records etc.). This session will focus on both short and long term processes with controlling ecosystem carbon uptake and storage using both modeling and observational approaches.
