Outline
§The TransCom3 CO2 flux inversion inter-comparison project
§The fully time-dependent T3 flux inversion
§Method (Òbatch least squaresÓ)
§Results
§Methods for bigger problems:
§Kalman filter (traditional, full rank)
§Ensemble filters
§Variational data assimilation
For this one example problem, show how increasing data availability allows one to solve the fluxes at greater resolution.  This, in turn, necessitates more computationally-efficient solution methods.
