•Goal: Provide
global land surface initialisation states for
the retrospective period of 1979 to present.
•A two-tiered approach.
•Tier
1: Spin-up the land surface model
off-line from the GCM using the best
atmospheric forcing data available. Minimises forcing bias!
•Tier 2:Assimilate passive microwave remote sensing observations of near-surface soil moisture from SMMR and SSM/I. Minimises
model and forcing bias!
