Spin-up
catchment-based LSM for 1987 using ISLSCP forcing data.

Run
the simulation for 1987 using ISLSCP forcing data and output

surface
moisture data as “observations”.

Assimilated
Data Set
|
|
|
|
• |
Degrade
the soil moisture prognostic variable spin-up states to make the
|

catchments
artificially wet (as for the open loop).
