| Why assimilate soil moisture? |
||||||||||||||
| • | Accurate soil moisture forecasts are necessary for |
|||||||||||||
| accurate predictions of precipitation. |
||||||||||||||
| • | LSM spin-up does not guarantee correct soil moisture |
|||||||||||||
| initialization. |
||||||||||||||
| • | Errors in soil moisture forecasts result from: |
|||||||||||||
| – | The
memory of errors in LSM soil moisture initialization. |
|||||||||||||
| – | Errors
in atmospheric forcing data. |
|||||||||||||
| – | Errors
in LSM physics. |
|||||||||||||
| – | Errors
in soil and topographic data. |
