- With this release it is possible to indicate that it is ok to have missing values
- in the state vector. There is a namelist item <em class=code>allow_missing_in_state</em>
+ With this release there is limited support for this in DART. There are still
+ serious questions about what the correct results should be if the ensemble
+ count for some state vector item is smaller than the total ensemble size.
+ Nevertheless, with this release we have implemented support for missing
+ state vector values in the CLM Land model.
+ There is a new namelist item <em class=code>allow_missing_in_clm</em>
in the &assim_tools_nml namelist. Setting this to .true. will allow DART to
avoid updating any state vector items in which one or more of the ensemble members
- have a missing value. Inflation cannot be enabled with this option, and all
+ in CLM have a missing value. Inflation will be disabled for any state vector
+ items where one or more ensemble members have missing values. All CLM
forward operators must test for and be prepared to return with a failed forward
- operator code if any of the values it requires are missing.
+ operator code if any of the interpolation items it requires are missing.
