 = With data assimilation
 
-The assimilation interface to NEMO is split into three modules. OBS for the observation operator. ASM for the application of increments and model bias correction (based on the assimilation increments). TAM the tangent linear and adjoint model. Please see the NEMO reference manual for more details including information about the input file formats and the namelist settings.

 == Observation and model comparison (OBS) 
@@ -14 +20 @@
 The OBS code can also be run after a model run using saved NEMO model data. This is accomplished using the standalone observation operator (SAO) (previously known the offline observation operator).
 
-To build the SAO use makenemo. This means compiling NEMO once (in the normal way) for the chosen configuration. Then include SAO_SRC at the end of the relevant line in cfg.txt file. Then recompile with the replacement main program in SAO_SRC. This is a special version of nemogcm.F90 (which doesn't run the model, but reads in the model fields, and observations and runs the OBS code. See section 12.4 of the NEMO reference manual.

 == Apply assimilation increments (ASM)
 
-The ASM code adds the functionality to apply increments to the model variables : temperature, salinity, sea surface height, velocity and sea ice concentration. These are read into the model from a NetCDF file which may be produced by separate data assimilation code. The code can also output model background fields which are used as an input to data assimilation code. This is all controlled by the namelist nam asminc. To build the ASM code key asminc must be set.
