 === Description
 
-Adapt observation operator code so that variables are handled as generically as possible in the code, making it easier to add new variables, both surface and profile, with as little hardwired as possible. This will be particularly useful for adding new biogeochemical variables from different models.

-''...''
+Change some of the internal handling of profile observation variables. Currently it's only set up to be able to handle inputs with two variables in, either temperature and salinity, or U&V velocity. This change will remove those restrictions, so that users adding an observation operator for third party biogeochemical model variables will be able to more easily. The changes also add some error checking on the variable names read in from observation files, as currently these aren't checked.
+
+This will require edits to the following modules in OCE/OBS:
+* diaobs.F90
+* obs_oper.F90
+* obs_prep.F90
+* obs_read_prof.F90
+* obs_read_surf.F90
+* obs_write.F90
+
+The following new variables will be added to the &namobs namelist:
+* ln_default_fp_indegs
+* rn_default_avglamscl
+* rn_default_avgphiscl
+* nn_2dint_default [renamed from nn_2dint]
