I have experienced that the Nonlinear cost function is not being calculated in a 4D-PSAS application when the VERIFICATION cpp is activated.
Hence the variables NL_iDataPenalty and NL_fDataPenalty are zero in the resulting ocean_mod.nc file.

I learned that VERIFICATION is only to be used for runs without assimilation, logically. Using this option in PSAS (and possible also IS4DVAR R4DVAR) will not throw an error or warning, unfortunately.
