Hello all,
I am assimilating XBT, CTD and ARGO T & S Met office observation data using I4DVAR. I have generated one super obs file containing all these observations.
Now I want to test the impact of assimilating only ARGO Temperature. So I set the parameters in s4dvar.in as follows:
Code:
bgqc_type == 2
Nprovenance == 5
Iprovenance == 3 4 5 6 7
P_bgqc == 0.0d0 0.0d0 0.0d0 4.0d0 0.0d0

I understand that this setting will let only the ARGO temperature (corr. to Iprovenance=6) be passed for assimilation and other obs be rejected.
But the 4DVAR still assimilates all the obs as in the previous case where I set
Code:
P_bgqc == 4.0d0 4.0d0 4.0d0 4.0d0 4.0d0

Is something I understand wrong about this quality control of observations?
