[ecco-support] adxx_sst and sss

Hi All,

I've been successfully running ECCOv4 r4 in adjoint mode and generating sensitivities such as adxx_qnet, adxx_tauu. I'm now interested in looking at sensitivities to SST and SSS, and can see from the ctrl package code that it should be possible to add xx_sst and xx_sss as control variables. I've run a short test and I am indeed generating adxx_sst/sss but they are coming out all zeros (other adxx files from the same run are non-zero).

Can anyone let me know if I need to do anything else to get adxx_sst and sss working? I can see from inspection of the code that the ctrl variable contributions are only summed if ALLOW_SS[T/S]_CONTROL are defined but I can't see where these logical variables are set?

Thanks,

Emma
