[MITgcm-support] Can't replicate verification/global_oce_cs32/ad.sens

[gael forget]

Hi Christopher,
I attach this morning’s STDOUT below. I just checked that adxx_salt.0000000000.data is not filled with zeros in the GLACIER3.MIT.EDU run.
Cheers,
Gael

While there are some differences related to the different model versions (66c for the included results compared to my 67b setup), most of the AD results are similar to within a couple of decimal places. The only weird thing in my case is that all the salt sensitivities are ZERO: all the ad_dynstat_adsalt fields are zero and the ADJsalt files are zeros. The adxx_salt file is written, but is zeros as well. I have verified that salinity is specifically included as a generic control in data.ctrl and the xx_salt file is written at the beginning of the forward run, so I’m stumped.
