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.<br class=""><br class="">This case is run as part of the daily testreport cases and appears to pass on glacier, but I can’t find any STDOUT files to check if the salt sensitivities remain nonzero.<br class=""><br class="">I’m not sure where to look for the source of the problem, so any advice would be appreciated. If anyone has a recent STDOUT file from this test case, I’d be interested in that as well.<br class=""><br class="">Thanks!<br class="">Christopher<br class=""><br class=""><br class=""><br class="">-----------------------------------------------------------<br class="">Christopher L.
