Thanks Ou, found it! And the .meta file is the same as input_init<https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/input_init> /xx_diffkr.0000000059.<https://ecco.jpl.nasa.gov/drive/files/Version4/Release3/input_init/xx_diffkr.0000000059.data>meta , right?

Hi Christopher,

One correction to the alternative way I mentioned;
Alternatively, you can calculate it by summing up the first guess of a constant 1e-5 m^2/s (not total_diffkr_r009bit11.bin)and xx_diffkr.dim.0000000129.data.

See Forget et al. (2015; doi:10.5194/gmd-8-3071-2015), Table 1 for the first guess of the mixing parameters.

The description about total_kapredi_r009bit11.bin in the ECCOv4 Python tutorial is incorrect and will be corrected. The field in total_kapredi_r009bit11.bin is the Redi parameter from Release 1, not the adjusted Redi parameter from Release 4.

Hi all:

I’m trying to figure out what the vertical diffusivity field in ECCOv4r4 is, but I’m a little confused about which input file actually contains this data.

On the other hand, the README at https://ecco.jpl.nasa.gov/drive/files/Version4/Release4/input_init/README<https://urldefense.us/v3/__https:/urldefense.proofpoint.com/v2/url?u=https-3A__urldefense.us_v3_-5F-5Fhttps-3A_urldefense.proofpoint.com_v2_url-3Fu-3Dhttps-2D3A-5F-5Fecco.jpl.nasa.gov-5Fdrive-5Ffiles-5FVersion4-5FRelease4-5Finput-2D5Finit-5FREADME-26d-3DDwMGaQ-26c-3D-2D35OiAkTchMrZOngvJPOeA-26r-3DYvEcUc3iPS8v6LXnkXPI-2Dw-26m-3D6Ilpubv4qn3OD41-2D8yhyk6uu5j1XJQRLMfnf7OSEpRQ-26s-3DY5km8rLOIAScTdlOx-2DH4gujN5dag4QnliKlbo22oRnY-26e-3D-5F-5F-3B-21-21PvBDto6Hs4WbVuu7-21fsxdH6il0cs8gPy2j4KkEKbm6gA3GeQz5DpxJVmVJfeEihLVQgSFhGROuiWeWFHJfMg-24&d=DwMGaQ&c=-35OiAkTchMrZOngvJPOeA&r=YvEcUc3iPS8v6LXnkXPI-w&m=nOXKAklfyFn2aPSp4BhLVNBbAX4GgIAPKqUe1AKm844&s=WCDQan_WewifVL3NntyAIn35yg-an_u7Z9T15H1eJVA&e=__;!!PvBDto6Hs4WbVuu7!eilkxLFTGqgTOwu7vR0R-AIvPUW_YKUE-LpaNcpOke9NedgA3IjcHcR9dKusrEkFHeA$> says that  total_diffkr_r009bit11.bin is the "vert. diff. of release 1 (this field plus xx is the total)”, which means that I should add xx_diffkr.0000000129.data to this to get the full diffusivity. However, the values in this file are order 1, so adding it to total_diffkr_r009bit11 would produce diffusivities far outside the expected range.

Using this produces adjustments on the order of 1e-6 to 1e-5, which seems about right. However, the data.ctrl namelist also specifies WC01 smoothing and some thresholding. Do these need to be applied as well?

Is the best way to get this data simply to run the model for a bit and have it dump diffkr? It would be convenient to be able to calculate these quantities without having to run the model, however.

Thanks in advance for your advise,
