[ecco-support] Downloading OCCA data -- FTP link broken

[MIT]

Hi Geoff

For OCCA (& ECCOv4r1,2) files you can get them from the dataverse archives. I built convenience functions in OceanStateEstimation.jl to select and download files.

(The dataverse urls for occa & eccov4r2 are in the repo)

Under the gdcc org you’ll find dataverse.jl , pydataverse, etc

https://github.com/gdcc/Dataverse.jl#readme

Sorry about all the broken links on the Ecco site. almost all of the estimates listed under products have been unaccessible for more than 6 months.

 I have been bringing this up to folks on the MIT & ECCO sides about these issues regularly. But not enough as it seems …

Thank you for reporting this & your understanding.

Best,
Gaël

I have a NASA Earthdata Account (e.g. for accessing ECCOv4r4 data), but I have not found OCCA data on that ECCO Drive. I use OCCA data myself as a useful test dataset for developing algorithms, and I maintain a Python package that uses OCCA data for running an example calculation: see https://github.com/geoffstanley/neutralocean/blob/main/neutralocean/examples/load_OCCA.py, which used to automatically download two OCCA files, but now throws an authentication error.

Ideally, OCCA data can be downloaded without having to sign up for an account, which makes my script much easier for users to run. If a user does need to create an account to get OCCA data, is it allowed (legal) for me to upload these two OCCA files to a permanent file hosting service like Zenodo or Figshare?
