Hi, I’m new in Pangeo Cloud. I want to extract Salt and Theta profile time series from MITgcm LLC4320 data using llcreader. But, it takes ~10 minutes to save single profile into netcdf format. Could sb help me speed things up? Thanks.

Are you using the NASA ECCO data portal? If so, there is nothing we can do to speed things up. Data access via the portal is extremely slow.

Thanks Ryan. Is there other convenient way to access vertical profile for a specific site?

Hi, I have the same curiosity as you, may I ask if you get the vertical profile successfully?
