Does Matthis dataset work? Can we use SSH obs to derive geostrophic currents in real-time?

MatthisAuger commented 2 months ago

Hi I just noticed that issue here.

There won't be SSH obs available in real time, as SSH in seasonally ice-covered regions requires multiple post-processing steps that are not available in near real time.

However, past record can be used to know what to expect in terms of geostrophic currents during the voyage. I'm working on a script that uses the stations locations and plots the climatology of U and V from observation at that location, as well as time series showing the current variability over the period of interest (Feb - Apr) over the 2013-2021 record.

Here is an example for one station here. If there is any interest in such diagnostics, I'll clean the code and upload it here. Please tell me if you have any other plot ideas where the satellite record could be useful.

The script is online: Station_obs_SSH.ipynb.

It can be used for each station (will only give variability if the station is at an ice-shelf free location). I'm open to suggestions for any changes.
