Continuous subglacial lake detection in Antarctica

[weiji14]

Find new active subglacial lakes in Antarctica automatically when new ICESat-2 datasets are available!

Processing Pipeline:

• Step 1. Setup a scheduled Continuous Integration service to detect when new data releases are available
  • Ping https://n5eil02u.ecs.nsidc.org/opendap/hyrax/ATLAS/ATL06.003/catalog.xml or alternative source to get latest date
  • Look at using intake-thredds or siphon or jupyterlab_thredds
  • 👋 Need help figuring out how to authenticate to NASA URS without exposing personal credentials
• Step 2. If new data found, run the data processing pipeline
  • I.e. atl06_to_atl11, ..., atlxi_dhdt.py
  • 🤔 How to only run only a 'diff' between data releases instead of everything?
• Step 3. Generate maps of new subglacial lake locations
  • Will need to run some cluster analysis, generate hydropotential contours, do image differencing, or something along those lines
  • Include metadata information such as estimated lake area/volume, amount drained/filled, etc
  • ❓ What other remote sensing information might help with this, and what should the output look like?

Open to ideas/suggestions, especially on the points with emojis above ⬆️.
