Recap:

• Major differences of NISAR compared to Sentinel-1 (main land polarization mode = HH, left-looking, ascending pass = local dusk)

• Motion to focus on some particular data products and locations (1 Greenland glacier cc @cjense , 1 snow field for GCOV @egagli, 1 landslide in Cascadia region (@scottyhq / @gbrencher)

Open questions (anyone feel free to chime in :):

• Why did NISAR opt for HH instead of VV as primary land polarization mode?
• What is best approach to streaming data rather than downloading entire file first?

Discussion:
Q: Why are people not using opensarlab?
A: Home directory automatically wipes after period of not using :(

Q: Should we have a community software package like icepyx? or what would be a way to facilitate using cloudbank resources to simplify working with NISAR data?

• We don't want to create yet another repository full of notebooks. But could be an installable library? Or a RAG bot? Or a batch workflow via CloudBank resources? Or focus on adding documentation via PRs to https://nisar-docs.asf.alaska.edu ...
