Resolves to the bucket containing the Arctic sea ice extent for 2026-11-20 as published by the National Snow and Ice Data Center (NSIDC) Sea Ice Index, Version 4, in the daily file:
- https://noaadata.apps.nsidc.org/NOAA/G02135/north/daily/data/N_seaice_extent_daily_v4.0.csv
- Use the Extent column (million km²) on the row for year 2026, month 11, day 20.
- This is the single-day value, not the 5-day average shown on the Charctic chart.
- NSIDC posts this file with a lag of a few days.
- I'll resolve from the first value that appears for Nov 20, and won't change the resolution for later revisions.
