Every pass this season · pick A and B
Sentinel-2 L2A true color, read at 20 m. One pixel is 0.04 ha. A strip narrower than about 40 m can hold skiable snow and show nothing. By mid-September, north-facing cirques sit in shadow at the late-morning overpass, so one zero isn't proof of anything.
How we got to this status
- The Sep 24 pass was cloudy over the site (100%), so a cloudy pass counts as no look, not as zero. This uses the Sep 12 pass.
- Sep 12 pass fully covers the site and is clear over it.
- No snow pixels in the window (under 3 px counts as zero).
- Not flagged as possible new snow.
- A second clear zero in a row (after Sep 4), so it reads Gone.
- A ground report from Sep 24 is less than 10 days old, so it's shown first until Oct 4.
