Vegetation Loss From Hurricane Helene
What it measures. Shows where plant cover was stripped away after Hurricane Helene, comparing current vegetation to past years to flag the biggest losses.
How it's made. From Harmonized Landsat and Sentinel-2 (HLS) satellite imagery, which blends NASA and European satellite views.
How & where you'd use it. Helps responders spot landslides and severe storm damage by where greenery suddenly disappeared.

Official description
Difference between historical and current year observed vegetation cover at the date of maximum decrease (vegetation loss of 0-100%). This layer can be used to threshold vegetation disturbance per a given sensitivity (e.g. disturbance of ≥20% vegetation cover loss). The sum of the historical percent vegetation and the anomaly value will be the vegetation cover estimate for the current year.
