At a glance
Latest reading and this season’s headline numbers for the selected block.
Season curves
Every season on a shared April–October axis, outlier-screened and
smoothed (Savitzky–Golay) so residual cloud and smoke spikes don’t read as vine
stress. Toggle years in the legend (it drives both charts); hover for values and dates.
The freeze year is red; exact scene readings live in the baseline chart and the CSVs.

Current season vs baseline
The latest season against its own prior-season, day-of-year baseline.
Red dots mark flagged (two-in-a-row below the 10th percentile) readings.
Season outlook machine-learned projection
A Gaussian-process model trained on this block’s prior vine seasons
(plus the season so far) projects NDVI through October. The shaded band is the model’s
80% range — it reflects how much past seasons varied, and it cannot see weather ahead.
With only a season or two of vine history, treat it as provisional.
This season across blocks
All blocks together, smoothed like the season curves: if every curve dips
at once the cause is shared (weather, heat, smoke); one curve dipping alone points at that
block (irrigation, virus, damage).
Current vigor zone
The most recent complete-season vigor map for the selected block,
one square per 10 m pixel. Zoning needs a full April–October season, so a new map appears
here once each season ends. Low-vigor zones are where the vine was weakest —
check those rows first on the next walk. Hover a pixel for its season-mean NDVI.
Vigor zones by season
Within-block zones on the real block outline, one square per
10 m pixel. Zones that hold their shape across years read as soil or rootstock;
one-off zones read as management, irrigation, or damage. Hover a pixel for its
season-mean NDVI.
Long-term history Landsat 8/9 · 30 m · since 2014
Growing-season (May–September) mean NDVI per year from Landsat —
a different satellite at coarser resolution, so compare shapes across years rather than exact
values against the Sentinel charts above. Years before the 2024 planting show the previous
ground cover; the 2021 heat dome and the 2024 freeze year sit in this record. Hover a point
for the number of clear scenes behind it.

Blocks planted in 2024, so seasons before then reflect the previous ground cover;
baselines and “typical” comparisons respect each block’s baseline_start.
