Event-driven: STORM v4 + CLIMADA Holland H08 · v1.1 · 2026-07

US East Coast — high coastal gust exposure fading inland, Florida to New England

Tropical-cyclone peak-gust exposure from 10,000 years of synthetic storm tracks across all six ocean basins.

What ships

Surfaces + Returns — 0–1 susceptibility and per-return-period peak gust (rp50/100/250/500, m/s).

Every release: 0–1 score · 5-class band · per-pixel uncertainty · input-coverage mask · STAC item · methodology doc.

Inputs

STORM v4 10,000-yr synthetic tracks × 6 basins (Bloemendaal 2020, CC0), CLIMADA TropCyclone wind-field renderer, Natural Earth land mask

Version history

What changed between releases — the same notes that ship with the data. Newest first.

Surfaces

v1.1

2026-07

current

Compact uint16 encoding. The four surfaces (susceptibility, classification, uncertainty, coverage) now ship as compact integer COGs with a documented scale, ~3× smaller than the previous float32 files, with no loss of precision at the delivered resolution. Faster to fetch and tile.
Full-resolution coastline (GSHHG-f). The land mask moved to the Wessel & Smith full-resolution shoreline (~100 m native). Every real piece of land — barrier islands, cays, narrow peninsulas (Wrightsville Beach, Oak Island, Padre Island, the Bahamas cays) — now returns a value instead of falling into a coastline hole.

v1.0

2026-07

Initial event-driven release. Susceptibility derived from STORM v4 10,000-year synthetic tropical-cyclone tracks across all six ocean basins, rendered through the CLIMADA Holland (H08) wind field. This replaced a retired statistical model (Gumbel fit to ERA5 gusts) that conflated tropical and extratropical wind and produced false inland hotspots; geographic correctness is now intrinsic, because storms are only seeded where tropical cyclones actually form.

Returns

v1.0.1

2026-07

current

Coastal-fidelity fix (Carolina Beach class). Coarse-grid gust fields are now dilated into the coastline before the 0.1° → 90 m downscale, so narrow coastal cells no longer drop to nodata. Oceanfront and barrier-island locations that previously read as holes (Carolina Beach, Kure Beach, Oak Island, Wrightsville Beach, the Outer Banks) now carry a finite gust.
Full-resolution coastline (GSHHG-f) and consistent inland fill: locations far from any basin return 0 m/s rather than nodata, so a query over any real land always returns a result.

v1.0

2026-07

Initial release. Per-return-period peak gust (rp50 / rp100 / rp250 / rp500) from STORM v4 10,000-year synthetic tracks × six basins, rendered through the CLIMADA Holland (H08) wind field, with per-cell uncertainty from the spread across the ten independent 1,000-year STORM sub-catalogs.
