About the data

Prediction and reference, together

StormSense is a retrospective case-study viewer, not an operational forecast product. Nowcast shows inference at observation time; Forecast shows deterministic retrospective validation at a fixed +12-hour lead. In Forecast animation, map time is the issue time and the blue highlighted point is valid 12 hours later. The MLP is the maintained +6-hour scalar model applied recursively; ConvLSTM is an external inference artifact.

The highlighted Nowcast series is derived from the selected inference artifact. ViT is an imported comparison artifact. For UNet+MLP, Maximum wind is the corrected scalar while the remaining diagnostics come from the upstream UNet wind field. The selector does not change the map or summary cards. The cream reference on Maximum wind is retrospective IBTrACS maximum sustained wind, with its classification shown in the hover details. Optional NWP full-track series appear as muted dashed lines.

SAR wind is a radar-backscatter retrieval rather than uncertainty-free truth. All SAR swaths share a fixed 0–60+ m/s (0–116.6+ kt) scale. PMW imagery uses the comparable vertically polarized 89–92 GHz band from AMSR2, GMI, and SSMIS. PMW and geostationary imagery use distinct color maps because they represent different physical measurements, while each retains fixed 190–292 K bounds; PMW no-data pixels are transparent. Use the map layer toggle to show or hide all fixed-scale CMI_C15 geostationary images together. Gray chart dots mark matched SAR retrievals; dashed lines interpolate visually between sparse acquisitions.
