NASA Space Apps 2026 · Fire records, harmonized
Twenty-three years of fire, one calendar.
Aqua/MODIS and Suomi-NPP/VIIRS do not agree. NinaCal brings both onto one detected-hotspot-day scale from 2003 to 2025 — with a NOAA-20 bridge for selected outages — on a 0.05° grid you can explore country by country.

From raw detections to a readable calendar
- 01
Aggregate
Screened satellite observations are grouped by 0.05° cell and month. The value counts detected hotspot-days — not raw pixels or individual fires.
- 02
Harmonize
Aqua/MODIS hotspot-days are converted to the Suomi-NPP scale. NOAA-20 fills selected outages; the model and its error are shown in the console.
- 03
Read
Draw a country, box or polygon. The API filters published cell centres, respects source availability, and returns one aggregate for every chart and export.
02 — what you get
Built for the questions people actually ask
Which months burn most?
A year × month heatmap over the whole record, with an accessible ramp and the exact numbers one click away.
Is this month unusual?
The latest month against the median of the same month in previous years, with a robust standardized anomaly.
Can I trust the 2012 seam?
Cross-validation WAPE, RMSE and the chosen calibration are published in the mission-control validation panel.
Can I take the numbers?
Export harmonized hotspot-days per 0.05° cell and month as CSV, generated in the browser with no account and no backend.
03 — open by construction
One row, one cell, one month
The v2 bundle stores monthly hotspot-day data in a compact columnar format. The formal contract and caveats live in the repository beside the data.
- Sparse absence means zero only inside published cell support and an available month; unavailable sources stay unknown.
harmis detected hotspot-days on the Suomi-NPP scale — not a fire count and not burned area.- Early years are Aqua/MODIS estimates; later years use Suomi-NPP or selected NOAA-20 fallback months, all on one scale.

The map, the calendar and the evidence in one room.
A dark globe with 0.05° cells, an orbitable camera, a looping 2003–2025 timeline, any-country comparison and the model evaluation — all in one instrument.
