Linkou County fire, 9 November 2022 Linkou County

Out · last measured on 10 Nov 2022

The fire started on 9 November 2022 in Linkou County, China, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,571 hectares from heat detections, spread across a single municipality.

It is the 402th largest in Heilongjiang Province since 2016 (of 1751 with a page). Number 39 in China in 2022, of 241.

We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

The weather day by day

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke

CAMS · Copernicus

On 10 November 2022 the air beside the fire reached 90 µg/m³ of PM2.5. That day averaged 60: 4.0 times the WHO daily guideline (15).

Frequently asked questions

How long did the Linkou County fire last?
GWIS (Copernicus) dates it between 9 November 2022 and 10 November 2022: 2 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,571 hectares (25.7 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Linkou County (2,571 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 12.1 °C, humidity dropped to 28 % and gusts hit 49 km/h. The fire danger index (FWI) reached 9, class Low.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of China (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Emergency number: 119

Satellite cross-check

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

What do you think is wrong?

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 119.

Where this data comes from

The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM3 (Open Data Commons Open Database License 1.0). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
