East Ujimqin Banner fire, 21 April 2016 China
The fire started on 21 April 2016 in East Ujimqin Banner, China, and satellites saw it burning for 1 day. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,481 hectares from heat detections, spread across a single municipality.
It is the 182th largest in Inner Mongolia Autonomous Region since 2016 (of 370 with a page). Number 73 in China in 2016, of 180.
The power measured by the satellite is low (10.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 4 days without rain (1 mm or more) when it started. Rain came after the fire: 8.0 mm on 22 Apr.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.
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.

Frequently asked questions
- How long did the East Ujimqin Banner fire last?
- GWIS (Copernicus) dates it between 21 April 2016 and 21 April 2016: 1 day 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 1,481 hectares (14.8 km²). It is an estimate: official national figures may differ.
- What was the weather like?
- During the fire the temperature reached 11.3 °C, humidity dropped to 27 % and gusts hit 76 km/h. The fire danger index (FWI) reached 16, class Moderate.
- 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

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.

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.
