Global total estimated fire emissions were the second-lowest in the 24-year CAMS dataset for September 2026. However, Indonesia recorded its third-highest September monthly total estimated emissions, contributing to Asia having the highest estimated fire emissions of any continent.

Behind every weather forecast lie millions of observations gathered from satellites, aircraft, ships, buoys and other instruments.

ECMWF monitors these instruments throughout their lifecycle, from their rollout and evaluation through to their retirement.

2026 cumulative daily total fire emissions for Indonesia to 30 Sept continue to keep pace with previous El Niño years of 2015, 2019 & 2006. #CopernicusAtmosphere GFASv1.2 data available via Fire Emissions Watch apps.atmosphere.copernicus.eu/fire-emissio... @copernicusecmwf.bsky.social @ecmwf.int

Scientists found evidence for wildfires that burned only around 560 miles from the South Pole 90 million years ago, making them the southernmost fires ever documented.

Dovrou & Voulgarakis (2026) explore our current understanding of the chemical reactions within #wildfire smoke plumes. 🔥

In @eos.org, we asked the lead author to give an overview of fire plumes, how scientists study them, and future directions for research.

Ozone pollution is interlinked with our climate, health, ecosystems & food production. During the first eight months of 2026, almost 40% of the global population was exposed to extremely high ozone levels, including 60% of people in Asia. 🔗 atmosphere.copernicus.eu/air-quality/...
