This WaPo article by @karishma__m__ highlights some of our work over the last few years on NW India's agricultural fires, a seasonal and episodic source of regional air pollution. These anecdotes from farmers are especially important. #fires π₯ #AirPollution π¨ #India

As Delhi reels once again from toxic air, a story about a law from 16 years ago that tried to adapt to climate change, but ended up exacerbating a climate disaster.
How shifting the rice season unintentionally added to Delhi's air problems.

I had also created an #EarthEngine App to visualize NOAA's HMS smoke π¨ and fire π₯ products. You can check out the app from link below; additional details are in my GitHub repo.

We compared HMS to airport and EPA observations and HRRR-Smoke model estimates of surface smoke. In particular, inclusion of light-density HMS smoke may indicate aloft smoke, leading to overestimates in smoke days and smoke PM2.5.

Our paper on an algorithm for hourly fire π₯ tracking of large wildfires is available as a preprint on ESSD discussions. We tested our GOES-based algorithm on a set of 28 large wildfires in California and derived hourly perimeters, active fire lines, and fire spread rates.

During Canadaβs record-breaking 2023 fire season, NASA scientists tracked the blazes with a new system, FEDS, that uses @NOAA & @NASA satellite data to provide more frequent monitoring of fire activity, growth, and behavior than was previously available. go.nasa.gov/3Sc6Wf4

Important new preprint from @TheRealPyroTina ( friends) showing that the widely-used Hazard Mapping System (HMS) smoke product π₯ is unreliable outside of the Western US. HMS has been used to study smoke in the East which should be reconsidered. Link below:
