I'm very pleased on behalf of co-authors to be able to share this, just published, paper summarizing the @bburnedscience.bsky.social Fire Emissions Workshop in Nov 2023. MODIS has been critical to fire emission estimation for the past two decades & the paper reviews 9 widely used emissions datasets.

Huge dust storms in Pakistan, seen by the @esa.int / @ec.europa.eu Sentinel-2B and Sentinel-3B satellites on 4th November.
Neither satellite was designed to monitor dust plumes, so it's impressive how much information they give us about the detail and extent of these storms!
