One exciting thing from over the holidays is that the Int'l Civil Aviation Organization (@ICAO) and aircraft engine manufacturers for the first time publicly released quantitative emissions indices for particle # and mass emitted per unit fuel burn! 🧵 1/… Scatter plot of aircraft engine non-volatile particle number Up until now, certification data for aircraft engine particle emissions have been reported in terms of a "smoke number", which is derived from the change in reflectance of a Whatman 4 filter after collecting 16.2 kg/m² exhaust. 2/… Pictures of smoke filters with large reductions in particle

Excited to be in #AGU20’s tutorial on #MachineLearning for #Geoscience today with over 1200 registered participants from across the world! First time I'm hearing about the Zarr data format for breaking large datasets into a large number of small binary files that are good for cloud storage.

Just getting around to watching the many excellent #AGU20 talks on the atmospheric effects of COVID-19-driven societal changes. While I would've liked to have attended the live sessions, I am loving watching these on demand at 1.5-2x speed. A few highlights (of many) in a thread: Greg Frost presents a scientific smorgasbord of @NOAA's COVID AQ research in the United States over recent months. Measurements and fuel-based inventories show significant reductions in motor vehicle emissions that are confirmed by satellites.…
