Loss of the aging ACE-FTS and MLS satellite instruments will create a “data desert” around stratospheric composition, suggests a paper by @rosssalawitch.bsky.social et al in #BulletinAMS. Observation gaps may hinder understanding of climate change.

The 2024-2025 polar vortex season is wrapping up with an interesting "final stratospheric warming" event. Read more on the NOAA climate.gov blog today!

Yay! Thank you.

I've made a starter pack of people who work on the stratosphere/middle atmosphere and/or often post about the stratosphere, including forecasts of the polar vortex.

Please do suggest anyone I've missed – quite hard to keep up with everyone on here now!
