Short summary
Using aircraft data collected over the Atlantic Ocean, we discovered that new particles form regularly in marine air at two different heights, challenging the belief that sea salt prevents this process. These particles can grow to form cloud droplets, affecting Earth's climate. We found particles forming at two heights: where upper atmosphere air enters the ocean boundary layer and where the well-mixed surface air meets the stable air layer above. This discovery will help improve climate models.
