Sulfuric and nitric acids drive iron dissolution differently
Iron dissolution in urban aerosols follows divergent pathways controlled by sulfuric and nitric acids, shifting from nitric acid dominance at ground-level to sulfuric acid in the upper atmosphere.

Dust layer weakens low-level cloud increase over the North Atlantic
Study quantifies how free-tropospheric Saharan dust over the North Atlantic modulates low-level cloud cover via longwave-induced cloud-top warming that counteracts shortwave-driven cloud enhancement.
