Atmospheric chemistry

Study reveals tropical isoprene varies by region: Amazonia emission-controlled, Maritime Continent chemistry-controlled, and equatorial Africa intermediate, requiring region-specific atmospheric.

EMAC earth system model accurately simulates global atmospheric hydrogen dynamics, achieving correlation coefficients exceeding 0.9 at remote polar stations against observational data.

21-year satellite inventory shows global atmospheric chlorine declining since 2004, though emerging short-lived substances offset some gains from CFC phase-out regulations.
