Investigating the role of Sea-Surface Salinity (SSS) in simulating historical AMOC decadal variation

This new study aims to advance decadal prediction models by exploring regionally-dependent coupled sea-surface dynamics at work in the Atlantic and Pacific in initialized prediction ensembles.

Reaction of ⍺-pinene with nitrate is a major contributor in secondary organic aerosol formation 25 February 2022

Reaction of ⍺-pinene with nitrate is a major contributor in secondary organic aerosol formation

New research reveals the contribution of ⍺-pinene + NO3 in the secondary aerosol budget, and likely constitutes a major removal pathway of reactive nitrogen from the lower troposphere.
