# Role of methanesulfonic acid in atmospheric particle nucleation and growth

> **Open Intelligence Dossier** · First detected: 2026-06-26 10:07 UTC · Category: Science

## Executive Summary
Plankton‑derived methanesulfonic acid emerges as a key trigger for marine cloud seed formation, reshaping aerosol science.

## Intelligence Brief
Coverage from The Debrief notes the climate relevance; Cyprus Institute researchers are highlighted by multiple outlets (ΚΥΠΕ, Philenews, CBN.com.cy) for overturning decades of cloud formation thinking; EurekAlert! links plankton emissions to the process; CERN’s CLOUD experiment is cited as uncovering a major new source of marine aerosol particles; Nature publishes the detailed role of MSA. Future reports may track how climate models incorporate this MSA pathway and whether further experiments from CERN or other labs test its impact under varying atmospheric conditions.
