Atmospheric mercury speciation at the Monte Curcio GAW/GMOS high-altitude observatory: A multi-year (2015-2023) assessment of long-range transport and regional dynamics in the Central Mediterranean basin.
High-altitude stations provide unique insights into background chemistry, although decoupling long-range transport from local mountain dynamics remains challenging. This study presents a comprehensive, high-resolution, multi-year (2015-2023) record of TGM/GEM, GOM, and PBM at the Monte Curcio observatory. The station's...
