Chemical characterisation of marine aerosol in the Azores
Copyright © 2001 Published by Elsevier Ltd. Ground-level concentrations of particulate matter with less than 10μm in diameter were measured in Azores Archipelago, mid-North Atlantic Ocean. Three intensive research campaigns took place between April and August 99. Observed average concentrations were...
