Levoglucosan indicates high levels of biomass burning aerosols over oceans from the Arctic to Antarctic
Biomass burning is known to affect air quality, global carbon cycle, and climate. However, the extent to which biomass burning gases/aerosols are present on a global scale, especially in the marine atmosphere, is poorly understood. Here we report the molecular tracer levoglucosan concentrations in m...
