Global Atmospheric Composition Effects from Marine Isoprene Emissions.

Isoprene emissions, primarily of biogenic origin, play an important role in atmospheric chemistry and climate. However, the atmospheric implications of marine isoprene emissions remain underexplored due to sparse in situ measurements and the intricate mechanisms governing isoprene in the upper ocean. This study uses 20 years of MODIS satellite observations to upscale isoprene production and loss rates derived from laboratory experiments, enabling global modeling of aqueous isoprene concentrations and emissions.
