Description and characterization of an on-line system for long-term measurements of isoprene, methyl vinyl ketone, and methacrolein in ambient air.
27
TL;DR: A detailed technical description of the system that was set up for long-term on-line measurements of isoprene and two of its major degradation products, methyl vinyl ketone and methacrolein is presented in order to provide a better understanding of the role of forest stands as a complex source of reactive trace gases into the troposphere and to elucidate the roles of forests as chemical reactors.

A new mechanism for regional atmospheric chemistry modeling
TL;DR: The Regional Atmospheric Chemistry Mechanism (RACM) as discussed by the authors is a gas-phase chemical mechanism for the modeling of regional atmospheric chemistry, the mechanism is intended to be valid for remote to polluted conditions and from the Earth's surface through the upper troposphere.
