In the coming years and decades, advanced space-and ground-based observatories will
allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially …

In the past 40 years, atmospheric chemists have come to realize that halogens exert a
powerful influence on the chemical composition of the troposphere and through that …

Atmospheric methane is both a potent greenhouse gas and photochemically active, with
approximately equal anthropogenic and natural sources. The addition of chlorine to the …

Observational evidence shows the ubiquitous presence of ocean-emitted short-lived
halogens in the global atmosphere,–. Natural emissions of these chemical compounds have …

The open burning of waste, whether at individual residences, businesses, or dump sites, is a
large source of air pollutants. These emissions, however, are not included in many current …

The nitrate radical, NO3, is photochemically unstable but is one of the most chemically
important species in the nocturnal atmosphere. It is accompanied by the presence of …

The Indian Ocean Experiment (INDOEX) was an international, multiplatform field campaign
to measure long-range transport of air pollution from South and Southeast Asia toward the …

In March 2006 two instrumented aircraft made the first detailed field measurements of
biomass burning (BB) emissions in the Northern Hemisphere tropics as part of the MILAGRO …

CH4 is the most abundant reactive greenhouse gas and a complete understanding of its
atmospheric fate is needed to formulate mitigation policies. Current chemistry-climate …

During the fourth Fire Lab at Missoula Experiment (FLAME-4, October–November 2012) a
