Integration of Atmospheric Chemistry Issues:
Progress in atmospheric chemistry issues is made by many scientists, publishing their results in a wide range of journals. David Parrish has a demonstrated capability of publishing papers that integrate past, sometimes divergent results, with important advances. The result is a wide spectrum of landmark papers that coordinate our advancing knowledge of important issues in atmospheric chemistry. Examples include studies that span all areas of atmospheric chemistry, including emissions (Parrish, 2006; Parrish et al., 2009b), air pollution in mega-cities (Parrish and Zhu, 2009; Parrish et al., 2011), urban photochemistry (Parrish et al., 2012), impact of intercontinental transport of pollutants (Parrish et al., 2010; Law and Parrish, 2011) and character of the remote troposphere (Parrish et al., 2013; 2014).
