Biography

Derek Day received BS and MS degrees in 1990 and 1992 respectively from Northern Arizona University. Both degrees were related to chemistry and environmental science. My areas of interest include the formation, transport, and impacts of ambient aerosols. I’ve worked at CIRA since 1992 and been involved in several large field campaigns at national parks investigating the physical, chemical, and optical properties of ambient aerosols. My particular area of expertise is aerosol light scattering as a function of relative humidity.
