About Me:

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.

Past Work

Hygroscopicity of aerosol generated from burning two different forest fire fuels

Thursday, March 13, 2014

DerekDayFigureThe figure shows data from smoke aerosols. The left hand plots show relative chemical composition from electron microscopy, while the right hand plots show aerosol particle growth as a function of humidity as measured by nephelometry. Note the top set of plots depict a non-hygroscopic aerosol dominated by carbon, while the lower set of plots show an aerosol which takes up significant water and is composed of significant quantities of inorganic species. In this study we have shown that aerosol water uptake is dominated by the inorganic component of smoke aerosols.
