About

John DeVore’s research centers on atmospheric optics, cloud physics, and aerosol characterization, with a particular focus on retrieving microphysical properties from solar radiation measurements. His most influential contribution is the development and field deployment of the Sun and Aureole Measurement (SAM) aureolegraph, a novel instrument designed to capture solar aureole patterns produced by thin clouds. In his 2009 paper on this work—cited 23 times—DeVore demonstrated how aureole measurements could be used to retrieve cloud properties such as particle size and optical thickness, providing a valuable tool for climate and atmospheric radiation studies. This work was conducted at the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Program Central Facility, underscoring its relevance to large-scale climate research. DeVore also contributed a theoretical advance in his 2011 paper on the truncated geometric approximation, which offers a simple yet powerful method for estimating the size distribution of small atmospheric particles from spectral optical depth data. While less cited, this work provides a practical analytical shortcut for aerosol studies. Together, DeVore’s contributions bridge instrumental innovation and theoretical modeling, offering researchers accessible tools for probing the optical properties of clouds and aerosols.
