longtime member of the Center for Atmospheric and Space Sciences and Professor
of Physics at Utah State University, died on September 27, 2022 at his home in
Logan, Utah. Dr. Wickwar was an early pioneer in Aeronomy and Space Physics,
which is a field devoted to the scientific study of the physics and chemistry
of the upper atmosphere of the Earth and other planets. Dr. Wickwar moved to
Logan in 1988 to join the faculty of USU to take advantage of the low level of
light pollution in Northern Utah's Cache Valley. Here he would create a unique,
laser- based upper atmospheric observatory to study the complex conditions of
the Earth's atmosphere located at the edge of geospace above 100 km. </span></p>

contributions early in his career to the field of aeronomy was to realize and
encourage through both his leadership and example the merits of collaborative
investigations that could be accomplished through the combination of both radar
and optical measurements to achieve a broader perspective on the atmospheric
phenomena being studied. At USU, Dr. Wickwar taught graduate courses in optics
and aeronomy while serving over many years as a thesis advisor for multiple
graduate students. He has been the principal investigator on numerous grants
involving studies of the upper atmosphere employing lidar (light detecting and
ranging) systems, photometers, Fabry-Perot interferometry, and
incoherent-scatter (IS) radar. From 1973 to 1988, Dr. Wickwar was employed at
SRI International in Menlo Park, California, where he was co-principal
investigator of the Sondrestrom, Greenland based IS radar and principal
investigator on numerous IS radar studies. </span><span style="color:black"></span></font></p>

aeronomy was created in the wake of the US-USSR nuclear Test Ban Treaty in
1963, with the US wanting to better understand the possible effects of high
altitude nuclear detonations on long-range communications. By using the
recently created IS radar systems, scientists were able for the first time to
observe the ionospheric physics associated with high altitude detonations. The
thinking at the time was that if the US or others were to ever repeat the high
altitude nuclear tests or, more ominously, in the event of a nuclear war, an IS
radar (with the capability of measuring plasma densities, temperatures, and
motions) would be a much better diagnostic of the fundamental processes that
produced the observed effects on communications. Now, modern applications of
these technologies are employed to better understand global climate changes, among
other natural phenomena. </span></font></p><p class="MsoNormal" style="vertical-align:baseline;margin:0in"><font face="arial, sans-serif"><span style="color:rgb(64,79,87);border:1pt none windowtext;padding:0in">

esoteric scientific innovations and discoveries, but he was also thoroughly at
ease with and enjoyed interacting with non-science focused students while
teaching two beloved introduction to sciences courses for USU undergraduate
students. Born in New London, Connecticut, in 1943, Dr. Wickwar's early years
were spent in New York City, where his British-born father William Hardy
Wickwar worked at the United Nations and mother Margaret Wickwar as a social
worker and later a museum docent. Dr. Wickwar's formative years were spent in
Princeton, New Jersey, where as a young man he occasionally encountered Albert
Einstein, who was an early inspiration for Dr. Wickwar's lifetime love of
physics. Dr. Wickwar's father's work as an international civil servant at one
point took Dr. Wickwar to Lebanon, where he learned French at the Jesuit School
of Beirut. Upon returning to the US, he attended Pomfret School in Connecticut,
and later gained admission to Harvard College's Class of 1965 where he majored
in Physics. He received a PhD in Space Physics at Rice University in 1971 under
the mentorship of Dr. William E. Gordon, who was one of the creators of the
Arecibo IS radar in Puerto Rico. Dr. Wickwar also performed postdoctoral
research at Yale University. Dr. Wickwar maintained that from an early age his
parents nurtured his many hobbies, including photography, which became a
lifetime passion. His interest in photography served as his early introduction
to optics, the underlying basis for the complex lidar and other optics-based
systems he employed in his academic and research studies. </span><span style="color:black"></span></font></p>

Wickwar was one of the principal investigators in a large multi-university
collaborative grant from the Defense Advanced Research Program Agency (DARPA)
to employ Dr. Wickwar's lidar system to collect detailed density and
temperature measurements from the mesopause region - the junction between
Earth's upper atmosphere and space. </span></font></p><p class="MsoNormal" style="vertical-align:baseline;margin:0in"><font face="arial, sans-serif"><span style="color:rgb(64,79,87);border:1pt none windowtext;padding:0in">

collegial relations with many aeronomy scientists around the world.
His passion and strong interest in aeronomy and space physics research
will be very much missed by friends and colleagues. </span><span style="color:black"></span></font></p><div><br></div><div><span style="font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:14px">Jan Sojka (</span><span style="color:rgb(0,0,0);font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px">Head of the USU Department of Physics)</span><br></div><div><br></div></div>
