Dr. Avallone’s
expertise centers on the development of instrumentation for measuring trace
atmospheric species at high data rate and with high sensitivity and
specificity. Instrumentation designed and built by her group has been employed
in numerous field projects to study the formation and radiative impact of cirrus
clouds, the formation and dispersion of rocket exhaust plumes, and polar
boundary-layer ozone fluxes and ozone budget. Dr. Avallone’s instrumentation
has been used on the ground, on balloons and on numerous aircraft, including
NASA’s ER-2, DC-8, and WB-57F; NSF/NCAR’s C-130 and Gulfstream G-V; and the UND
Cessna Citation. Dr. Avallone has extensive experience working in the high latitudes,
both on aircraft and on the ground. She has participated in field experiments
in Svalbard;
