Mesospheric Ozone has significant chemical impact in the upper atmosphere, and its seasonal and annual variability needs to be better understood. Many large and expensive satellites have been flown over the last 20 years in search of such measurements.
By carefully investigating the role of ozone in the high-temperature, hypersonic environment of overdense meteors, we have been able to...

The ERWIN-II (improved E-Region Wind Interferometer) is a Michelson interferometer, located at the Polar Environment Atmospheric Research Laboratory (PEARL) in Eureka, Nu. It measures the airglow irradiance and winds via Doppler shifts in the airglow emissions – green line (557.7 nm) at a height of ~97 km, O2 (560 nm) at ~94 km, and OH (543 nm) at ~87 km. These measurements are made at a very...

The Michelson Interferometer for Airglow Dynamics Imaging (MIADI) is a ground based optical instrument designed to obtain two dimensional images of the line of sight Doppler wind and irradiance field in the mesosphere. The intention of the instrument is to measure the perturbations in the airglow due to the presence of gravity waves. In its current configuration, the instrument observes a ~80...

Fourier transform infrared (FTIR) spectroscopy provides a powerful tool for probing the atmosphere. Solar absorption spectroscopy can be used to measure atmospheric abundances of tropospheric and stratospheric trace gases, while emission spectroscopy also provides information about clouds and the radiation budget. High-quality time series of composition measurements, along with critical...
