Gravity wave instability structures and turbulence from more than 1.5 years of OH[ast] airglow imager observations in Slovenia
Samo Stanič, Sabine Wüst, Michael Bittner, Carsten Schmidt, René Sedlak, Patrick Hannawald, 2021, original scientific article

Abstract: We analyzed 286 nights of data from the OH* airglow imager FAIM 3 (Fast Airglow IMager) acquired at Otlica Observatory, Slovenia, between 26 October 2017 and 6 June 2019. Measurements were performed with a spatial resolution of 24 m per pixel and a temporal resolution of 2.8 s. Multiple turbulence episodes were observed and the energy dissipation rate in the upper mesosphere/lower thermosphere region was estimated from image sequences in 25 cases. Values range around 0.08 and 9.03 W/kg and would lead to an approximated localized maximum heating of 0.03–3.02 K per turbulence event.
