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.20212021-10-25 09:04:50Neznano6871COBISS_ID: 82140931UDK: 504ISSN pri članku: 1867-1381DOI: 10.5194/amt-14-6821-2021NUK URN: URN:SI:UNG:REP:QDMVEFLHsl
