EMCCDs eliminate readout noise by on-chip electron multiplication before the readout amplifier, and therefore the much higher quantum efficiency of the bare CCD as compared with image-intensified cameras can be utilized[1]. Therefore EMCCDs allow high-speed imaging or imaging of very weak emissions, improving the understanding of plasma-physical processes in the Earth's environment and auroral energy deposition into the atmosphere. Other applications include meteor and airglow research. Challenges in the use of these instruments include 1. Geometrical calibration (i.e. modelling the projection from geographical to pixel coordinates). A study of different projection models based on star mapping is presented. 2. Intensity calibration, including flat-field and absolute radiometric calibration. The use of star spectra for this purpose is discussed.}, alis = {enell2011op}, irf = {enell2011op}, braendstroem = {enell2011op} }

Due to significantly improved sensitivity of the detection algorithms, we obtained a larger meteor detection rate than in previous studies at EISCAT UHF, peaking at 200 detections per hour at 6 UT. No significant increase in meteor detection rate was observed during the peak of the Leonid shower. We detected several low altitude trail-like structures, the lowest one at 60 km.
