abstract = {During recent years several research institutes in
northern Fennoscandia have deployed imaging instruments of
a new generation, electron multiplying charge coupled
devices (EMCCDs), for imaging the northern lights (Aurora
Borealis). 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.},

volume emissions are investigated. Data from the Auroral
Large Imaging System (ALIS) cameras at field stations in
northern Sweden and Norway are used to calculate
tomography-like estimates of the N2+(1N) emission at
4278~{\AA} and the O(1S) emission att 5577~{\AA}.
Applications of the spectroscopic ratios include 1)
estimates of electron energy spectra, which have
applications in auroral theory and in estimating ionisation
rates for incoherent scatter radar and ion chemistry model
studies and 2) direct estimates of the chemical composition
of the lower thermosphere, as the 5577 emission is excited
at least partly through chemistry.},

dual-polarization measurements with the two remote
receiving stations. 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. An overview plot of the results is shown in Fig 1. },
