In this study applications of remote sensing of auroral 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.},

  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.},

		  structure of the night sector diffuse auroral zone,
		  observed simultaneously with optical instruments (ALIS)
		  from the ground and the FAST electron spectrometer from
		  space 16 February 1997. Both the optical and particle data
		  show that the diffuse auroral zone consisted of two
		  regions. The equatorward part of the diffuse aurora was
		  occupied by a pattern of regular, parallel auroral stripes.
		  The auroral stripes were significantly brighter than the
		  background luminosity, had widths of approximately 5 km and
		  moved southward with a velocity of about 100 m/s. The
		  second region, located between the region with auroral
		  stripes and the discrete auroral arcs to the north, was
		  filled with weak and almost homogeneous luminosity, against
		  which short-lived auroral rays and small patches appeared
		  chaotically. From analysis of the electron differential
		  fluxes corresponding to the different regions of the
		  diffuse aurora and based on existing theories of the
		  scattering process we conclude the following: Strong pitch
		  angle diffusion by electron cyclotron harmonic waves (ECH)
		  of plasma sheet electrons in the energy range from a few
		  hundred eV to 3 4 keV was responsible for the electron
		  precipitation, that produced the background luminosity
		  within the whole diffuse zone. The fine structure,
		  represented by the auroral stripes, was created by
		  precipitation of electrons above 3 4 keV as a result of
		  pitch angle diffusion into the loss cone by whistler mode
		  waves. A so called },

We present the results of radar measurements during the 4.5-day
campaign around the Leonid maximum in November 15-20 2009, in which we
conducted simultaneous tristatic EISCAT UHF measurements along with
optical EMCCD observations. During the last 24 hours, we also
performed 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.
