Meteor emission spectra provide an
insight into the chemical nature of meteoroids ablating
in the atmosphere, but also useful information about
the mechanisms that control this ablation process [1, 2,
3, 4]. For this reason, an array of spectrographs has
been deployed at several meteor observing stations
operated by the University of Huelva, in Spain. These
stations work in the framework of the SPanish Meteor
Network (SPMN). The first of these devices, which
were based on low-lux CCD video cameras endowed
with holographic diffraction gratings, started operation
in 2006 at the station in Sevilla and also at the Cerro
Negro mobile station [5]. Later on, slow-scan CCD
spectrographs were also employed at both locations.
Nowadays, these spectral cameras operate in a fully
autonomous way at 7 meteor stations in the framework
of the SMART project, which is the acronym for Spectroscopy
of Meteoroids in the Atmosphere by means of
Robotic Technologies. Favorable weather conditions
in Spain play a key role in the successful development
of this systematic spectroscopic campaign. A description
of the main developments performed during 2013
is given here.
