Abstract: To distinguish between Fe(II) and Fe(III) species in atmospheric water samples, we have adapted an analytical procedure based on the formation of a specific complex between Fe(II) and ferrozine (FZ) on a chromatographic column. After elution of Fe(III), the Fe(II) complex is recovered with water-methanol (4:1). The possibility of trace iron measurements in this complex medium by graphite-furnace atomic-absorption spectrometry has been investigated. A simplex optimization routine was required to complete the development of the analytical method.

. (2008). Polarization in aurorae: A new dimension for space environments studies, ., 35, L08804. GEOGRAPHICAL RESEARCH, 35(L08804).
Abstract: The polarization of emission lines is a noteworthy
observational parameter in astronomy. However, it has
never been detected without ambiguity in planetary upper
atmospheres. Theoretical considerations have suggested that
the polarization of the thermospheric oxygen red line
(630 nm) could exist in the polar cap region. We present
here its first successful measurement at Svalbard in January
2007, during active geophysical conditions. We assign its
origin and variability to complementary effects between
permanent low-energy electron precipitation and sporadic
auroral events. Implications in physics, geophysics and
planetary science are foreseen. In physics, it raises the
question of the polarization of a forbidden transition by
electron impact which is still unknown. In geophysics, it
provides a new parameter to constrain the thermospheric
models. In planetary science, it makes it possible to derive
the local configuration of the magnetic fields. It therefore
opens new perspectives for future space missions towards
other planets.

Belehaki, I. Stanislawska, J. Lilensten. (2009). An Overview of Ionosphere – Thermosphere Models Available for Space Weather Purposes.
Abstract: Our objective is to review recent advances in ionospheric and thermospheric modeling that
aim at supporting space weather services. The emphasis is placed on achievements of European
research groups involved in the COST Action 724. Ionospheric and thermospheric modeling on time
scales ranging from a few minutes to several days is fundamental for predicting space weather effects
on the Earth's ionosphere and thermosphere. Space weather affects telecommunications, navigation
and positioning systems, radars, and technology in space. We start with an overview of the physical
effects of space weather on the upper atmosphere and on systems operating at this regime. Recent
research on drivers and development of proxies applied to support space weather modeling efforts are
presented, with emphasis on solar radiation indices, solar wind drivers and ionospheric indices. The
models are discussed in groups corresponding to the physical effects they are dealing with, i.e.
bottomside ionospheric effects, trans-ionospheric effects, neutral density and scale height variations,
and spectacular space weather effects such as auroral emissions. Another group of models dealing with
global circulation are presented here to demonstrate 3D modeling of the space environment. Where
possible we present results concerning comparison of the models' performance belonging to the same
group. Finally we give an overview of European systems providing products for the specification and
forecasting of space weather effects on the upper atmosphere, which have implemented operational
versions of several ionospheric and thermospheric models.
