Research Topics and Related Activities
- Study of the chemical composition of the Earth's atmosphere
- Instrumental developments
- Electronics applied to the Fourier transform technique and to the information processing
- Solar infrared spectroscopy (1-50 µm)
- Related activities :
- Data archiving
- Validation and intercomparaison activities
Instrumentation
Exploitation of Fourier transform interferometers in order to record infrared solar spectra :

|
|
at the Laboratoire de Physique Atmosphérique et Solaire, located in the building of the International Scientific Station of the Jungfraujoch, Switzerland |
- with instruments in orbit (ACE-FTS, ATMOS)
- on board the stratospheric balloon-borne
Research Context
The Jungfraujoch Observatory was chosen as one of the main sites of the Primary
Alpine Station, which is member of the NDACC
(Network for the Detection of Atmospheric Composition Change, formerly NDSC)
network, since its foundation in 1991. Within this context, GIRPAS participates
in the monitoring of the terrestrial atmosphere state at the mid-latitudes of
the northern hemisphere.
The different activities of the group were also integrated in important programmes like :
o the national belgian programme "Global Change" in the framework of the IGBP (International Geosphere Biosphere Programme) and of the UNEP (United Nations Environmental Programme)
o
the ATLAS (ATmospheric
Laboratory for Applications and Sciences) programme -
Since the beginning of the 90's, GIRPAS participated in numerous european programmes and campaigns, among which :
o EASOE (European Arctic Stratospheric Ozone Experiment)
o
SESAME
(Second European Stratospheric
o EUROTRAC - TOR (Tropospheric Ozone Research)
o THESEO, THESEO2000 (THird European Stratospheric Experiment on Ozone)
Within belgian "Global Change" programmes, coordinated by the Belgian Science Policy, we largely contributed to the following projects :
o ESAC-I (Experimental Studies of Atmospheric Changes - GC-DD context)
o ATMOS (Atmospheric Trace MOlecule Spectroscopy)
Recent and ongoing activities
Participation in european programmes and campaigns:
o
EUROTRAC-2 (The European Experiment on
the Transport of Environmentally Relevant Trace Constituents over
o EUMETSAT (EUropean organisation for the exploitation of METeorological SATellite)
o ENVISAT (ENVironment SATellite)
o TROPOSAT (The Use and Usability of Satellite Data for Tropospheric Research )
o ENVINET (European Network for Arctic-Alpine Environmental Research)
Scientific projects:
·
Within belgian
"Global Change" and Science for a Sustainable Development programmes, coordinated by the Belgian Science Policy:
o ESAC-II ("Global Change, Ecosystems and Biodiversity")
o
AGACC (Advanced exploitation of
Ground-based measurements for Atmospheric Chemistry and Climate Applications)
·
Within belgian "PRODEX" (PROgramme de
Développement d'EXpériences scientifiques, ESA) context :
o ACE – Cly-Fy (Atmospheric Chemistry Experiment, and global monitoring of the stratospheric Cl and F loadings)
o IASI (Infrared Atmospheric Sounding Interferometer)
o CINAMON-OMI (contribution to the calibration/validation of ENVISAT and OMI instruments)
o
SECPEA
(Space-based Exploration of the Chemistry and Physics of the Earth's Atmosphere)
·
Within European Community -
environmental framework programmes :
o
SOGE
(System for Observation of halogenated Greenhouse gases in
o UFTIR (Time series of Upper Free Troposphere observations from a european ground-based FTIR network)
o EVERGREEN (EnVisat for Environmental Regulation of GREENhouse gases)
o GMES-GATO (Global Monitoring for Environment and Security-Global ATmospheric Observations)
o HYMN (Hydrogen, Methane and Nitrous oxide: Trend variability, budgets, and interactions with the biosphere)
o GEOMON (Global Earth Observation and Monitoring of the atmosphere)
