…and trends
H2CO annual trend [1014 molec.cm-2 yr-1]: 1997-2010
» Large positive trends in Chinese and Indian megacities.
» Negative trends over Tokyo, London, Paris.
» Negative trends over Eastern United States cities.
» but positive trends over Los Angeles and Phoenix.

Upcoming Stratosphere
Satellite mission proposed by BIRA-IASB, supported by
BelSPo and funded by PRODEX.
Industrial partners : OIP (P/L) and QinetiQ Space (P/F)
Mission goals:
 Measurements of atmospheric
trace gases concentration
profiles with global coverage in
3 days and ~500 m spatial
sampling from UT/LS to US.
 Target species : O3, NO2, CH4,
H2O, BrO, PSC, aerosols, ..
Current status : Phase B

Climate Change
BIRA-IASB is involved in 3 out of the 4 ESA Climate Change
Initiative projects dealing with atmospheric Essential Climate
Variables: O3, aerosol, greenhouse gases.
Objective:
to exploit the long-term Earth Observation Data from (ESA)
satellites to generate climate-relevant data records
e.g.,
homogenised
total O3 column
record

Multiscale Model
PICASSO
Pico-Satellite for Atmospheric and Space Science Observations
BIRA-IASB and KSB-ORB
A strategic project
 to demonstrate / verify use of cubesat technology for in-situ
and remote sensing studies of atmospheres
 To acquire experience with cubesat technology and miniature
payloads
PICASSO is a triple CubeSat
embarking 3 scientific instruments:
 VISION, a visible and nearinfrared hyper-spectral imager
(BIRA-IASB)
 mNLP, a multi-Needle Langmuir
Probe (BIRA-IASB)
 μBOS, a micro-Bolometer
Oscillation System (KSB-ORB)

Solar spectral irradiance
SOLarSPECtrum onboard
the ISS
Mission goals:
 refurbish the
instrument and to adapt
it for a long term
mission (2008-2016),
 to extend the
wavelength coverage
(166 – 3088 nm)
 to reduce the
uncertainties on the
measurements.

Conclusion
M. De Mazière
Spaceweek 2012
The research at the Belgian Institute for Space Aeronomy
has very much evolved since the time of ATLAS-1, hand in
hand with the evolution of (space) technology and the needs
in Earth Observation
There is a strong focus on space-based research but….
Involvement in
 ground- and airborne observations
 for validation of satellite measurements
 for long-term high-quality monitoring
 laboratory and field experiments
 for gathering spectroscopic data
 process studies and better knowledge of chemical
reactions in the atmosphere
 for emission measurements
 ….
 modelling and theoretical studies
Indispensable
