“International Day for the Preservation of the Ozone Layer”
16 september 2016 - In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Laye.
Global stratospheric ozone amounts stopped decreasing in the late-1990s, and have stabilized at levels about 2-3 % less than those observed in 1980. The latest international assessment of stratospheric ozone (WMO, 2014) has reported a small but statistically significant increase of ozone around 40 km, which has been attributed to both a decrease of ODSs and the cooling of the stratosphere by increased abundance of greenhouse gases.
More recently, several studies have shown signs that total ozone may be starting to recover over Antarctica. Due to the long lifetimes of ODSs in the atmosphere, full stratospheric ozone recovery will take several decades. Stratospheric ozone recovery will also be impacted by climate change.
Substantial Underestimation of Post-Harvest Burning Emissions in the North China Plain Revealed by Multi-Species Space Observations
September 15, 2016 - The large-scale burning of crop residues in the North China Plain (NCP), one of the most densely populated world regions, was recently recognized to cause severe air pollution and harmful health effects. A reliable quantification of the magnitude of these fires is needed to assess regional air quality. The Royal Belgian Institute for Space Aeronomy (BIRA-IASB) and its partners ULB, KNMI (Netherlands) and the Peking University (China) used an eight-year record (2005–2012) of formaldehyde measurements from space to constrain the emissions of volatile organic compounds (VOCs) in this region.
Using inverse modelling, the scientists derived that satellite-based post-harvest burning fluxes are, on average, at least a factor of 2 higher than state-of-the-art bottom-up statistical estimates, although with significant interannual variability.
Crop burning is calculated to cause important increases in surface ozone (+7%) and fine aerosol concentrations (+18%) in the North China Plain in June. The impact of crop fires is also found in satellite observations of other species, glyoxal, nitrogen dioxide and methanol, and researchers show that those measurements validate the magnitude of the top-down fluxes. The study indicates that the top-down crop burning fluxes of VOCs in June exceed by almost a factor of 2 the combined emissions from other anthropogenic activities in this region, underscoring the need for targeted actions towards changes in agricultural management practices.

The antenna is part of a worldwide network that gathers data to improve and refine computer models of the plasmasphere.
Discovery of abundant oxygen in a comet by Rosetta
28 October 2015 - The renowned scientific journal Nature will publish a perplexing discovery on Thursday October 29th: the European Space Agency’s Rosetta spacecraft has discovered – for the first time ever – the presence of oxygen gas O2 in the atmosphere of comet 67P/Churyumov-Gerasimenko.
Moreover, oxygen turns out to be a major component, constituting up to 10% of the comet atmosphere.
Argon discovered in the atmosphere of a comet, thanks to a Belgian instrument.
29 September 2015 - An article published only recently in the scientific journal Science disclosed Rosetta’s discovery of traces of argon in the atmosphere of the comet 67P/Churyumov-Gerasimenko.
We owe this discovery to the DFMS mass spectrometer of the ROSINA instrument. This instrument, which is carried on board the Rosetta probe, was finalised in collaboration with the scientists and engineers of the Royal Belgian Institute for Space Aeronomy (BIRA-IASB). The high resolution of this instrument enables it to detect two variants of argon (isotopes 36Ar and 38Ar).

Once on board, he’ll get to work inside ESA’s Columbus laboratory, carrying out a series of European experiments to test new technologies and operational techniques for future space missions. Belgium is giving operational support for two of them.
The Perseids - watching and listening to falling stars
11 August 2015 - The Perseids - watching and listening to falling stars Like every year, Earth will pass mid August through the trajectory of the dust cloud left behind comet Swift-Tuttle very likely giving us a night sky filled with bright falling stars. The moon will be in a cooperative mood and won't shed its light, thus promising a dark night.
Meteors can also be heard on radio, when transmitted radio signals bounce back on them.
At the Royal Observatory of Belgium, between the prestigious domes, amateur-telescopes will be installed on August 12 to enjoy a beautiful star sky.
The radio receiver from the Belgian RAdio Meteor Stations netwerk (BRAMS) located on the domain will catch the radio signals that mark the presence of the meteors.
Subscriptions for Night of shooting stars are complete. But, no worries, find a dark place outside, lay on your back and enjoy. Late night is the best time.

ESA selects THOR and 2 other M4 mission proposals for a study phase - BIRA-IASB is involved
10 June 2015 - In August 2014, a call for the fourth medium-size (M4) mission opportunity was issued in the frame of ESA's Cosmic Vision Programme with launch foreseen in 2025. ESA received 27 proposals in response to this call, amongst which also THOR (Turbulence Heating ObserveR) in which the Space Physics division at BIRA-IASB is involved. After a thorough evaluation of the scientific and programmatic aspects of all candidate missions, THOR was recommended as one of the three mission concepts to proceed to a Phase 0 study, which is the first official phase of a mission. In mid 2017, ESA will finally decide which of the three will go ahead.

Catching A Comet in Science Magazine
23 January 2015 - In August 2014, the European Space Agency’s Rosetta spacecraft arrived at comet 67P/Churyumov-Gerasimenko. Once in orbit, it swooped as low as 10 kilometers to get unprecedented data from the comet (and to drop off its short-lived Philae lander). Today, Science Magazine is publishing a suite of new papers detailing some of the mission’s first findings.
BIRA-IASB scientists are involved with their analyses of data coming from the ROSINA instrument that measured the coma composition of comet 67P.
These measurements show large fluctuations in composition in a heterogeneous coma that has diurnal and possibly seasonal variations in the major outgassing species:
Other new findings suggest a wide range of deuterium-to-hydrogen (D/H) ratios in the water within Jupiter family objects (based on measurements around the Jupiter family comet 67P) and preclude the idea that this reservoir is solely composed of Earth ocean–like water.
