Towards a more resilient aviation system in Europe

14 December 2016 - Aviation is one of the most critical infrastructures of our times. Even comparably short interruptions in commercial aircraft operations can cause economic damages in the billion-dollar range. Natural or manmade airborne hazards such as volcanic ash clouds and nuclear releases may crucially effect the operations of the worldwide aviation system. The Eyjafjallajökull eruptions in Iceland 2010 showed the vulnerability of such a complex system, with thousands of passengers stranded and stakeholders as well as decision makers unprepared to cope with such an event.

Safe flight operations, air traffic management and air traffic control are a shared responsibility of EUROCONTROL, national authorities, airlines and pilots. Despite experiences as in 2010 there is still a gap between available data and information and the stakeholders’ needs for high quality data in order to make consistent decisions.

With the EUNADICS-AV (“European Natural Disaster Coordination and Information System for Aviation”) Project, the Consortium envisions to close this gap.

NOMADs first view of the Martian atmosphere

29 November 2016 – “I am thrilled to see the hard work of the NOMAD team successfully culminating in the first scientific data of the Martian atmosphere! This is the result of a tight international collaboration, lead and mainly financed by Belgium,” says Ann Carine Vandaele, principal investigator of the NOMAD instrument onboard ExoMars 2016 and scientist at the Royal Belgian Institute for Space Aeronomy.

NOMAD Calibration Orbit

“Our instrument has a detection sensitivity that is improved by several orders of magnitude compared to previous missions. Hence, it is expected that both the main constituents and the trace gases (like methane) in the Martian atmosphere will be much better understood.”

Exceptional SO2 detection due to sulphur mine burning in Iraq

On 24 October 2016, 07:08 UTC, the GOME-2 /MetOp-A instrument implemented in the SACS system detected a very unusual plume of SO2 over Iraq, Syria and Turkey, and automatically notified the subscribed users, about 2 hours after the measurement was performed. This notification was confirmed few hours later by the OMI instrument which observed enhanced local SO2 emission in the area (see left Figure 1).

Map SO2 detection

This exceptional detection of SO2 is due to the burning of the sulphur mine of Al-Mishraq by fighting forces. This voluntary act led to the massive release of sulphur species in the atmosphere which could be detected from space.

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.

Formaldehyde

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.
