Lay Summary (German)

Lead
Wichtige Probleme von SPARC (Stratosphere-troposphere Processes and their Role in Climate) werden untersucht: Langzeitmessungen von stratosphärischen Ozonprofilen werden statistisch analysiert um zu bestimmen, ob sich die aufgrund der erfolgreichen Umsetzung des Montreal Protokolls (1987) erwartete Umkehr der Trends zeigt. Die atmosphärischen Lebenszeiten von halogenhaltigen Gasen (ozonzerstörende Substanzen) werden mit numerischen Modellen erforscht.
Lay summary

Der Spurenstoff Ozon spielt eine zentrale Rolle in der Atmosphäre: Der Ozonschild in der oberen Atmosphäre filtert die gefährlichen Anteile der Sonnenstrahlung, Ozon ist ein wichtiges Treibhausgas und in erhöhter Konzentration ein Schadstoff für Menschen und Pflanzen. Die Veränderung des Ozonschildes  wird in SPARC  („Ozone Profile Trends“) untersucht, wobei  die  letzten Jahrzehnte wegen der veränderten anthropogenen Emissionen von ozonzerstörenden Substanzen  von grossem Interesse ist.  Die  Langzeitmessungen von verschiedenen Satelliten-instrumenten werden mit statistische Analysen untersucht und mit Bodenmessungen verglichen. Die Ergebnisse dieser Arbeiten sollen in wissenschaftlichen Zeitschriften veröffentlicht werden.

Die ozonzerstörenden Substanzen (z.B. Fluorchlorkohlenwasserstoffe) haben nicht nur zum Abbau der Ozonschicht geführt sondern auch wesentlich zur Klimaänderung beigetragen. Das Montreal-Protokoll (1986) hat diese Emissionen rasch und nachhaltig vermindert, was sich auch auf die Klimaänderung auswirkt. Die atmosphärischen Verweilzeiten dieser Stoffe bestimmen in grossem Ausmass wie viel Ozon in der oberen Atmosphäre zerstört wird und wie lange diese Stoffe zur Klimaerwärmung beitragen. Die Verweilzeiten sind entscheidend für die Zeit, wann und wie der Ozonschild regenerieren wird. Die Unterstützung durch den SNF ermöglichte die wissenschaftliche Mitarbeit in der SPARC ( „Lifetime of Halogen Source Gases“). Die mit einem Chemie-Klimamodell  erarbeiteten Ergebnisse sollen als eigenständigen Beitrag  veröffentlicht werden.

Die durch den SNF finanzierte Mitarbeiterin war als wissenschaftliche Editorin die Hauptverantwortliche für drei Ausgaben der weit verbreiteten SPARC-Newsletters.

Abstract

SPARC (Stratospheric Processes and Their Role in Climate) is one of the four core projects of the WCRP (World Climate Research Programme). WCRP aims to improve the predictability of climate, particularly under the influence of the effects of anthropogenic climate change by facilitating international research collaboration to provide society-relevant science. SPARC was initiated more than 20 years ago and ever since it has stimulated strong scientific collaboration that has lead to excellent, bottom-up driven international research providing deliverables with significant added scientific value. SPARC research is strongly focused on the stratosphere and outcomes of many of the SPARC activities have served as the basis for the regular WMO/UNEP [1] Assessments of Ozone Depletion, as well as the IPCC [2] Assessments of Climate Change. Examples of recent SPARC achievements include the coordination of chemistry-climate modelling and the development of metrics for the evaluation and intercomparison of models, as well as several activities focused on the critical assessment of key long-term observations. A recent review of the WCRP by its governing bodies led to a structural revision, which aims at making the core projects work closer with the new climate services. Through this revision, SPARC’s mandate has been extended to include tropospheric processes influenced by the stratosphere, implying that in future SPARC will include more tropospheric focus in its research activities. SPARC is the only WCRP core project with a strong emphasis on chemistry, and therefore an important SPARC activity is the coordination of work using chemistry-climate models that also include the troposphere. This activity is currently underway as a common effort with IGAC [3] of the IGBP [4]. The SPARC International Project Office (IPO) is essential to the programmatic and operational functioning of SPARC’s scientific activities. It promotes SPARC’s work by (i) publishing SPARC Newsletters that appear twice a year, (ii) producing all SPARC assessment reports, (iii) managing the SPARC website and coordinating outreach and communication activities, and (iv) by organising or assisting with the arrangement of many important international workshops and meetings. It achieves these tasks by keeping itself up-to-date with SPARC science. The SPARC Office is presently located at ETH Zürich in Switzerland, supported by ETH Zürich, MeteoSwiss, FOEN (Federal Office for the Environment) and the WCRP. This funding covers only the essential, “house keeping” activities and is insufficient to continue the provision of “added-value” science that the SPARC Office is expected to provide. To this end, the SNF has supported the SPARC Office through an infrastructure project since February 2012 with a full postdoctoral position for a “Project Scientist”. Already during her first year, the Project Scientist (Dr. Fiona Tummon) was able to make substantial contributions to several of SPARC’s scientific activities, which will result in a number of peer-reviewed first- and co-author publications. With this present application we ask for a continuation of the SNF postdoctoral position for two years. This postdoc will continue with her own SPARC-related research, advance SPARC research activities, take the lead in the production and editing of the SPARC newsletters, scientific reports and review papers, and contribute to the organisation of SPARC’s scientific meetings.
