(10.) 11. - 13. May 2015: NORA Workshop in Göteborg, Sweden

"Gas flux measurements in terrestrial ecosystems - state of the art and emerging technologies", University of Gothenburg. 

Soils are important sources and sinks of trace gases in the atmosphere. Understanding and manipulation of contributing processes and their controls as well as determination of anthropogenic effects rely on precise quantification of these trace gas fluxes. Emerging technologies and novel approaches are developing fast today and open new possibilities and applications. This meeting brought together frontrunners in this field to present current and future developments.

From the 10th till 13th May 2015 a workshop on N2O and trace gas emissions (a NORA outreach) was held at the University of Gothenburg (UGOT). The workshop was hosted by Leif Klemedtsson and jointly organized by UGOT (Leif Klemedtsson), Yara (Carlo Lammirato, ER2), and NMBU (Lars Bakken and Jan Reent Köster, ER1). The networks of ICOS Sweden and the Swedish Infrastructure for Ecosystem Research (SITES) supported the workshop.

The workshop started on Sunday evening (10th May) with a cozy ice-breaker party at the Department of Earth Sciences, UGOT, which was joined by about 30 workshop participants, allowing the attendees to get each other to know and to have first discussions in a relaxed atmosphere. In total 62 attendees from 13 European countries as well as from the US participated in the workshop and contributed with 40 presentations, of which 27 were oral presentations, and made the workshop the success we think it was. Five companies providing equipment for trace gas and atmospheric measurements were represented at the workshop, and three of them – Thermo Scientific, Picarro Inc., and MS Nordic – supported the workshop by sponsoring, which is greatly acknowledged.

The Scientific programme started on Monday (11th May) morning in UGOTs Conference Centre Wallenberg with a welcome by Leif and introductions on ICOS Sweden and NORA by Anders Lindroth (Uni Lund) and Åsa Frostegard (NMBU), followed by sessions on N2O relevant biological processes, modelling of N2O fluxes, and micrometeorological flux measuring techniques. A poster session was held after the lunch break. This first day was closed during a great conference dinner.

On Tuesday all workshop participants went on a field trip, visiting three different field sites, including a willow plantation, an agricultural experimental farm site, and a forest site enclosing a swamp. Here, several Eddy Covariance systems for measuring N2O, CO2, and CH4 fluxes were presented, but also a gradient tower, VOC measurements, and the NMBU field robot in operation measuring N2O emissions in a wheat field. Despite a little rain staring around lunch time, the atmosphere was great with many interesting discussions.

On Wednesday, 13th May, there were sessions about stable isotope techniques, laser and fast box approaches, and on automated and robotic field platforms for measuring trace gas fluxes. On this day, the scientific programme ended around 2 pm and the workshop was closed by Leif.

The feedback we received from workshop participants so far is without exception very positive, which confirms our impression of a very interesting and successful event.
