Workshop | First Announcement
The biosphere-atmosphere exchange and global budget of
carbonyl sulfide
Dates: 5-9 September, 2016
Location: Hyytiälä Forestry Field Station, Finland
Funding: Local travel costs (bus Helsinki-Hyytiälä-Helsinki) are funded by ICOS-Finland. Most
participants will meet their own flight and accommodation costs (ca. €110 per night for a single / € 100
for a shared room, including all meals and saunas, and a boreal dinner). Also, if your schedule does not
match with the organized bus transport, you are asked to cover the local transport by yourself. You
should plan your schedule to arrive in Helsinki on Mon 5 Sept in the afternoon and you can book your
departure flights from Helsinki later than early Friday evening, 5 pm onwards.
Goals of the workshop:
1. Consolidate the international community of scientists working on all aspects of carbonyl sulfide
2. Discuss protocols and develop consensus around calibration, standards, and measurement
techniques
3. Evaluate the current state of the art of:
a. The global COS budget: natural and anthropogenic sources and sinks
b. Using COS to estimate GPP
c. Implementation of COS in biosphere-atmosphere exchange models
d. Drivers and controls of COS fluxes
Abstract:
The coupled vegetation uptake of carbonyl sulfide (COS) and CO2, and the potential to use this coupling
to study large-scale photosynthesis, has prompted exciting new research into the biosphere-atmosphere
exchange of COS recently. Aided by new measurement capabilities, information on leaf, soil and
ecosystem COS fluxes is now being collected in order to develop COS-based estimates of gross primary
production (GPP). These recent investigations complement more established research on the role of
COS in atmospheric chemistry and the sulfur cycle, signifying the importance of COS across Earth system
processes and highlighting the value of establishing strong inter-community dialogue. For COS to
provide improved constraints on GPP estimates requires a more complete understanding of COS
consumption and production processes in soils and the kinetics of plant COS-CO2 uptake across
ecosystems. Extending ecosystem scale information to regional, continental and global scale GPP and to
refine tropospheric COS budgets requires addressing uncertainties in COS production from the ocean,
biomass burning and anthropogenic activities. In parallel, it is essential we bring the information from
laboratory and field measurements to models that can be tested against field data and atmospheric and
satellite COS observations. This workshop will bring together researchers working on all aspects of COS
to evaluate the current state of the art in our understanding, measurement, modeling and application of
COS and to facilitate a synergistic progression of this exciting field.

If you do not know Hyytiälä Forestry Field station, in short: we have organized several international
workshops and summer schools here over the years. We always create a relaxing but inspiring spirit in
the meetings. The closest entertainment (pubs etc.) are kilometers away, which guarantees that we are
together all the time, but we have enough beer etc. in the station. The workshop also includes the
excursion to the SMEAR II field station, which is an ICOS Class 1 atmospheric tall tower and ecosystem
flux tower site (see http://www.atm.helsinki.fi/SMEAR/ and https://www.icos-ri.eu/ ).

Preliminary agenda to be announced by mid-April 2016. The final registration is requested by end May.
