ICOS-CH, Phase 2, is the Swiss contribution to the Integrated Carbon Observation System Research Infrastructure (ICOS RI) which entered into its operational phase end of 2015 (as Integrated Carbon Observation System European Research Infrastructure Consortium, ICOS ERIC). Overarching goals of ICOS RI are to quantify and to understand the greenhouse gas (GHG) balance of the European continent and adjacent regions based on highly standardized measurements (i.e., sensors and protocols) in the atmosphere, in terrestrial ecosystems and in the ocean, and to distribute data and data products to stakeholders and user communities. With the ICOS-CH network, i.e. ETH Zurich (National Focal Point), Empa, WSL, University of Bern, University of Basel and MeteoSwiss, Switzerland participates in ICOS RI since its beginning in 2013. Two Class 1 sites had been chosen due to their science history: one ecosystem site (Davos, DAV) and one atmospheric site (Jungfraujoch, JFJ). During Phase 1 (2013-2017), both sites have been upgraded according to ICOS RI requirements, when specifications and protocols were available, while basic measurements continued. At DAV, a new data acquisition system, near-real time data transfer and data processing were developed, tested and implemented. 20 years of data were reprocessed and made openly available. Five large automated chambers to measure forest floor GHG fluxes were built and installed in the field, one of them tested for operation during winter. Sensors at the tower were renewed, new equipment for net ecosystem CH4 and N2O fluxes was installed and runs - compliant with ICOS - since end of 2015. At JFJ, ICOS conforming continuous GHG analysers were installed and underwent the required testing. The ICOS mobile lab was installed at JFJ for six weeks to audit setup and instrument performance. Automated data processing was implemented to allow direct data transfer to the central database. A ceilometer to determine the planetary boundary layer (PBL) height above JFJ was installed at the Kleine Scheidegg, approximately 5 km north and 1.5 km below JFJ, and extensive algorithms for PBL detection were developed and validated. Flask sampling continued. Both sites were among the first within ICOS RI to enter the labelling process in 2016 (Step 1 successfully finished, Step 2 on-going). Swiss staff participated in training courses on ICOS quality assurance procedures.In Phase 2 (2017-2020), the Swiss contribution to ICOS RI will be coordinated within Subproject A, also responsible for communication within and beyond ICOS-CH. The site infrastructure needs to be completed according to the finalized ICOS RI protocols (in Subprojects B and C for DAV and JFJ, respectively). Then, both sites need to be maintained at Class 1 level, i.e., with comprehensive variable sets, regular measurement campaigns, very high data quality requirements, fast response/repair times when sensors should fail, and near real-time data provision to ICOS RI. This requires continuous data quality assurance and quality control, ensured by well-trained technical staff and data scientists. Thus, ICOS-CH provides a unique opportunity for scientists to contribute to excellent research and scientific innovations based on high precision, continuous, open-access data, a comprehensive set of measurements, an excellent infrastructure as well as on-site validations for research related to Earth system science.
