The ETC coordinates and supports the ICOS Ecosystem network through coor- dination and training activities. It provides technical assistance to ICOS Ecosystem sites and develops and tests new measurement methods and instruments. It also calculates, processes and performs quality con- trol on ICOS Ecosystem data. The ETC develops new methods for data processing and manages the ETC database, web pages and tools.
ETC consists of four main units
Unit 1) The Executive Committee Unit’s main tasks include communication and interaction with the ICOS community and other Central Facilities. The unit also organises annual assessments of ETC operations and plans its medium- and long-term ac- tivities.
Unit 2) The Data Unit’s main tasks include NRT data and metadata collection as well as automatic data quality assistance, quality control and process- ing. The unit shares, distributes and archives data
and develops tools for data exploration and valida- tion. This unit also maintains an alert service in case of data problems and inconsistencies.
Unit 3) The Test Unit’s main tasks include the evaluation of new sensors and prototypes and the development of new methods. The unit is responsi- ble for interactions with instrument manufacturers and research centres as well as for roving system management for site validation and parallel meas- urements.
Unit 4) The Network Unit’s main tasks include providing assistance to the ICOS Ecosystem stations and evaluation of station performances. The unit or- ganises training sessions for site managers and tech- nicians and forms workgroups for protocol devel- opment. This unit also analyses soil and vegetation samples and takes care of their storage.
