Types of Measuring Stations
• E (incl. T and partly G): Energy balance station (friction velocity, sensible and latent heat flux, ground heat flux, four components of net radiation)
5th COPS Workshop, Hohenheim, 26-28 March 2007
Types of Measuring Stations
• T: Turbulence station (friction velocity, sensible heat flux)
5th COPS Workshop, Hohenheim, 26-28 March 2007
Types of Measuring Stations
• G: Ground measurements (ground heat flux, soil temperature and moisture), also listed in soil moisture network
Soil heat flux: 0.1 mSoil temperature: 0.05 and 0.2 m (0.02, 0.1, 0.5 m)Soil moisture: 0.05 and 0.2 m (0.02, 0.1, 0.5 m)

Types of Measuring Stations
• S: Sodar (and RASS) measurements

Unification of Turbulence Measurements
• Calculation with the turbulence software package TK2 (University of Bayreuth)
• Data quality code for all flux measurements• Data selection according to internal
boundary layers and footprint• Uniform ground heat flux calculation
(concept: University of Bayreuth)
• Further analysis (next funding period)
5th COPS Workshop, Hohenheim, 26-28 March 2007
Quality Assurance and control
• Internal boundary layers

Connection with other network
• Soil moisture network: Unification of soil measurements.
• Mesonet: Universities of Vienna, Munich, Freiburg and others
• Data transfer: non real-time (after the experiment)
• Data basis: NetCDF up to now not prepared
