Helgoland HEL

54°10‘ N / 7°53‘ E

Altitude: 43 m a.s.l.

Tower height: 113 m

The station on the island of Heligoland is a marine station in the German ICOS Atmosphere network and measurements are to begin there in the summer of 2020.

Samples of trace gases are taken at two heights (60 m, 106 m) with a measurement duration of 5 minutes per height, sequentially sampling both heights. A Picarro G2301 CRDS analyser is used to record CO2 and CH4. For the analysis of N2O and CO, the station is equipped with a Los Gatos LGR 30-EP instrument.

The meteorological parameters are observed using the following instrumentation:

• Air temperature and humidity: Vaisala HMP155
• Wind direction and speed: Thies Ultrasonic Anemometer 2D UA2D
• Air pressure: Vaisala PTB330 

These data are supplied on a continuous basis at a time resolution of 1 minute.
