Jülich JUE

50°54‘ N / 6°25‘E

Altitude: 98 m a.s.l.

Tower height: 120 m

Measurements of CO2, CH4, N2O and CO are made on the Jülich tower at three heights (50 m, 80 m, 120 m). Each height is sampled sequentially for the duration of 5 minutes.

Measurements of CO2 and CH4 are performed by a Picarro G2301 analyser using cavity ring-down spectroscopy (CRDS). N2O and CO are measured by a Los Gatos LGR 30-EP analyser.

Furthermore, radon concentrations are also monitored at the Jülich tower.

The following instrumentation is used to record the meteorological parameters at the three sampling heights:

• Air temperature and humidity: Vaisala HMP155
• Wind direction and speed: Thies Ultrasonic Anemometer 2D UA2D
• Precipitation: Eigenbrodt RS85
• Air pressure: Vaisala PTB330
• Global radiation: Kipp & Zonen CM6B

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