Karlsruhe KIT
49°06' N / 8°26' E
Altitude: 110 m a.s.l.
Tower height: 200 m
Samples of trace gases are taken at four heights (30 m, 60 m, 100 m and 200 m) with a measurement duration of 5 minutes per measurement changing between the 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 an Los Gatos 30-EP measuring device by the end of 2016.
Additionally C14 samples are collected and sent to the Radiocarbon Laboratory for analysis (http://www.icos-infrastruktur.de/en/icos-d/komponenten/labore/radiokohlenstofflabor-heidelberg/). The 14C isotope is an indicator of the proportion of fossil fuels in CO2.
The meteorological parameters are observed using the following instruments:
- Air temperature and humidity: Vaisala HMP155
- Wind direction and speed: Thies Ultrasonic Anemometer 2D UA2D
- Air pressure: Vaisala PTB330
- Global radiation: Kipp & Zonen CM6B
These data are supplied on a continuous basis at a time resolution of 1 minute.
Data can be downloaded from the ICOS Carbon Portal: https://www.icos-cp.eu/
