In 2009 a new FTIR container with a Bruker®  IFS 125HR has been set up on the Campus North of KIT. The container has been made by Impres® GmbH, Bremen, and is prepared for automatic operation. The spectrometer is operated mainly in the near infrared (NIR) spectral domain to measure CO2 by remote sensing as precise as possible.

An FTIR is operated at Karlsruhe

  • to measure precisely greenhouse gases, mainly CO2, CH4 and N2O;
  • to improve the instrumentation and measurement accuracy;
  • to compare data with in-situ measurements made on a tall tower at the site;
  • to validate satellite data. Because of the flat terrain the site is favorable to do so.
