| Zusammenfassung |
| The Total Carbon Column Observing Network (TCCON) provides total column
measurements of various atmospheric trace gases like CO2, CH4, CO, and N2O at high
precision. At each site, the measurements are performed with Bruker IFS125HR Fourier
Transform Infrared (FTIR) spectrometers that are operated by individual research groups.
Instrument setup, operation and data processing follows common standards and best practices
defined by the TCCON community.
Most TCCON instruments are built for a specific location and remain there after initial
setup. However, the TCCON instrument by the Max Planck Institute for Biogeochemistry
has been designed to be mobile and to be able to operate in many regions of the
world. The FTIR instrument has been built into a 20-foot shipping container that
can easily be transported over land and sea at reasonable cost. Once it is set up, it
can run fully automatically for several months without maintenance or operator
intervention.
To verify that the instrument can still achieve the expected measurement quality after
transport and setup at a remote site, it was transported from Germany to Wollongong,
Australia, for a test campaign. The instrument remained at Wollongong from June to
December 2010. During this time, it measured simultaneously with another TCCON
instrument at the University of Wollongong. This study presents results from these first
co-located measurements of two independently constructed TCCON instruments. |
