This article introduces a new fully automated
FTIR system that is part of the Total Carbon Column Observing Network
(TCCON). It will provide continuous
ground-based measurements of column-averaged volume mixing ratio for
CO2, CH4 and several other greenhouse gases in the tropics.
Housed in a 20-foot shipping container it was developed as a transportable
system that could be deployed almost anywhere in the world. We describe the
automation concept which relies on three autonomous subsystems and their
interaction. Crucial components like a sturdy and reliable solar tracker dome
are described in detail. The automation software employs a new approach
relying on multiple processes, database logging and web-based remote control.
First results of total column measurements at Jena, Germany show that the
instrument works well and can provide parts of the diurnal as well as
seasonal cycle for CO2. Instrument line shape measurements with an
HCl cell suggest that the instrument stays well-aligned over several
months.
After a short test campaign for side by side intercomaprison with an existing
TCCON instrument in Australia, the system will be transported to its final
destination Ascension Island. |
