The column observation, in combination with the existing and growing surface mea-

surements, will improve estimates of surface ﬂux of greenhouse gases, allowing im-

proved predictions of their future concentrations, and ultimately climate. In addition

to their direct use for carbon ﬂux studies, TCCON measurements will be used to val-

idate satellite column measurements for the Orbitting Carbon Observatory (OCO),

Scimatchy and the Global Greenhouse Observation by Satelite (GOSAT).

Several of the TCCON sites have been either fully or partly funded for validation of

the NASA OCO satellite. To provide useful constraints for the global carbon budget

the measurements must achieve a precision approaching 0.1%.

Within my diploma thesis my work will account for ground-based FTIR measure-

ments by making a contribution for building up a fully automatic measurement

system - the BGC-FTIR-Container.

Figure 1.3: BGC-FTIR-Container

This container will likely takes up work on Ascension Island in the ﬁrst quarter of

2009 for measuring CO

and CH

by means of the solar spectrum for carrying these

data forward into TCCON’s database. The ireland with its capital Georgetown is

situated in the south atlantic ocean, shown in Fig. 1.2, 7 °56’ 38" South and 14

°21’ 51" West. It has tropical climate and a population of 1100 people inhabiting

an area of 91 km
