| A commercial low-resolution (0.5 cm−1)
Fourier Transform Spectrometer (FTS) has been modified and is used
for determining the total column XCO2 of the atmosphere by
analysing direct solar radiation. The spectrometer has a small
home-built solar tracker attached, so that it is a ready-to-use
instrument. The results are validated with temporally coinciding
on-site measurements taken with a high-resolution Total Carbon
Column Observing Network (TCCON) FTIR spectrometer. For the whole
comparison period of 5 months (26 measurement days) an agreement
with TCCON results of (0.12 ± 0.08)% is achieved. This
makes the spectrometer a promising candidate for a low-cost addition
to the TCCON core FTIR sites, especially suitable for locations with
limited infrastructure. An impressive mechanical and thermal
stability is proved, enabling the spectrometer for use in field
campaigns and for the monitoring of local sources. |
