This way the system should meet the demands and should be up to standard.

The selection of the sensors aims at longevity, reliability and accuracy. The results

from the test readings came up to the expectations and requirements of the system.

Especially the pressure readings have shown excellent accuracy.

The data processing via TCP/IP is another fundamental component for real time

data processing of the meteorological data. The use of the Ethernet/CF-Card mod-

ule also enables the feature of data transfer via FTP. Therefore the user can modify

the calibration factors and oﬀsets without the need to open the main program ﬁle.

Averages, minima, maxima, squared sums and number of measured data are pro-

vided to the system every minute in SI units. The pressure readings are important

to calculate the mixing ratio of the measured trace gases and will be added to TC-

CON’s database with its related solar spectra. Moreover you can draw conclusions

from standard deviation by consulting the squared sum and the number of mea-

sured data. Finally the data are added to data tables with a timestamp for archival

storage in order to ﬁnd out possible discrepancies in solar spectra.

There are still some parameters on the operational site which have to be determined,

for example at which wind speed the dome should be closed or at which time the

conditions are favorable for measurements. These parameters will result from fur-

ther operation and its experienced data.

After all, the weather station was built as an eﬃcient autonomous and easy to

use system. This system operates closely together with the other systems in the

container and provides the required data to built up a completely automatic mea-

surement system - the BGC FTIR-Container.
