B.2. STRUCTURE OF THE BLOCK WITH METEOROLOGICAL DATA
In the case when the instrument is working in a monitoring station which contains also the components
for the meteorological measurements (temperature, pressure, humidity, wind speed and its direction),
the data coming from them are added by SvanPC+ software to all files with the data from SVAN 958.
The structure of such data block is presented in the Tab. B.2.1.
