The CO2 sensor is the Sensirion SCD30 (short 'scd' in the log). The 'central' station is a Gill MaxiMet GMX541. See this publication for more information.

The positions of the mentioned stations are listed in positions.csv in UTM 32U coordinates that were optimized from distance measurements between the points of interest taken in the field.
