Comumn C: pCO2 in March 2019
Column D: CO2 emission (FCO2) in March 2019
Column E: Date and time of 2nd sampling campaign in May 2019
Comumn F: pCO2 in May 2019
Column G: CO2 emission (FCO2) in May 2019
Column H: Date and time of 3rd sampling campaign in July 2019

Column J: CO2 emission (FCO2) in July 2019 
Column K: Date and time of 4th sampling campaign in August 2019
Comumn L: pCO2 in August 2019
Column M: CO2 emission (FCO2) in August 2019 
Column N: Date and time of 5th sampling campaign in October 2019
Comumn O: pCO2 in October 2019
Column P: CO2 emission (FCO2) in October 2019
