CO2 flux

CH-INO@CH-OE2

At site CH-OE2, from CH-INO instruments installed on a separate mast close to the main CH-OE2 mast. Measured using an open-path IRGA75 (LI-7500). Note the differences in the cumulative CO2 curve in comparison to CH-OE2. The cumulative curve shows more and earlier CO2 uptake, which potentially indicates increased uptake due to LI-7500 self-heating.

CO2 flux

CH-LAE

SRP (AS): CO2 fluxes with QCF (removed flag =2). Since beginning of May, the flow-rate was very low, I think because of the filter.

CH-LAS

CO2 flux

CH-OE2

At site CH-OE2, instruments installed on the main CH-OE2 mast. Measured using an enclosed-path IRGA72 (LI-7200). Note the differences in the cumulative CO2 curve in comparison to CH-INO.
