Abstract:
The data describes plant gas exchange dynamics (CO2, H2O) including stomatal conductance and water use efficiency of Pinus halepensis seedlings exposed to drought and increasing temperatures under either ambient (c. 400 ppm) or elevated (c. 900 ppm) atmospheric [CO2]. Measured in a scientific glasshouse facility at KIT IMK-IFU Garmisch-Partenkirchen, Germany, via seperately controlled growth chambers setup.

Change history:
2022-02-07T12:15:29 – The parameter VPD was corrected. It was multiplied *10 and the unit was changed to kPa, e.g. value changed from 0.1 hPa to 1 kPa. The reason was a wrong recalculation, which was corrected now.
