Duke FACE Micrometeorological Data

Precipitation, Net radiation, and PAR data files (1998, rings 4 and 5):
First four columns show precipitation (mm) and net radiation (W/m^2).
Ring 4 measures overstory precipitation (po), and ring 5 measures throughfall (pt).
The last data column shows PAR (millimol/m^2*s).

Air temperature, Relative Humidity, SVP, and VPD (r1 - r6):
Data columns are organised by ring number.
For each ring there is:
- Temperature (Degrees C)
- Relative humidity (absolute values)
- SVP (Saturated Vapor Pressure - kPa)
- VPD (Vapor Pressure Deficit - kPa)
measurements are done at 2/3 of canopy height

Note: gap-filled data are available for some variables and years.
