TABLE 2.
List of the variables used as drivers to estimate gross primary production (GPP) and ecosystem respiration (RECO)
| Variable | Time resolution | GPP | RECO |
|---|---|---|---|
| Measured | Half hourly | SW_IN a | TA |
| SW_IN_POT | TS | ||
| VPD | SWC | ||
| TA | WS | ||
| SWC | |||
| WS | |||
| Calculated | Half hourly | SW_IN_POT First derivative | Cos WD |
| Cos WD | Sin WD | ||
| Sin WD | |||
| Daily | Daily average SW_IN_POT | Sin(DOY) | |
| Daily average SW_IN_POT first derivative | Cos(DOY) | ||
| GPP prox | Net ecosystem exchange night |
a
SW_IN is then used both as driver and as single input in the GPP subnetwork for the product with the LUE.
