Parameters
|
CO2 flux
|
| Observation period |
2022/05/27 - 2022/12/25
|
| Location |
34º 57' 49" N, 135º 59' 40" E
|
| Altitude |
Elevation: 190.0 m;
Observational altitude: 219 m |
| Measurement method |
The CO2 flux measurements were conducted using eddy covariance (EC) and true eddy accumulation technique (TEA).
|
| Calculation method |
The TEA CO2 flux was simulated using the 10 Hz EC data following the protocols for TEA flux measurements. Two types of simulations were carried out: one with the wind threshold and one without.
