Manually calculated CO2 fluxes for testing purpose. df_short and record_short were used, with a zhao18 fit.
Format
A tibble with 6 rows and 11 variables
- f_fluxid
Unique ID for each flux.
- f_slope_tz
Slope of C(t) at t zero.
- f_temp_air_ave
Air temperature inside the flux chamber in Celsius averaged over the flux measurement.
- f_flux
CO2 flux in mmol/sqm/hour.
- PAR
Photosynthetically active radiation inside the chamber in micromol/s/sqm averaged over the flux measurement.
- temp_soil
Ground temperature inside the flux chamber in Celsius averaged over the flux measurement.
- turfID
Unique ID of the turf in which the measurement took place.
- type
Type of measurement: ecosystems respiration (ER) or net ecosystem exchange (NEE).
- f_start
Datetime at which the measurement started.
- temp_fahr
Air temperature inside the flux chamber in Fahrenheit averaged over the flux measurement.
- temp_kelvin
Air temperature inside the flux chamber in Kelvin averaged over the flux measurement.
