CO2 concentration
co2_conc_missing.Rd
CO2 concentration with measurements meta data, with missing data.
Format
A tibble with 668 rows and 13 variables
- datetime
Datetime at which CO2 concentration was recorded.
- temp_air
Air temperature inside the flux chamber in Celsius.
- temp_soil
Ground temperature inside the flux chamber in Celsius.
- conc
CO2 concentration in ppm.
- PAR
Photosynthetically active radiation inside the chamber in micromol/s/sqm.
- turfID
Unique ID of the turf in which the measurement took place.
- type
Type of measurement: ecosystems respiration (ER) or net ecosystem exchange (NEE).
- start
Datetime at which the measurement was started.
- end
Datetime at which the measurement ended.
- fluxID
Unique ID for each flux.
- n_conc
Number of data point per flux.
- ratio
Ratio of n_conc over length of the measurement (in seconds).
- flag
Data quality flags.
