CO2 concentration — co2_conc_missing • fluxible

CO2 concentration with measurements meta data, with missing data.

Usage

co2_conc_missing

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.
