CO2.control: Simple function that controls how the CO2 concentration measurements influence the estimation of the flux rates for the other gases.
Description
Just takes it arguments and hands them over to the argument co2ntrol in flux.Usage
CO2.control(CO2.columns = c("CO2ppm", "CO2Code"), trans.out = TRUE, range.lim = 30, min.allow = 3)Arguments
CO2.columns
A character vector of length 2 giving the names of the columns that contain the CO2 concentration measurements and the CO2 quality flag of the measurement device (see flux for details). trans.out
Logical. Shall the CO2 outliers be transfered to flux.odae so that gas concentration measurements that caused CO2 outliers are not included in the optimation procedure anymore? range.lim
Numeric value. The minimum ppm range for CO2 that is acceptable. For details see same argument at flux. min.allow
Integer between 3 and the number of concentration measurements per chamber placement. For details see min.allowed at flux. Value
- Returns a list with arguments that are used within
flux to control the influence of CO2 concentration measurements on the flux estimation of other ghg. See arguments section for details.
Details
The idea behind co2ntrol in flux is that the CO2 concentration measurements might serve as a further check on the integrity of the chamber measuremnt in the field. For details see flux. With trans.out = FALSE it is possible to omit the transfer of CO2 outliers to the rest of the optimization procedure whilst maintaining the quality flag on leakage.See Also
