FluxSynthU: Suite of functions to analyze eddy covariance data

View source: R/FS_fExtractAllCriticalDates.R

After calculating GPPsat using 'FS_fCalculateGPPandNEESatParameters', this function will extract critical dates from the GPPsat time series. Additionally, this function will calculate start and end of winter (SOW/EOW) based on the period in which ecosystems no longer accumulate C (GPP-free period), using cumulative GPP as the flux parameter.

)

`inpath_GPPsat`	character string, navigate to the directory containing GPPsat and associated fit parameters
`inpath_complete_output`	character string, navigate to the directory containing stacked complete output datasets (specific formatting required)
`outpath_critdates`	character string, specify path to where you'd like to export a dataframe of critical dates (includes all sites on the same df)
`outpath_plots`	character string, specify path to where you'd like to export figures
`site.meta`	dataframe, site metadata file contained in FluxSynthU
`span`	numeric, set the span for time series smoothing (defaults to 0.075)
`create.plots`	logical, if TRUE (default) exports 4 figures
`export.files`	logical, if TRUE (default) exports dataframes as text files in the outpath directory.
`batch_process`	logical, if TRUE, batch processes all sites within the inpath directory (defaults to FALSE).
`exclude_bad_yrs`	logical, if TRUE, excludes user defined years from the analysis (defaults to FALSE).
