analyzemerge_gaugeir: Quality assurance/quality checking of streamflow time series

In messamat/globalIRmap: What the Package Does (One Line, Title Case)

Description

Record of quality-checking procedure which aimed to ensure the validity of zero-flow readings and the flow intermittence class assigned to each gauge (i.e., perennial or non-perennial).

Usage

analyzemerge_gaugeir(
  in_GRDCgaugestats,
  in_GSIMgaugestats,
  yearthresh,
  in_gaugep,
  inp_resdir,
  plotseries = FALSE
)

Arguments

in_GRDCgaugestats	list of data.tables of intermittency statistics, output from comp_GRDCdurfreq applied to all GRDC gauging stations.
in_GSIMgaugestats	list of data.tables of intermittency statistics, output from comp_GSIMdurfreq applied to all GSIM gauging stations.
yearthresh	(integer) minimum year from which to analyze discharge record.
in_gaugep	sf object of gauging stations.
inp_resdir	(character) path to the results directory in which to create folder and write output plots
plotseries	(logical) whether to create plots of streamflow time series for gauging stations that are non-perennial only in winter or within 3 km from the coast.

Details

For details on the QA/QC procedure, see Supplementary Information at https://www.nature.com/articles/s41586-021-03565-5. The reason for station exclusion is also presented in an interactive online map at https://messamat.github.io/globalIRmap/ in the Data and methods/Reference streamflow gauging stations tab.

Value

list of two data.tables.

• A data.table listed as 'data' which contains the collated outputs from comp_GRDCdurfreq andcomp_GSIMdurfreq for the stations that were not excluded through this QA/QC process.

• A data.table listed as flags, listing all stations excluded from further analysis and the reason their exclusion.
