Combine many netCDFs into one file per year — nc_merge_all_sites_by

Merges model outputted netCDF files by the time steps specified in a pecan settings file.

Usage

nc_merge_all_sites_by_year(
  model.outdir,
  nc.outdir,
  ens.num,
  site.ids,
  start.date,
  end.date,
  time.step = "1 year",
  cores = 1
)

Arguments

model.outdir: character: path to the folder that contains model outputs.
nc.outdir: character: physical path to the folder that contains the merged netCDF files.
ens.num: numeric: number of ensembles for the model run.
site.ids: numeric or character: vector of site ids across locations.
start.date: date or character in YYYY-MM-DD format: start date of the model run.
end.date: date or character in YYYY-MM-DD format: end date of the model run.
time.step: character: time step of the model run. Default is 1 year.
cores: numeric: the number of CPUs for the parallel computation. Default is 1.

Value

character: file paths to the merged netCDF files.

Details

The function is only tested for SIPNET model runs that were run with state data assimilation enabled. Please make sure you have the same netCDF formats if you want to proceed with different models. We could also have more functions that deal with different dimensions (e.g., by site instead of by year).
