Get all the files defined by a catalogue

This function takes a catalogue of ERA5 data (typically obtained from era5() and filtered with set_date_range()) and returns the corresponding file paths on gadi's filesystem.

Usage

get_files(catalogue)

Arguments

catalogue

A data.table containing ERA5 catalogue information. Typically obtained by subsetting the output of era5() and applying set_date_range().

Value

A data.table with columns:

• variable: The ERA5 variable name

• aggregation: The temporal aggregation (e.g., "monthly", "hourly")

• range_start: Start date of the requested range

• range_end: End date of the requested range

• files: A list column containing character vectors of file paths for each combination of variable, aggregation, and date range. Files that don't exist will be NA.

Examples

if (FALSE) { # \dontrun{
# Get catalogue and filter for specific variable and dates
catalogue <- era5() |>
  subset(variable == "2t") |>
  set_date_range("2020-01-01", "2020-12-31") |>
  get_files(catalogue)
} # }
