argo_read_traj: Read Argo trajectories

In ArgoCanada/argodata: Locate, Download, and Read Argo Ocean Float Data

Description

Use argo_read_traj_*() functions to extract trajectory information from a previously-downloaded Argo NetCDF file.

Usage

argo_read_traj_measurement(file, vars = NULL, quiet = FALSE)

argo_read_traj_cycle(file, vars = NULL, quiet = FALSE)

argo_read_traj_param(file, vars = NULL, quiet = FALSE)

argo_read_traj_history(file, vars = NULL, quiet = FALSE)

Arguments

file	A previously downloaded Argo NetCDF file (e.g., using argo_download()).
vars	A vector of variable names to include. Explicitly specifying vars can lead to much faster read times when reading many files.
quiet	Use FALSE to stop for malformed files, NA to silently warn for malformed files, or TRUE to silently ignore read errors when possible.

Value

A tibble::tibble() with

• argo_read_traj_measurement(): one per measurement.

• argo_read_traj_cycle(): one per cycle.

• argo_read_traj_param(): one per parameter.

• argo_read_traj_history(): one row per history entry.

Examples

traj_file <- system.file(
  "cache-test/dac/csio/2900313/2900313_Rtraj.nc",
  package = "argodata"
)

argo_read_traj_measurement(traj_file)
argo_read_traj_cycle(traj_file)
argo_read_traj_param(traj_file)
argo_read_traj_history(traj_file)
