Use argo_vars() to extract variable information from a vector of
Argo NetCDF files in the form of one row per variable. Use
argo_read_vars() for lower-level output from a single NetCDF file.
argo_vars(path, download = NULL, quiet = NA)A path relative to the root directory of
argo_mirror() or argo_cache_dir(). This value can also
be a data.frame with a file column (e.g., a global index as
returned by argo_global_meta() and others).
A logical vector indicating whether or not
a file should be downloaded. Defaults to the value of
argo_should_download(), which is TRUE for files that
do not exist in the cache.
Use FALSE to show which files are downloaded and for more
verbose error messages.
A tibble::tibble() with one row per variable and columns file,
name,size, dim, and att_* for variable attributes.
