Use argo_meta_*() functions to extract information from Argo meta
NetCDF files. Use argo_read_meta_*()
to extract information from a single previously-downloaded NetCDF file.
Using argo_info() on meta files is also useful for extracting general
float information.
argo_meta_config_param(path, download = NULL, quiet = NA)
argo_meta_missions(path, download = NULL, quiet = NA)
argo_meta_trans_system(path, download = NULL, quiet = NA)
argo_meta_positioning_system(path, download = NULL, quiet = NA)
argo_meta_launch_config_param(path, download = NULL, quiet = NA)
argo_meta_sensor(path, download = NULL, quiet = NA)
argo_meta_param(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
argo_meta_config_param(): one row per file per configuration parameter and
columns file, n_config_param, n_missions, config_parameter_value,
and config_parameter_name.
argo_meta_missions(): one row per file per mission and columns file,
n_missions, config_mission_number, and config_mission_comment.
argo_meta_trans_system(): one row per file per transmission system
and columns file, n_trans_system, trans_system, trans_system_id,
and trans_frequency.
argo_meta_positioning_system(): one row per file per positioning
system and columns file, n_positioning_system, and
positioning_system.
argo_meta_launch_config_param(): one row per file per launch
configuration parameter and columns file, n_launch_config_param,
launch_config_parameter_name, and launch_config_parameter_value.
argo_meta_sensor(): one row per file per sensor and columns
file, n_sensor, sensor, sensor_maker, sensor_model,
and sensor_serial_no.
argo_meta_param(): one row per file per parameter and columns file,
n_param, parameter parameter_sensor, parameter_units,
parameter_resolution, predeployment_calib_equation,
predeployment_calib_coefficient, and predeployment_calib_comment.
