ctdam.parser.read_ctd_data module

ctdam.parser.read_ctd_data.create_array_coords(raw_file_data, data_length=0)

Sets the datasets coordinates.

Parameters:

raw_file_data (SeabirdDataFile) – The raw data source

Return type:

dict

ctdam.parser.read_ctd_data.create_array_attrs(raw_file_data)

Sets the datasets attributes.

Parameters:

raw_file_data (SeabirdDataFile) – The raw data source

Return type:

dict

ctdam.parser.read_ctd_data.sorting_parameters(sensor_pairs, rule=None)

Returns sorted parameter for conversion.

ctdam.parser.read_ctd_data.parse_oxygen_data(name, data, cnv)

Returns oxygen data in umol/kg

Return type:

ndarray

ctdam.parser.read_ctd_data.read_cnv(path_to_cnv_file, only_header=False)

Parse Seabird .cnv data to cf-compliant xarray Dataset.

Parameters:

• path_to_cnv_file (Path | str) – The path to the .cnv file

• only_header (bool) – Whether to only parse the header information

Return type:

Dataset

ctdam.parser.read_ctd_data.build_sensor_pairs(hex_file, coefficients)

Match XMLCON sensors to their raw HEX channels.

Channels 1-5 correspond to f0-f4. Channels 6-13 correspond to v0-v7.

Return type:

list[tuple[str, ndarray]]

ctdam.parser.read_ctd_data.read_hex(path_to_hex_file)

Parse Seabird .hex data to cf-compliant xarray Dataset.

Parameters:

path_to_cnv_file (Path | str :) – The path to the .hex file

Return type:

Dataset

ctdam.parser.read_ctd_data.sst2xarray(input_path, delimiter=' ')

Read CTD data from an SST .TOB data file and create an Xarray Dataset.

Parses SST .TOB files directly into a common Xarray structure with: - “scan” dimension for each measurement row - Data variables incl. metadata - Provenance and common metadata tracking

Based on a MATLAB script written by Johanna Grote and Jens Faber.

Parameters:

• input_path (Path | str) – The path to the .TOB file

• delimiter (str) – The data file delimiter (default: “ “)

Return type:

Dataset

ctdam.parser.read_ctd_data.parse(file_path, downcast_only=False)

Parse different file types to a cf-compliant xarray Dataset.

Can handle Seabirds .cnv and .hex file formats and Sea&Suns .TOB file format.

Parameters:

file_path (Path | str) – The path to the ctd data file

Return type:

Dataset
