Usage

CLI modules

These functions are meant to be called via the CLI.

device

Processing command for different devices

This module is part of the polair package and provides functionality for processing different devices.

The device command processes data from other instruments than noseboom and t-bird.

polair device -f <flight number> -c <config file> -i <instrument>  -p <platform>

Options for instruments are mcpc, partector, partector_dms, kt19, and radiation. Platform p is optional with default being polar6, add if platform is tbird.

noseboom

Noseboom processing command.

This module is part of the polair package and provides functionality for noseboom processing.

The noseboom command determines the basic meteorological parameters from the calibrated raw data of the noseboom, which can be mounted at the nose of Polar 5 and 6. Adiabatic corrections are used and the wind components are determined.

polair noseboom -f <flight number> -c <config file>

preprocessing

Preprocessing command to convert all data to physical, calibrated values

This module is part of the polair package.

title: preprocessing.py
author: Laura Köhler
institution: Alfred-Wegener-Institut, Bremerhaven, Germany
date: 2026-04-17

The preprocessing command converts all data in physical quantities. If necessary and provided, it calibrates the data. Finally, they are interpolated on common (default 100 Hz) time stamps. The command also checks for data gaps and sampling errors which are noted in the log file. The calibrated raw data will be saved as a netCDF file. The location needs to be specified in the configuration file of the campaign.

polair preprocessing -f <flight number> -c <config file>

tbird

T-Bird processing command

This module is part of the polair package and provides functionality for processing the T-Bitd data.

title: tbird.py
author: Laura Köhler
institution: Alfred-Wegener-Institut, Bremerhaven, Germany
date: 2026-04-17

The tbird command determines the meteorological parameters from the T-Bird similar to the noseboom command.

polair tbird -f <flight number> -c <config file>
