Voyage data for the manuscript "Ship-based lidar evaluation of Southern Ocean clouds in the storm-resolving general circulation model ICON, and the ERA5 and MERRA-2 reanalyses"

This repository contains voyage data for the manuscript “Ship-based lidar evaluation of Southern Ocean clouds in the storm-resolving general circulation model ICON, and the ERA5 and MERRA-2 reanalyses” (DOI: 10.5281/zenodo.14071808), which have not already been published elsewhere. It includes ceilometer, radiosonde and surface observations collected by the University of Cantebrury, Christchurch, Aotearoa/New Zealand and collaborators on the following Southern Ocean voyages [abbreviation, ship name (time period, track)]:

• AA15-16: RSV Aurora Australis (22 October 2015–22 February 2016, Hobart, Tasmania, AU–East Antarctica–Macquarie Island–Hobart, Tasmania, AU)
• HMNZSW16: HMNZS Wellington (20 November 2016–20 December 2016, Auckland, NZ–Ross Sea–Auckland, NZ)
• NBP1704: RV Nathaniel B. Palmer (11 April 2017–14 June 2017, Lyttelton, NZ–Terra Nova Bay–Lyttelton, NZ)
• TAN1502: RV Tangaroa (20 January 2015–12 March 2015, Wellington, NZ–Ross Island–Wellington, NZ)
• TAN1702: RV Tangaroa (16 March 2017–1 April 2017, Wellington, NZ–Campbell Plateau–Wellington, NZ)

See also Table 1 in the manuscript for more information.

Included are data from the following instruments (abbreviation, instrument name, file format):

• chm15k: Lufft CHM 15k ceilometer (NetCDF)
• cl51: Vaisala CL51 ceilometer (DAT)
• rs: Radiosonde profiles (MATLAB and InterMet Systems)
• surf: Surface observations from the ship information system and weather instruments (CSV, MATLAB and NetCDF)

The ZIP archives in this repository are named “voyage abbreviation_instrument.zip”.

The ceilometer files can be processed with the ALCF (https://alcf.peterkuma.net, DOI: 10.5281/zenodo.3774785, and https://github.com/alcf-lidar/alcf). The CL51 files can be converted to NetCDF with cl2nc (https://github.com/peterkuma/cl2nc, DOI: 10.5281/zenodo.4409715). The InterMet Systems radiosonde files can be converted to NetCDF with rstool (https://github.com/peterkuma/rstool, DOI: 10.5281/zenodo.5040217).
