XBT and CTD pairs dataset Version 1

The XBT/CTD pairs dataset (Version 1) is the dataset used to calculate the historical XBT fall rate and temperature corrections presented in Cowley, R., Wijffels, S., Cheng, L., Boyer, T., and Kizu, S. (2013). Biases in Expendable Bathythermograph Data: A New View Based on Historical Side-by-Side Comparisons. Journal of Atmospheric and Oceanic Tech... more

Data is sourced from the World Ocean Database, NOAA, CSIRO Marine and Atmospheric Research, Bundesamt für Seeschifffahrt und Hydrographie (BSH), Hamburg, Germany, Australian Antarctic Division. Original and raw data files are included where available. Quality controlled datasets follow the procedure of Bailey, R., Gronell, A., Phillips, H., Tanner, E., and Meyers, G. (1994). Quality control cookbook for XBT data, Version 1.1. CSIRO Marine Laboratories Reports, 221. Quality controlled data is in the 'MQNC' format used at CSIRO Marine and Atmospheric Research. The MQNC format is described in the document 'XBT_CTDpairs_descriptionV1.pdf'. Note that future versions of the XBT/CTD pairs database may supersede this version. Please check more recent versions for updates to individual datasets.

About this Project

3.2 ACCSP-Climate Variability and Change

The ACCSP provides quality science-based information about the likely changes in sea level, storm surge and extreme weather events so that decision makers can manage the risks associated with, and minimise the consequences of, climate change. Understanding how and why the ocean is changing is critical for improving sea level rise projections. Impro... more

Oceanographic temperature dataset

A collection of historical oceanographic temperature data used to calibrate or correct a historical archive. In this case, the corrections are applied to XBT data.


Data is obtained from various historical CTD (conductivity, temperature, depth) and XBT (expendable bathythermograph) instruments.
