XBT and CTD pairs dataset Version 2

The XBT/CTD pairs dataset (Version 2) contains additional datasets and updated datasets from the Version 1 data. Version 1 data was used to update the calculation of 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 Technology, 30, 1195–1225, doi:10.1175/JTECH-D-12-00127.1. http://journals.ametsoc.org/doi/abs/10.1175/JTECH-D-12-00127.1
Version 2 contains 1,188 pairs from seven datasets that add to Version 1 which contains 4,115 pairs from 114 datasets. There are also 10 updated datasets included in Version 2. The updates apply to the CTD depth data in the Quality Controlled version of the 10 datasets. The 10 updated Version 2 datasets should be used in preference to the copies in Version 1. Note that future versions of the XBT/CTD pairs database may supersede this version. Please check more recent versions for updates to individual datasets.
Each dataset contains the scientifically quality controlled version and (where available) the originator's data. The XBT/CTD pairs are identified in the document 'XBT_CTDpairs_metadata_V2.csv'.
Although the XBT data in the additional datasets was collected after 2008, much of the probes in the ss2012t01 dataset were manufactured during the mid-1980s.
