Cell highlighting that was originally included in Table 1 was not typeset in the original version. This has been replaced with indicators (*) against the relevant data points so that these labels are now shown in the HTML and pdf versions of the article. The table caption has also been updated to reflect this change, with the phrase “Grey shaded research flights contain soundings with at least one issue discussed in the following paragraphs” replaced with “A * following the number of dropsonde launches indicates research flights containing soundings with at least one issue discussed in the following paragraphs.”
