N2 - In Hill et al. (2016), there were errors in the reporting of covariance localization half-widths, both in the horizontal and vertical. The horizontal half-widths were reported as 600 and 300 km and the vertical half-widths were reported as 0.075 and 0.025 km for the outermost and inner domains, respectively. These half-width values of the Gaspari-Cohn localization function (Gaspari and Cohn 1999) come from a Data Assimilation Research Testbed (Anderson et al. 2009) namelist, which was incorrectly interpreted. The horizontal half-widths should have been calculated as the product of the namelist cutoff value (e.g., 0.05) and radius of Earth in kilometers. The vertical localization half-widths should have been calculated as the product of the cutoff value and normalization distance, which in this instance was 10 000 m. Therefore, the horizontal localization half-widths should be 950 and 320 km, and the vertical half-widths 1.5 and 0.5 km, for the outer and nested domains, respectively. These reporting errors were only typographical in nature and in no way impacted the results therein.
