Erratum: Heo, J.-H.; et al. Optimal Interpolation of Precipitable Water Using Low Earth Orbit and Numerical Weather Prediction Data. Remote Sens. 2018, 10, 436.

The Editorial Office of Remote Sensing wish to report an error in the aforementioned published paper [1]. The titles of Figures 5 and 6 as well as Table 3 were incorrect, which were originally:

Figure 5. For OI time period of 7 December 2016 00:00–03:00 UTC, (a–d) are background fields for four PW (TPW, BL, ML, and HL); (e–h) are observation data for four PW; and (i–l) are four OI PW fields.

Figure 6. Qualitative validation for OI time period of 7 December 2016 00:00—03:00 UTC. (a–d) are four OI-B PW fields; and (e–h) are four O-B PW data.

Table 3. Quantitative validation over the period 7 January 2016 00:00—8 January 2016 00:00 UTC. (Left) PW RMSE; (Right) PW bias. The percentages in brackets indicate improvements made over background through the application of OI.

The correct titles of the figures and table are as follows:

Figure 5. For OI time period of 12 July 2016 00:00—03:00 UTC: (a–d) are background fields for four PW (TPW, BL, ML, and HL); (e–h) are observation data for four PW; and (i–l) are four OI PW fields.

Figure 6. Qualitative validation for OI time period of 12 July 2016 00:00—03:00 UTC: (a–d) are four OI-B PW fields; and (e–h) are four O-B PW data.

Table 3. Quantitative validation over the period of 1 July 2016 00:00—1 August 2016 00:00 UTC: (Left) PW RMSE; and (Right) PW bias. The percentages in the brackets indicate improvements made over the background through the application of OI.

We apologize for any inconvenience caused to the readers by this change. The change does not affect the scientific results. The manuscript will be updated and the original version will remain available on the article webpage.
