In the original article, there was an error in the simplification of Equations (8) and (9) to Equation (10). A correction has been made to Equation (10):
In the original article, there were mistakes in Figures 5 and 8 as published. The analytical uncertainty estimates were derived wrongly. The corrected Figures 5 and 8 appear below.
Figure 5
Figure 8
The corrected Figure 5 requires update of the description in the text. A correction has been made to the Results and Discussion section, Experiment A (Fendt site), paragraph 2:
“[…] With the exception of sections 5, 9 and 10, all sections showed good agreement between the expected and measured uncertainty of soil moisture. […]”
The corrected Figure 8 requires update of the description in the text. A correction has been made to the Results and Discussion section, Experiment B (Selhausen site), paragraph 5:
“[…] However, the expected soil moisture estimation uncertainty using Selhausen site conditions (Figure 8) were similar to the overall uncertainty as expressed by the RMSE when only 3 measurements were used (0.032 m3/m3). This is undesirable and suggests the need for more aggregation. When nine measurements were aggregated, the average uncertainty due to uncertain neutron measurements decreased to 0.017 m3/m3 irrespective of aggregation strategy. […]”
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
