This section focuses on the accuracy evaluation and comparison of the selected six P products against measured P values using the commonly used statistic indices. The results were then compared with the accuracy evaluation based on water budget closure in Section 3.2 and Section 3.3 to show the difference these two kinds of methods for assessment of HDPs. Because these kinds of methods describe the accuracy of HDPs from perspective of data error for each budget component (satellite estimate values against measured values) and water budget closure for all budget components, respectively. Two methods for the latter, the budget closure residual considering fully HDPs in Section 3.2 and the method considering both HDPs and the measured values in Section 3.3, were considered in this study.
