Validation of the NMIMET Analysis

The reliability of the NMIMET analysis methods for deriving wave statistics from visual observations of waves and winds has been extensively demonstrated by comparisons with measured data on a world-wide basis.

Detailed accounts of the development and validation of the analysis may be found in the references [24] - [27] and [36]. However it may be helpful here to present a selection of results indicating the level of reliability achieved by the program in terms of comparisons with instrumental and raw visual data from a number of locations in widely separated areas of the world.

Figure 5 - Selected Validation Results: Map of Locations.

Figure 5 shows the global distribution of the eight locations for which results are presented in terms of wave height distributions (Figure 6 to Figure 14) and wave period distributions (Figure 15 to Figure 23).
