sea_surface_wave_maximum_crest_height
Unit: m
Unit ref: ULAA
The crest is the highest point of a wave. Crest height is the vertical distance between the crest and the calm sea surface. Maximum crest height is the maximum value measured during the observation period.
sea_surface_wave_maximum_trough_depth
Unit: m
Unit ref: ULAA
The trough is the lowest point of a wave. Trough depth is the vertical distance between the trough and the calm sea surface. Maximum trough depth is the maximum value measured during the observation period.
sea_surface_wave_maximum_height
Unit: m
Unit ref: ULAA
Wave height is defined as the vertical distance from a wave trough to the following wave crest. The maximum wave height is the greatest trough to crest distance measured during the observation period.
sea_surface_wave_significant_height
Unit: m
Unit ref: ULAA
GRIB: 100
Significant wave height is a statistic computed from wave measurements and corresponds to the average height of the highest one third of the waves, where the height is defined as the vertical distance from a wave trough to the following wave crest.
sea_surface_primary_swell_wave_significant_height
Unit: m
Unit ref: ULAA
Swell waves are waves on the ocean surface and are the low frequency portion of a bimodal wave frequency spectrum. The primary swell wave is the most energetic swell wave. Significant wave height is a statistic computed from wave measurements and corresponds to the average height of the highest one third of the waves, where the height is defined as the vertical distance from a wave trough to the following wave crest.
sea_surface_secondary_swell_wave_significant_height
Unit: m
Unit ref: ULAA
Swell waves are waves on the ocean surface and are the low frequency portion of a bimodal wave frequency spectrum. The secondary swell wave is the second most energetic wave in the low frequency portion of a bimodal wave frequency spectrum. Significant wave height is a statistic computed from wave measurements and corresponds to the average height of the highest one third of the waves, where the height is defined as the vertical distance from a wave trough to the following wave crest.
sea_surface_wave_mean_height_of_highest_tenth
Unit: m
Unit ref: ULAA
Wave height is defined as the vertical distance from a wave trough to the following wave crest. The height of the highest tenth is defined as the mean of the highest ten per cent of trough to crest distances measured during the observation period.
sea_surface_swell_wave_significant_height
Unit: m
Unit ref: ULAA
GRIB: 105
Swell waves are waves on the ocean surface and are the low frequency portion of a bimodal wave frequency spectrum. Significant wave height is a statistic computed from wave measurements and corresponds to the average height of the highest one third of the waves, where the height is defined as the vertical distance from a wave trough to the following wave crest.
sea_surface_wave_mean_height
Unit: m
Unit ref: ULAA
Wave height is defined as the vertical distance from a wave trough to the following wave crest. The mean wave height is the mean trough to crest distance measured during the observation period.
sea_surface_wind_wave_significant_height
Unit: m
Unit ref: ULAA
GRIB: 102
Wind waves are waves on the ocean surface and are the high frequency portion of a bimodal wave frequency spectrum. Significant wave height is a statistic computed from wave measurements and corresponds to the average height of the highest one third of the waves, where the height is defined as the vertical distance from a wave trough to the following wave crest.
