just a little note: - *sea_surface_wave_significant_height*Wave height is defined as the distance from a wave trough to the following wave crest. > > NOTE: the is the VERTICAL distance -- difference in elevation between the bottom of a trough and top of the crest. this wording sounds a lot like a horizontal distance -- a totally different concept. Anyone that words with waves knows this, of course, but if we're going to have definitpons they should be clear to lay people, too.
Significant wave height is a statistic computed from wave measurements collected during an > observation period that approximates to the wave height that would be > recorded visually by a human observer during that observation period. > > this is a bit tricky -- yes, that's what significant wave height means, but it is often (usually?) used now to mean the height of the highest third, perhaps that goes in the long name, but I think it should probably be in the description, as that's how it's actually measured/computed these days. -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [email protected]
