Code Table 4.2 : new ocean wave parameters

[sebvi]

Initial request

In the context of the development of its wave model, ECMWF is requesting new ocean wave parameters which are variations of how the maximum individual wave (or crest) height is computed.

Amendment details

ADD new entries to Code Table 4.2	Name	discipline	category	number	units
Envelop maximum individual wave height	10	0	93	m
Time domain maximum individual crest height	10	0	94	m
Time domain maximum individual wave height	10	0	95	m
Space time maximum individual crest height	10	0	96	m
Space time maximum individual wave height	10	0	97	m

25-April-meeting: (1)Sebastian to add the relevant paper for reference to the GitHub; to approach the wave experts in ECMWF for definitions (2)Jeff proposes to add notes to the new ocean wave parameters

[sebvi]

The detailed description of the parameters proposed can be found in the appendix section of the following publication:

Francesco Barbariol, Jean-Raymond Bidlot, Luigi Cavaleri, Mauro Sclavo, Jim Thomson, Alvise Benetazzo maximum wave heights from global model reanalysis Progress in Oceanography (IF4.08), Pub Date : 2019-07-01, DOI: 10.1016/j.pocean.2019.03.009

In particular, proposed parameters 94, 95, 96 and 97 are computed using the equations 2, 5, 10 and 11 respectively.
