Name Cardinality Type Description

Name	Cardinality	Type	Description
`errorEllipseMinorSemiAxis`	1	`Length`	Length of minor semi-axis (shortest radius) of the error ellipse.
`errorEllipseConfidence`	0..1	`PerCent`	Likelihood that strike fell within errorEllipse.
`errorEllipseMajorSemiAxis`	0..1	`Length`	Length of major semi-axis (longest radius) of the error ellipse.
`errorEllipseOrientation`	0..1	`Bearing`	The orientation of the major semi- axis in degrees from True North.
`negativePolarity`	0..1	`boolean`	The polarity of the strike, with T meaning negative. About 90% of all lightning strokes are negative strokes, meaning that they were initiated by a large concentration of negative charge in the cloud-base; this tends to induce an area of positive charge on the ground.
`peakAmplitude`	0..1	`CurrentFlow`	Peak current of strike.
`EnvironmentalInformation`	0..1	`EnvironmentalInformation`	The forecast or observation of which this phenomenon description is a part.
`PhenomenonClassification`	0..1	`PhenomenonClassification`	The classification of this phenomenon.
`timeInterval`	0..1	`DateTimeInterval`	The timestamp of the phenomenon as a single point or time interval.
`EnvironmentalLocationKind`	0..*	`EnvironmentalLocationType`	Location of relevance to this environmental phenomenon.
