The actual or forecast characteristics of an environmental phenomenon at a specific point in time (or during a specific time interval) that may have both a center and area/line location.
A hydrospheric phenomenon.
No Additional PropertiesTsunami magnitude in the Tsunami Magnitude Scale (Mt). Is greater than zero.
The timestamp of the phenomenon as a single point or time interval.
End date and time of this interval. The end date and time where the interval is defined up to, but excluded.
Start date and time of this interval. The start date and time is included in the defined interval.
Tsunami intensity on the Papadopoulos-Imamura tsunami intensity scale. Possible values are 1-12, corresponding to I-XII.
An atmospheric phenomenon with a base and altitude providing the vertical coverage (combined with the Location to provide three dimensional space).
No Additional PropertiesThe type of the cloud as defined by the CloudKind enumeration.
Particulate density of the ash cloud during the time interval.
nan
nan
nan
The diameter of the particles during the time interval.
nan
Wind Force as classified on the Beaufort Scale (0-12) during the time interval.
The maximum percentage coverage
Normally 0 to 100 on a defined base.
The central pressure of the cyclone during the time interval.
nan
Fujita scale (referred to as EF-scale starting in 2007) for the tornado.
Strength of tropical cyclone during the time interval, based on Australian Bureau of Meteorology Category System where:
1 - tropical cyclone, with typical gusts over flat land 90-125 km/h
2 - tropical cyclone, with typical gusts over flat land 125-164 km/h
3 - severe tropical cyclone, with typical gusts over flat land 165-224 km/h
4 - severe tropical cyclone, with typical gusts over flat land 225-279 km/h
5 - severe tropical cyclone, with typical gusts over flat land greater than 280 km/h.
The timestamp of the phenomenon as a single point or time interval.
Same definition as EnvironmentalPhenomenon.timeIntervalThe base altitude of the phenomenon.
nan
nan
nan
Width of the tornado during the time interval.
Same definition as VolcanicAshCloud.particleSizeThe direction the phenomenon is moving.
nan
The maximum surface wind speed of the cyclone during the time interval.
nan
The minimum percentage coverage
Same definition as AtmosphericPhenomenon.maxCoverageThe hurricane's category during the time interval, using Saffir-Simpson Hurricane Wind Scale, a 1 to 5 rating based on a hurricane's sustained wind speed.
A geospheric phenomenon.
No Additional PropertiesLikelihood that strike fell within errorEllipse.
Same definition as AtmosphericPhenomenon.maxCoverageThe 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.
The intensity of the earthquake as defined by the Modified Mercalli Intensity (MMI) scale. Possible values are 1-12, corresponding to I-XII.
Length of major semi-axis (longest radius) of the error ellipse.
Same definition as VolcanicAshCloud.particleSizeThe timestamp of the phenomenon as a single point or time interval.
Same definition as EnvironmentalPhenomenon.timeIntervalPeak current of strike.
nan
The depth below the earth's surface of the earthquake's focal point.
Same definition as AtmosphericPhenomenon.baseThe orientation of the major semi- axis in degrees from True North.
Same definition as AtmosphericPhenomenon.directionLength of minor semi-axis (shortest radius) of the error ellipse.
Same definition as VolcanicAshCloud.particleSizeThe magnitude of the earthquake as defined on the Moment Magnitude (Mw) scale, which measures the size of earthquakes in terms of the energy released. Must be greater than zero.
An extra-terrestrial phenomenon.
No Additional PropertiesChange in the disturbance - storm time (Dst) index. The size of a geomagnetic storm is classified as:
- moderate ( -50 nT >minimum of Dst > -100 nT)
- intense (-100 nT > minimum Dst > -250 nT) or
- super-storm ( minimum of Dst < -250 nT).
nan
The timestamp of the phenomenon as a single point or time interval.
