Collection Snippet
ee.FeatureCollection("NOAA/NHC/HURDAT2/atlantic")
Name | Type | Description |
seq | Double | ATCF cyclone number for that year |
name | String | Hurricane name. e.g. "ALEX" |
datetime | String | Observation time in UTC. Format is YYYY-MM-DDTHH:MM:SS. |
record_id | String | Single letter desinating a specific event in a hurricane track. An empty string if no code. - C – Closest approach to a coast not followed by a landfall - G – Genesis - I – An intensity peak in terms of both pressure and wind - L – Landfall (center of system crossing a coastline) - P – Minimum in central pressure - R – Provides additional detail on the intensity of the cyclone when rapid changes are underway - S – Change of status of the system - T – Provides additional detail on the track (position) of the cyclone - W – Maximum sustained wind speed |
status | String | Status of system: - DB – Disturbance (of any intensity) - ET - Unknown. The only occurrence is in HARVEY. - EX – Extratropical cyclone (of any intensity) - HU – Tropical cyclone of hurricane intensity (> 64 knots) - LO – A low that is neither a tropical cyclone, a subtropical cyclone, nor an extratropical cyclone (of any intensity) - SD – Subtropical cyclone of subtropical depression intensity (< 34 knots) - SS – Subtropical cyclone of subtropical storm intensity (> 34 knots) - TD – Tropical cyclone of tropical depression intensity (< 34 knots) - TS – Tropical cyclone of tropical storm intensity (34-63 knots) - WV – Tropical Wave (of any intensity) |

basin | String | Ocean basin. Always "AL" for Atlantic. |
id | String | Code for a particular hurricane. "AL" followed by a 2 digit cyclone number followed by a 4-digit year. e.g. "AL162018" |
year | Double | Year in which the hurricane occurred |
