#### Description

The International Best Track Archive for Climate Stewardship (IBTrACS)
provides location and intensity for global tropical cyclones. The data span
from the 1840s to present, generally providing data at 3-hour intervals.
While the best track data is focused on position and intensity
(maximum sustained wind speed or minimum central pressure), other parameters
are provided by some agencies (e.g., radius of maximum winds, environmental
pressure, radius of hurricane force winds, etc.) and are likewise provided
in IBTrACS. Files are available subset by Basin or time period, where basins
include: East Pacific, North Atlantic, North Indian, South Atlantic,
South Indian, South Pacific, and the West Pacific.

### Table Schema

**Table Schema**
Name Type Description SID STRING Storm Identifier
SEASON DOUBLE Year in which the storm occurred
NUMBER DOUBLE The cardinal number of the system for that season.
The count includes all basins, so this will not be continuous for
basin files.
BASIN STRING Basins include:

- NA: North Atlantic
- EP: Eastern North Pacific
- WP: Western North Pacific
- NI: North Indian
- SI: South Indian
- SP: Southern Pacific

Most points are provided at 6 hour intervals.
Some agencies provided 3 hour points (e.g., New Delhi) or times at
important observations (e.g.,landfall times in the North Atlantic,etc)
NATURE STRING Combined storm type.
This is assigned based on all available storm types.
Values:

- DS: Disturbance
- TS: Tropical
- ET: Extratropical
- SS: Subtropical
- NR: Not reported
- MX: Mixture (contradicting nature reports from different agencies)
WMO_WIND DOUBLE Maximum sustained wind speed from the WMO agency for the current
location.
NO adjustment is made for differences in wind speed averaging periods.
hurdat/atcf = North Atlantic - U.S. Miami (NOAA NHC) - 1-minute winds
tokyo = RSMC Tokyo (JMA) - 10-minute
newdelhi = RSMC New Delhi (IMD) - 3-minute

WMO_PRES DOUBLE Minimum central pressure assigned by the responsible WMO agnecy
WMO_AGENCY STRING This is the reporting agency responsible for the basin as currently
listed.It should be noted that many of the agencies did not accept
official WMO responsibility until relatively recently,
e.g., La Reunion in 1993 or IMD in 1990. Therefore the WMO agency is
used loosely to describe the currently responsible agency.
TRACK_TYPE STRING Track type
Tropical storms can interact.
Values:

- PROVISIONAL: Real time data used to populate the position and other parameters of this system.This is a provisional track that will be replaced when reanalysis of the storm is performed. (Usually within 2 years of the storm's occurrence)
- PROVISIONAL_spur: Real time data (see provisional description above) but due to differences in positions between various inputs, algorithm can not identify accurate position. When counting storms, these should not likely be counted. These should be rare for PROVISIONAL data.
- MAIN: primary track associated with a storm system. This is a track that has had some reanalysis and is higher quality than provisional data.
- spur: usually short lived tracks associated with a main track and often represents alternate positions at the beginning of a system. Can also represent actual system interactions (e.g., Fujiwhara interactions).
DIST2LAND DOUBLE Distance to land from the current position.
The land dataset includes all continents and any islands larger than
1400 km\^2. The distance is the nearest at the present time in any
direction.
LANDFALL DOUBLE Nearest location to land within next 6 hours.
This can be thought of a landfall flag:
=0 -- Landfall within 6 hours.
> 0 -- No landfall within next 6 hours.
> Calculations are based on storm center (columns 9,10).
> Values less than 60 nmile likely are impacted by the system even
> though the center of the system is not over land.
> The uses the same land mask as DIST2LAND.
