Endpoint: tropicalcyclones/archive

The tropical cyclones archive endpoint provides access to archive information for global tropical cyclones, including tropical storms, hurricanes, and typhoons.  Includes information on an individual storms name, historical track and if active, position and forecast information. The tropical archive information is based on data from the National Hurricane Center (NHC), Central Pacific Hurricane Center (CPHC), and the Joint Typhoon Warning Center (JTWC). Archive information is available from 1851 for the Atlantic basin and the 1940s for the Pacific basins.

Supported Actions

The following actions are supported with the tropicalcyclones/archive endpoint:

:id Requesting data by using the :id action is used for returning data for a particular item that has an ID associated with it. This is the primary method for requesting general weather information for a single location (observations, forecasts, advisories, etc.) as the location's name or a zip code serves as the id. Other endpoints may expect a certain value for the ID, such as storm cells whose ID value is a combination of the radar site identifier and unique identifier assigned to every storm cell. Refer to an enpoint's detailed documentation for specific information regarding how to use the :id action.
closest The closest action will query the API for data that is closest to the requested place and return the results, if any, in order from closest to farthest. If no limit is provided in the request, then only the closest single result will be returned.

If your request does not return results, you may try setting or increasing the radius being used.
search The search action is used as a more general query method and expects the query to be defined with the custom query for the request. Unlike the closest action, results will not be returned in any particular order.
within The within action allows for returning data within a variety of different geometrical regions. Currently supported geometries include a circle (requires a center point and radius), square (requires two coordinate points defining the top-left and bottom-right corners) and polygon (requires at least three coordinate points). Unlike the closest action, the results will not be returned in any particular order based on distance.
affects The affects action requests all places affected by a particular type of event, such as earthquake or storm cell. The query for places affected is unique for each endpoint it belongs to and can be a polygon (e.g., storm cell forecasts or warnings) or a circle with the center being the location of the event (e.g., earthquakes or fires). Instead of returning an array of objects specific to the endpoint, the affects action will always return an array of place objects in the same format as the within action on the places endpoint.

Note: Not all endpoints support this action, so refer to each endpoint's complete documentation to determine if supported and its usage.

Supported Parameters

The following parameters are optional unless otherwise noted:

p p=:place Defines the location to query data for. Refer to the list of supported place value formats.
fields fields=:string Provides a comma separated list of values for the API to return. This parameter is often used to limit the amount of data returned. See Reducing Output.
filter filter=:string Predefined filters for limiting the results. The filter value can be a single, comma-delimited or a semicolon delimited string of filter names.
format format=:string Defines the API output format. The available options include:
format=json - Standard JSON output. This is the default.
format=geojson - API will output GeoJSON.

If obtaining GeoJSON and using the fields parameter, be sure to include loc to ensure geographical references are available in the response.
from from=:string Returns the results starting form the value specified. For best practices we recommend using the to parameter as well to define a specific time frame.

Supports a UNIX timestamp or a specific date string. Alternatively, common date formats supported by the PHP strtotime() function will be accepted; however, commas are not accepted.

Examples:
from=tomorrow
from=friday
from=1302883980
from=7/10/2011
from=2011/07/10
from=+2hours
from=2017-02-27 5:00 PM
limit limit=:total The total number of results to return as an integer. Each endpoint may have a set maximum for this value depending on usage.

The default limit is 1 if not specified.
query query=:string Used to filter results based on certain fields in the data set. See Advanced Queries for more details.
radius radius=:distance:unit When requesting the closest results within a circle, the radius determines how far from the specified location to search. A valid unit value must be included in your radius value, e.g., "5mi", "10km", "25miles". If no unit is provided, your value is assumed to be in meters by default.

Most endpoints utilize a default radius of 50 miles, though some endpoints, such as lightning, may have tighter restrictions specified.
skip skip=:number Used to skip over a specific number of results in the data set.
sort sort=:string Used to sort results based on certain fields in the data set. See Sorting for more details.
to to=:string Returns the results between now and the value specified. For best practices we recommend using the from parameter as well to define a specific time frame. When used in conjunction with the from parameter, the value of to will be relative to the value of from, not relative to the current time.

Supports a UNIX timestamp or a specific date string. Alternatively, common date formats supported by the PHP strtotime() function will be accepted; however, commas are not accepted.

Examples:
to=+6hours
to=+5days
to=1302883980
to=7/10/2011
to=2011/07/10
to=2017-02-27 5:00 PM
callback callback=:functionName Used with JSONP implementation.

Defines the callback function to use for the response. The response will be enclosed as C(response), where C is the callback function provided.

Supported Filters

The following filters can be passed to the filter parameter to reduce the results that are returned:

active Return information on active systems (Default)
notactive Return information on non active systems
atlantic Return tropical systems within the Atlantic basin
al Alias for atlantic
eastpacific Return tropical systems within the Eastern Pacific basin
ep Alias for eastpacific
centralpacific Return tropical systems within the Central Pacific basin
cp Alias for centralpacific
westpacific Return tropical systems within the Western Pacific basin
wp Alias for westpacific
pacific Return tropical systems within the Eastern, Central and Western Pacific basins
indian Return tropical systems within the Indian Ocean basin
io Alias for indianocean
southern Return tropical systems within the Southern Hemisphere basin
sh Alias for southernhemisphere
position Used when searching by location, closest and within actions. Search based on system current position (This is the default behavior)
track Used when searching by location, closest and within actions. Search based on system historical track
forecast Used when searching by location, closest and within actions. Search based on system forecast track
geo Used to force the API to return the error cone when available. By default the API does not return the error cone due to the large amount of data.
test Return Test storm information, useful for development and demonstration
