ncdc_stations: Get metadata about NOAA NCDC stations.

Description

From the NOAA NCDC API docs: Stations are where the data comes from (for most datasets) and can be considered the smallest granual of location data. If you know what station you want, you can quickly get all manner of data from it

Usage

ncdc_stations(stationid = NULL, datasetid = NULL, datatypeid = NULL,
  locationid = NULL, startdate = NULL, enddate = NULL, sortfield = NULL,
  sortorder = NULL, limit = 25, offset = NULL, datacategoryid = NULL,
  extent = NULL, token = NULL, dataset = NULL, station = NULL,
  location = NULL, locationtype = NULL, page = NULL, ...)

Arguments

stationid

Accepts a valid station id or a chain of of station ids in a comma-separated vector. Data returned will contain data for the station(s) specified (optional)

datasetid

(optional) Accepts a single valid dataset id. Data returned will be from the dataset specified, see datasets()

datatypeid

Accepts a valid data type id or a chain of data type ids in a comma-separated vector. Data returned will contain all of the data type(s) specified (optional)

locationid

Accepts a valid location id or a chain of location ids in a comma-separated vector. Data returned will contain data for the location(s) specified (optional)

startdate

(optional) Accepts valid ISO formated date (yyyy-mm-dd) or date time (YYYY-MM-DDThh:mm:ss). Data returned will have data after the specified date. The date range must be less than 1 year.

enddate

(optional) Accepts valid ISO formated date (yyyy-mm-dd) or date time (YYYY-MM-DDThh:mm:ss). Data returned will have data before the specified date. The date range must be less than 1 year.

sortfield

The field to sort results by. Supports id, name, mindate, maxdate, and datacoverage fields (optional)

sortorder

Which order to sort by, asc or desc. Defaults to asc (optional)

limit

Defaults to 25, limits the number of results in the response. Maximum is 1000 (optional)

offset

Defaults to 0, used to offset the resultlist (optional)

datacategoryid

(character, optional) Accepts a valid data category id or an array of data category ids. Stations returned will be associated with the data category(ies) specified

extent

(numeric, optional) The geographical extent for which you want to search. Give four values that defines a bounding box, lat and long for the southwest corner, then lat and long for the northeast corner. For example: c(minlat, minlong, maxlat, maxlong).

token

This must be a valid token token supplied to you by NCDC's Climate Data Online access token generator. (required) Get an API key (=token) at http://www.ncdc.noaa.gov/cdo-web/token. You can pass your token in as an argument or store it in your .Rprofile file with an entry like

• options("noaakey" = "your-noaa-token")

dataset

THIS IS A DEPRECATED ARGUMENT. See datasetid.

station

THIS IS A DEPRECATED ARGUMENT. See stationid.

location

THIS IS A DEPRECATED ARGUMENT. See locationid.

locationtype

THIS IS A DEPRECATED ARGUMENT. There is no equivalent argument in v2 of the NOAA API.

page

THIS IS A DEPRECATED ARGUMENT. There is no equivalent argument in v2 of the NOAA API.

Curl options passed on to GET (optional)

Value

A list of metadata.
