ncdc_stations: Get metadata about NOAA NCDC stations.

In rnoaa: 'NOAA' Weather Data from R

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	A single valid station id, with datasetid namespace, e.g., GHCND:USW00014895
datasetid	(optional) Accepts a valid dataset id or a vector or list of them. Data returned will be from the dataset specified.
datatypeid	Accepts a valid data type id or a vector or list of data type ids. (optional)
locationid	Accepts a valid location id or a vector or list of location ids (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 a vector or list of data category ids.
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) See Authentication section below for more details.
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 HttpClient (optional)

Value

A list of metadata.

Authentication

Get an API key (aka, token) at https://www.ncdc.noaa.gov/cdo-web/token You can pass your token in as an argument or store it one of two places:

• your .Rprofile file with the entry options(noaakey = "your-noaa-token")

• your .Renviron file with the entry NOAA_KEY=your-noaa-token

See Startup for information on how to create/find your .Rrofile and .Renviron files
