ncdc_datasets: Search NOAA datasets

Description

From the NOAA API docs: All of our data are in datasets. To retrieve any data from us, you must know what dataset it is in.

Usage

ncdc_datasets(datasetid = NULL, datatypeid = NULL, stationid = NULL,
  locationid = NULL, startdate = NULL, enddate = NULL,
  sortfield = NULL, sortorder = NULL, limit = 25, offset = NULL,
  token = NULL, dataset = NULL, page = NULL, year = NULL,
  month = NULL, ...)

Arguments

datasetid

(optional) Accepts a single valid dataset id. 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)

stationid

Accepts a valid station id or a vector or list of station ids

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)

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.

page

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

year

THIS IS A DEPRECATED ARGUMENT. Use combination of startdate and enddate arguments.

month

THIS IS A DEPRECATED ARGUMENT. Use combination of startdate and enddate arguments.

...

Curl options passed on to HttpClient (optional)

Value

A data.frame for all datasets, or a list of length two, each with a data.frame.

Authentication

Get an API key (aka, token) at http://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 an entry like options(noaakey = "your-noaa-token")

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

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