ncdc_locs: Get metadata about NOAA NCDC locations.

Description

From the NOAA NCDC API docs: Locations can be a specific latitude/longitude point such as a station, or a label representing a bounding area such as a city.

Usage

ncdc_locs(
  datasetid = NULL,
  locationid = NULL,
  locationcategoryid = NULL,
  startdate = NULL,
  enddate = NULL,
  sortfield = NULL,
  sortorder = NULL,
  limit = 25,
  offset = NULL,
  token = NULL,
  ...
)

Value

A list containing metadata and the data, or a single data.frame.

Arguments

datasetid

A valid dataset id or a vector or list of dataset id's. Data returned will be from the dataset specified, see datasets() (required)

locationid

A valid location id or a vector or list of location ids.

locationcategoryid

A valid location id or a vector or list of location category ids

startdate

A valid ISO formatted date (yyyy-mm-dd). Data returned will have data after the specified date. Paramater can be use independently of enddate (optional)

enddate

Accepts valid ISO formatted date (yyyy-mm-dd). Data returned will have data before the specified date. Paramater can be use independently of startdate (optional)

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.

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

Examples

if (FALSE) {
# All locations, first 25 results
ncdc_locs()

# Fetch more information about location id FIPS:37
ncdc_locs(locationid='FIPS:37')

# Fetch available locations for the GHCND (Daily Summaries) dataset
ncdc_locs(datasetid='GHCND')
ncdc_locs(datasetid=c('GHCND', 'ANNUAL'))
ncdc_locs(datasetid=c('GSOY', 'ANNUAL'))
ncdc_locs(datasetid=c('GHCND', 'GSOM'))

# Fetch all U.S. States
ncdc_locs(locationcategoryid='ST', limit=52)

# Many locationcategoryid's
## this apparently works, but returns nothing often with multiple
## locationcategoryid's
ncdc_locs(locationcategoryid=c('ST', 'ZIP'))

# Fetch list of city locations in descending order
ncdc_locs(locationcategoryid='CITY', sortfield='name', sortorder='desc')
