Historical Observing Metadata Repository (HOMR) station metadata

Description

Historical Observing Metadata Repository (HOMR) station metadata

Usage

homr(
  qid = NULL,
  qidMod = NULL,
  station = NULL,
  state = NULL,
  county = NULL,
  country = NULL,
  name = NULL,
  nameMod = NULL,
  platform = NULL,
  date = NULL,
  begindate = NULL,
  enddate = NULL,
  headersOnly = FALSE,
  phrData = NULL,
  combine = FALSE,
  ...
)

Arguments

qid	One of COOP, FAA, GHCND, ICAO, NCDCSTNID, NWSLI, TRANS, WBAN, or WMO, or any of those plus a-z0-9, or just a-z0-9. (qid = qualified ID)
qidMod	(character) One of: is, starts, ends, contains. Specifies how the ID portion of the qid parameter should be applied within the search. If a qid is passed but the qidMod parameter is not used, qidMod is assumed to be IS.
station	(character) A station id.
state	(character) A two-letter state abbreviation. Two-letter code for US states, Canadian provinces, and other Island areas.
county	(character) A two letter county code. US county names, best used with a state identifier.
country	(character) A two letter country code. See here for a list of valid country names.
name	(character) One of ⁠0-9A-Z+⁠. Searches on any type of name we have for the station.
nameMod	(character) is|starts|ends|contains. Specifies how the name parameter should be applied within the search. If a name is passed but the nameMod parameter is not used, nameMod is assumed to be IS.
platform	(character) (aka network) ⁠ASOS|USCRN|USHCN|NEXRAD|AL USRCRN|USRCRN|COOP⁠. Limit the search to stations of a certain platform/network type.
date	(character) YYYY-MM-DD|all Limits values to only those that occurred on a specific date. Alternatively, date=all will return all values for matched stations. If this field is omitted, the search will return only the most recent values for each field.
begindate, enddate	YYYY-MM-DD. Limits values to only those that occurred within a date range.
headersOnly	(logical) Returns only minimal information for each station found (NCDC Station ID, Preferred Name, Station Begin Date, and Station End Date), but is much quicker than a full query. If you are performing a search that returns a large number of stations and intend to choose only one from that list to examine in detail, headersOnly may give you enough information to find the NCDC Station ID for the station that you actually want.
phrData	(logical) The HOMR web service now includes PHR (element-level) data when available, in an elements section. Because of how this data is structured, it can substantially increase the size of any result which includes it. If you don't need this data you can omit it by including phrData=false. If the parameter is not set, it will default to phrData=true.
combine	(logical) Combine station metadata or not.
...	Curl options passed on to crul::verb-GET (optional)

Details

Since the definitions for variables are always the same, we don't include the ability to get description data in this function. Use homr_definitions() to get descriptions information.

Value

A list, with elements named by the station ids.
