select.station: Select from meta data base

In metno/esd: Climate analysis and empirical-statistical downscaling (ESD) package for monthly and daily data

Select from meta data base

Description

Function that searches the meta data base for the requested station data Search priority: ID, name, coordinates, altitude, country,... Can return several matches

Usage

select.station(
  x = NULL,
  ...,
  loc = NULL,
  param = NULL,
  ele = NULL,
  stid = NULL,
  lon = NULL,
  lat = NULL,
  alt = NULL,
  cntr = NULL,
  src = NULL,
  it = NULL,
  nmin = NULL,
  user = "external",
  update.meta = FALSE,
  verbose = FALSE
)

Arguments

loc	A string of characters as the name of the location (weather/climate station) or an object of class "stationmeta".
param	Parameter or element type or variable identifier. There are several core parameters or elements as well as a number of additional parameters. The parameters or elements are: precip = Precipitation (mm) tas, tavg = 2m-surface temperature (in degrees Celcius) tmax, tasmax = Maximum temperature (in degrees Celcius) tmin, tasmin = Minimum temperature (in degrees Celcius)
stid	A string of characters as an identifier of the weather/climate station.
lon	Numeric value of longitude (in decimal degrees East) for the reference point (e.g. weather station) as a single value or a vector containing the range of longitude values in the form of c(lon.min,lon.max)
lat	Numeric value of latitude for the reference point (in decimal degrees North) or a vector containing the range of latitude values in the form of c(lat.min,lat.max)
alt	Numeric value of altitude (in meters a.s.l.) used for selection. Positive value, select all stations above this altitude; for negative values, select all stations below this latitude.
cntr	A string or a vector of strings of the full name of the country: Select the stations from a specified country or a set of countries.
src	Source: limit the downscaling to a specific data set ("NARP", "NACD", "NORDKLIMA", "GHCNM", "METNOM", "ECAD", "GHCND" and "METNOD")
it	A single integer or a vector of integers or Dates. An integer in the range of [1:12] for months, an integer of 4 digits for years (e.g. 2014), or a vector of Dates in the form "2014-01-01").
nmin	Select only stations with at least nmin number of years, months or days depending on the class of object x (e.g. 30 years).
verbose	Logical value defaulting to FALSE. If FALSE, do not display comments (silent mode). If TRUE, displays extra information on progress.

Value

A data.frame holding meta data about available station data.
