)

Arguments

keyfile	The path where the frost.met.no credentials keyfile is stored locally.
url	The URL of the data portal or webpage for requesting new client credentials.
stid	A string of characters as an identifier of the weather/climate station.
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)
it	A vector of two dates (from and to) in the form "2014-01-01".
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)
loc	A string of characters as the name of the location (weather/climate station) or an object of class "stationmeta".
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.
timeresolutions	A string of the desired time resolution. Accepted strings are the ISO 8601 durations P1M, P1D and PT1M, as well as the strings MONTHLY, MONTH, DAILY, DAY, MINUTE and MIN. If no value is set, this defaults to P1M.
levels	Numeric value of sensor height used for selection. If no value is set, then standard heights will be selected.
timeoffsets	A string of the ISO 8601 duration desired for the offset value of timeseries. If no value is set, then the best available option will be selected.
performancecategories	A string with a comma-separated list of categories to accept for sensor performance. If no value is set, then the default A,B,C will be used.
exposurecategories	A string with a comma-separated list of categories to accept for siting quality of the sensor. If no value is set, then the default 1,2 will be used.
qualities	A string with a comma-separated list of quality codes to accept for the individual measurements. If no value is set, then the default 0,1,2,3,4,5 will be used.
fetch.meta	Logical value defaulting to TRUE. If TRUE, download timeseries metadata from frost.met.no. If FALSE, try to load data file station.meta instead.
path	The path where the data are stored. Can be a symbolic link.
browser	A string signifying which internet browser to open to ask user to create new credentials for frost.met.no
save2file	Logical value defaulting to FALSE. If TRUE, save a file with the output data.
verbose	Logical value defaulting to FALSE. If FALSE, do not display comments (silent mode). If TRUE, displays extra information on progress.
...	additional arguments

Value

A time series of "zoo" "station" class with additional attributes used for further processing.
