Reads a file from the SwissMetNet of MeteoSwiss

Description

SwissMetNet, the automatic monitoring network of MeteoSwiss the Federal Office for Meteorology and Climatology, comprises about 160 automatic monitoring stations. These stations deliver a multitude of current data on the weather and climate in Switzerland every ten minutes. The monitoring network is supplemented by automatic precipitation stations.

This Function autodetects the delimeter and tries to find the interval. In Addition the time information in the files is utc and end time. The time is converted to start time and the time zone defined trough the argument tz. The argument time_shift provides a way to manuelly shift the time series. In this case no automatically shifting is applied. The provided values is directly added to information in the file.

Usage

read_smn(
  fn,
  tz = "Etc/GMT-1",
  encoding = "UTF-8",
  time_shift = NULL,
  time_format = NULL,
  interval = NULL,
  na.rm = TRUE
)

Arguments

fn	path to input file
tz	of the output data. Default "Etc/GMT-1"
encoding	encoding of the data file. Default = "UTF-8"
time_shift	a lubridate period to add to the time. Default NULL
time_format	optional time_format. Use if auto detect fails. Default NULL
interval	optional interval of the data. Use if auto detect fails. Default NULL. If used it is necessary to define time_shift manuelly. lubridate::period(0) can be used for no shifting
na.rm	remove na values. Default TRUE

Value

tibble in rOstluft long format structure

Examples

input <- system.file("extdata", "smn.txt", package = "rOstluft.data", mustWork = TRUE)
