fmi_weather: fmi_weather

In paasim/simplefmi: An R package for FMI weather data

fmi_weather

Description

Download data from the fmi weather API. If the request is larger than the api allows, it is split into multiple parts. If this results to more than 30 queries, a warning message is printed.

Usage

fmi_weather(
  start,
  end = start,
  station_id = "100971",
  params = ifelse(hourly, "t2m,r_1h", "tday,rrday"),
  hourly = FALSE,
  simplify_names = TRUE,
  verbose = FALSE,
  fmi_apikey = NA_character_
)

Arguments

start	Start time as a POSIXt-object obtained with e.g. lubridate::as_datetime().
end	End time as a POSIXt-object. Defaults to start.
station_id	The weather station id. Defaults to 100971. (Kaisaniemi weather station). A list of the available stations can be downloaded with the get_stations()-function.
params	Query parameters, a comma separated string, such as "tday,rrday". For more options, see Details.
hourly	If TRUE, hourly data is downloaded. Otherwise the daily data is downloaded.
simplify_names	If TRUE, variable names are simplified (eg. t2m is converted to temp).
verbose	If TRUE, prints the progress. Defaults to FALSE.
fmi_apikey	An optional fmi-apikey. See http://en.ilmatieteenlaitos.fi/open-data-manual.
