get_Solardata: get_Solardata

In AlbyDR/rSCOPE: Run SCOPE model through R

get_Solardata

Description

This is a function to download DWD data based on a buffer distance. The meteorological variables are provide in data.frame per station id.

Usage

get_Solardata(
  lat_center,
  lon_center,
  radius_km,
  time_lag = "hourly",
  meteo_var = "solar",
  start_date,
  end_date,
  data_dir = tempdir()
)

Arguments

lat_center	latitude central point for the buffer
lon_center	longitude central point for the buffer
radius_km	for the buffer
time_lag	default "hourly" , it can be change for daily or other timestamp available
meteo_var	type of meteorological data target in the DWD ftp (see option below)
start_date	select stations with date later than
end_date	select stations with date earlier than
data_dir	where to save the downlaod data, default temporary.
period	default "historical", if change to "recent" you get one year lag up to "now".
var_name	variable name target in the the downloaded meteo_var file (see option below)

Value

a list with: 1- a data.frame with the selected variable per station id for the set timestamp, and 2- a data.frame with metadata information, such as stations_id, start_date, end_date, station_height, latitude, longitude, stations_name, region, time_lag, variable, period, file, distance, url.
