Downloading hourly or daily (meteorological) data from the Synop stations available at https://www.ogimet.com/
'daily' or 'hourly' dataset to retrieve - given as character
start and finish date (e.g., date = c("2018-05-01", "2018-07-01")) - character or Date class object. If not provided last 30 days are used.
add geographical coordinates of the station (logical value TRUE or FALSE)
WMO ID of meteorological station(s). Character or numeric vector
whether to split precipitation fields into 6/12/24h
logical - whether to proceed or stop on failure. By default set to TRUE (i.e. don't stop on error). For debugging purposes change to FALSE numeric fields (logical value TRUE (default) or FALSE); valid only for hourly time step
A data.frame of measured values with columns describing the meteorological parameters (e.g. air temperature, wind speed, cloudines). Depending on the interval, at a given hour or day. Different parameters are returned for daily and hourly datasets.
