meteospain (version 0.3.0)

get_meteo_from: Get meteorological stations data

Description

Connect and retrieve data from AEMET, SMC and other Spanish meteorological stations services.

Usage

get_meteo_from(
  service = c("aemet", "meteocat", "meteoclimatic", "meteogalicia", "ria"),
  options
)

Value

An sf (spatial) object with the stations meteorological data.

Arguments

service

Character with the service name (in lower case).

options

List with the needed service options. See services_options to have more info about the different services and their options.

API limits

Some APIs have limits in terms of the data that can be retrieved with one call. For example, AEMET only serves daily data for 31 days in one query. See vignette('api_limits', package = 'meteospain') for a detailed explanations of those limits and the ways to retrieve longer periods.

Cache

To avoid unnecessary API calls (especially in rate-limited APIs), results are cached to memory in a cache_mem object. This cache is limited to the actual R session and invalidates after 24h. Temporal resolutions below daily are not cached, as they change often.

This cache can be cleared with clear_meteospain_cache.

Details

Depending on the service and the temporal resolution selected, the variables present can change, but all services have at least temperature values.

Examples

if (FALSE) { # interactive()
  library(meteospain)
  library(keyring)

  # AEMET (we need a key)
  # key_set('aemet')
  options_for_aemet <- aemet_options(
    'daily',
    start_date = as.Date('2012-01-16'),
    end_date = as.Date('2012-01-31'),
    api_key = key_get('aemet')
  )
  get_meteo_from('aemet', options_for_aemet)
}
