get_meteo function

Get daily, monthly, or annual; aggregated or long-term means meteorological data for specific location(s) and date(s).

The function gives back daily, monthly, or annual and aggregated or long-term means metorological data for specific location(s) and date(s) for entire World for 1961-2020 period from DailyMeteo portal (https://app.dailymeteo.com/).

get_meteo(loc,
          var = "tmean",
          agg_level = "agg",
          time_scale = "day",
          time,
          from,
          to,
          api_key)

Arguments

• loc: sf, SpatVector, data.frame , matrix, numeric or integer; Location(s) in WGS84 (EPSG:4326). If data.frame or matrix columns are lon/lat. See get_coordinates.
• var: character; Meteorological variable. Possible values are: "tmean" (mean temperature, default), "tmax" (maximum temperature), "tmin" (minimum temperature), "prcp" (total precipitation), or "slp" (sea-level pressure).
• agg_level: character; Aggregation level. Possible values are: "agg" (aggregated, default) or "ltm" (long-term mean).
• time_scale: character; Time scale. Possible values are: "day" (daily, default), "mon" (monthly), or "ann" (annual).
• time: character; Vector of time references. If specified, ignore from and to. If time_scale="day" then format is 'YYYY-MM-DD'. If time_scale="mon" then the format is 'YYYY-MM'. If time_scale="ann" then format is 'YYYY' (e.g. if time_scale="day" then c('2020-01-01,2020-01-02'); if time_scale="mon" then c('2020-01,2020-02'); if time_scale="ann" then c('2020,2019')).
• from: character; Time reference from. Format is the same as for the parameter time
• to: character; Time reference to. Format is the same as for the parameter time
• api_key: character; API key. Check DailyMeteo portal (https://app.dailymeteo.com/)

Returns

data.frame object with columns loc (location index from loc argument), timestamp (time reference), and value (meteorological value).
