meteostat

D = meteostat()

Download the Meteostat stations list and return it as a GMTdataset.

[D =] meteostat(lon::Real, lat::Real, [granularity::Dates.Period,] [startdate::Date,] [enddate::Date,] verbose::Bool=true)

Retrieve weather data, obtained from the Meteostat, for the station that is closest to the given coordinates.

Args

• lon: Longitude of the location.

• lat: Latitude of the location.

• granularity: The granularity of the data. It can be either Day or Hour (from the Dates module), where Day means one value per day and Hour means one value per hour. Day is the default.

• startdate: The start date of the data to extract. If not provided, it defaults to the first day of the current year for Hour granularity or an old year (1900), such that the entire time series is downloaded, for Day granularity.

• enddate: The end date of the data to extract. If not provided, it defaults to today.

• verbose: If true, print download/load file information.

The files are downloaded from the Meteostat endpoint and saved in a cache folder in the tmp directory. Later reuse reads from the cache folder when files are not older than a day to ensure that the most updated data is used.

Returns

A GMTdataset with the data from the closest station to the given coordinates.

Example

Download data from the stations that are closest to the given coordinates.

using GMT
D = meteostat(-8.0, 37.0, Date(2023), Date(2024))
viz(D)

D = meteostat(ID::String, [granularity::Dates.Period,] [startdate::Date,] [enddate::Date,] verbose::Bool=true) -> GMTdataset

Same as above but using a station ID or Name instead of a location specified by coordinates. ID can be the 5 characters station ID or a part of the station Name (see the meteostat() function). The second form is less reliable since partial names (case sensitive) may match multiple stations.

Example

Plot 2018 temperature data for Vancouver, BC.

using GMT
D = meteostat("Vancouver", Date(2018,1,1), Date(2018,12,31));
viz(D, title="Temperature in Vancouver, BC")
