DEPRECATED. Download data from the Catalan automatic weather station network (XEMA from Servei Meteorològic de Catalunya)

downloadSMCstationlist(api, date = NULL)
downloadSMCcurrentday(api, daily = TRUE,
                      station_id=NULL, date = Sys.Date(), verbose=TRUE)
downloadSMChistorical(api, date, station_id=NULL, export = FALSE, 
                      exportDir = getwd(), exportFormat = "meteoland/txt",
                      metadataFile = "MP.txt", verbose=TRUE)

Arguments

api

String with the SMC API key (the procedure to apply for an api key is explained in https://apidocs.meteocat.gencat.cat/ ).

daily

Boolean flag. Are data to be returned at a daily or hourly scale?

date

An object of class Date. By default the current day in the case of downloadSMCcurrentday(). In the case of downloadSMCstationlist() a date for which operational stations are queried. In the case of downloadSMChistorical, the function returns the whole month the first date selected is in (implementation in package meteospain).

station_id

A string vector containing station ids (the list of stations for which climatic series are available is given by downloadSMCstationlist()). If NULL, all available stations are queried. Otherwise, only the data corresponding to the specified stations will be returned.

export

If export = FALSE the downloaded data is stored in memory. Otherwise the result is written on the disk (using the format specified in exportFormat).

exportDir

Output directory for downloaded meteorology.

exportFormat

Format of meteorological data. Current accepted formats are "castanea" and "meteoland".

metadataFile

The name of the file that will store the meta data describing all written files.

verbose

Boolean flag to print process information.

Details

API key needs to be requested from SMC (https://apidocs.meteocat.gencat.cat/).

Value

Function downloadSMCstationlist returns a SpatialPointsDataFrame-class object containing the list of SMC operational weather stations for the date given.

Function downloadSMCcurrentday downloads recent weather (the last 24h or the weather for a given date) from all currently available stations and returns data frame if daily_meteoland = FALSE or a SpatialPointsDataFrame-class object with observations aggregated at the daily scale otherwise.

Function downloadSMChistorical downloads historical daily weather corresponding to a given time period from a set (or all currently available) stations. Results are returned (or exported) after formatting data as a SpatialPointsMeteorology-class if variable_code = NULL, or as a data frame otherwise.

Note

Since ver. 1.0.1, weather data download functions included in meteoland make internal calls to functions in package meteospain. For an enhanced flexibility, users are recommended to call functions in meteospain themselves, and then to use function reshapemeteospain to generate data suitable for meteoland.
