Get DEFRA UK-AIR stations metadataSource:
This function fetches the catalogue of monitoring stations from DEFRA's website.
ukair_catalogue( site_name = "", pollutant = 9999, group_id = 9999, closed = "true", country_id = 9999, region_id = 9999, location_type = 9999 )
This is the name of a specific site. By default this is left blank to get info on all the available sites.
This is a number from 1 to 10. Default is 9999, which means all the pollutants.
This is the identification number of a group of stations. Default is 9999 which means all available networks.
This is "true" to include closed stations, "false" otherwise.
This is the identification number of the country, it can be a number from 1 to 6. Default is 9999, which means all the countries.
This is the identification number of the region. 1 = Aberdeen City, etc. (for the full list see https://uk-air.defra.gov.uk/). Default is 9999, which means all the local authorities.
This is the identification number of the location type. Default is 9999, which means all the location types.
