rdefra: Interact with the UK AIR Pollution Database from DEFRA. The package rdefra allows to retrieve air pollution data from the Air Information Resource UK-AIR of the Department for Environment, Food and Rural Affairs in the United Kingdom. UK-AIR does not provide a public API for programmatic access to data, therefore this package scrapes the HTML pages to get relevant information. This package follows a logic similar to other packages such as waterData and rnrfa: sites are first identified through a catalogue, data are imported via the station identification number, then data are visualised and/or used in analyses. The metadata related to the monitoring stations are accessible through the function ukair_catalogue(), missing stations’ coordinates can be obtained using the function ukair_get_coordinates(), and time series data related to different pollutants can be obtained using the function ukair_get_hourly_data(). DEFRA’s servers can handle multiple data requests, therefore concurrent calls can be sent simultaneously using the parallel package. Although the limit rate depends on the maximum number of concurrent calls, traffic and available infrustracture, data retrieval is very efficient. Multiple years of data for hundreds of sites can be downloaded in only few minutes. For similar functionalities see also the openair package, which relies on a local copy of the data on servers at King’s College (UK), and the ropenaq which provides UK-AIR latest measured levels (see https://uk-air.defra.gov.uk/latest/currentlevels) as well as data from other countries.
