Retrieve hourly averages, daily maximums, or daily minimums of pollution data in the original units, by station, from the air quality server at Consulta de Concentraciones

get_station_month_data(criterion, pollutant, year, month)

## Arguments

criterion Type of data to download. "HORARIOS" - Hourly data "MAXIMOS"" - Daily maximums "MINIMOS" - Daily minimums The type of pollutant to download. "SO2" - Sulfur Dioxide (parts per billion) "CO" - Carbon Monoxide (parts per million) "NOX" - Nitrogen Oxides (parts per billion) "NO2" - Nitrogen Dioxide (parts per billion) "NO" - Nitric Oxide (parts per billion) "O3" - Ozone (parts per billion) "PM10" - Particulate matter 10 micrometers or less (micrograms per cubic meter) "PM25" - Particulate matter 2.5 micrometers or less (micrograms per cubic meter) "WSP" - Wind velocity (meters per second) "WDR" - Wind direction (degrees) "TMP" - Temperature (degrees Celsius) "RH" - Relative humidity (percentage) an integer indicating the year for which to download data (the earliest possible value is 1986) month number to download

## Value

A data.frame with pollution data, the hours correspond to the Etc/GMT+6 timezone, with no daylight saving time

## Details

Temperature (TMP) data was rounded to the nearest integer, but the get_station_data function allows you to download data accurate to one decimal point in some cases (i.e. for old data).

## Warning

The data for the current month is in the process of being validated

stations for a data.frame with the location and names of all pollution measuring stations

Other raw data functions: get_station_data
