Import data from the Scottish Air Quality Network
Usage
importSAQN(
site = "gla4",
year = 2009,
data_type = "hourly",
pollutant = "all",
meta = FALSE,
meteo = TRUE,
ratified = FALSE,
to_narrow = FALSE,
progress = TRUE
)
Arguments
- site
Site code of the site to import e.g. “gla4” is Glasgow Kerbside. Several sites can be imported with
site = c("gla4", "gla5")
--- to import Glasgow Kerbside and Anderston, for example.- year
Year or years to import. To import a sequence of years from 1990 to 2000 use
year = 1990:2000
. To import several specific years useyear = c(1990, 1995, 2000)
for example.- data_type
The data type averaging period. These include:
"hourly" Default is to return hourly data.
"daily" Daily average data.
"monthly" Monthly average data with data capture information for the whole network.
"annual" Annual average data with data capture information for the whole network.
"15_min" To import 15-minute average SO2 concentrations.
"8_hour" To import 8-hour rolling mean concentrations for O3 and CO.
"24_hour" To import 24-hour rolling mean concentrations for particulates.
"daily_max_8" To import maximum daily rolling 8-hour maximum for O3 and CO.
"daqi" To import Daily Air Quality Index (DAQI). See here for more details of how the index is defined.
- pollutant
Pollutants to import. If omitted will import all pollutants from a site. To import only NOx and NO2 for example use
pollutant = c("nox", "no2")
.- meta
Should meta data be returned? If
TRUE
the site type, latitude and longitude are returned.- meteo
Should modelled meteorological data be returned if available. The default is
TRUE
and will return wind speed (ws
), wind direction (wd
) and ambient temperature (air_temp
). The variables are calculated from using the WRF model run by Ricardo Energy & Environment and are available for most but not all networks. Settingmeteo = FALSE
is useful if you have other meteorological data to use in preference e.g. fromworldmet
.- ratified
If
TRUE
columns are returned indicating when each species was ratified i.e. quality-checked. Available for hourly data only.- to_narrow
By default the returned data has a column for each pollutant/variable. When
to_narrow = TRUE
the data are stacked into a narrow format with a column identifying the pollutant name.- progress
Show a progress bar when many sites/years are being imported? Defaults to
TRUE
.
