importEurope: Import air quality data from European database
Description
This function is a simplified version of the saqgetr package (see
https://github.com/skgrange/saqgetr) for accessing European air quality
data. The function only returns valid hourly data and is meant as a fast and
convenient way of accessing the most common type of hourly air quality data.
The function works in the same way as other openair functions that
import air quality data that generally need a site code and year to be
supplied.
Usage
importEurope(
site = "debw118",
year = 2018,
tz = "UTC",
meta = FALSE,
to_narrow = FALSE,
progress = TRUE
)
Year or years to import. To import a sequence of years from 1990
to 2000 use year = 1990:2000. To import several specific years use
year = c(1990, 1995, 2000) for example.
tz
Not used
meta
Should meta data be returned? If TRUE the site type,
latitude and longitude are returned.
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.
Details
The function can however return key site meta data.
The saqgetr package is much more comprehensive and provides data at
other time averages e.g. daily data.
