airbaseStats: Import pre-calculated airbase statistics

Description

Import pre-calculated airbase statistics

Usage

airbaseStats(statistic = "Mean", pollutant = "no2", avg.time = "auto",
  code = NULL, site.type = c("background", "traffic", "industrial",
  "unknown"), year = 1969:2012, data.cap = 0, add = c("country", "lat",
  "lon", "site.type"))

Arguments

statistic

A single choice from P50, Mean, P95, P98, Max, Max36, Max8, Days.c.50., Max26, Days.c

pollutant

The single name of a pollutant to extract; can be upper or lower case but must match one of those below.

avg.time

The averaging time on which the measurements are based. By default the averaging period with most data associated with it is used. For most pollutants the averaging period will be day. Other common options are hour and

code

The airbase site code(s) to select. Can be upper or lower case.

site.type

The type of site(s) to select.

year

The year(s) to select e.g. year = 2000:2012 to select years 2010, 2011 and 2012.

data.cap

The data capture threshold to use (%). By default all data are selected.

add

Additional fields to add to the returned data frame. By default the country, site type, latitude and logitude are returned. Other useful options include city, site (site name), EMEP_station and al

Value

A data frame of airbase sites with the statsitics chosen and for all species.
Returns a data frame with POSIXct date, together with many other airbase fields.

Details

The airbase database makes available detailed pre-calculated statsitics for all species, sites and years. The airbaseStats function provides these data.

The data are imported depending on the statistic chosen --- see the list of available statistics in the statistics option. Further options are available to refine the selection including a single pollutant, year(s), site type(s), data capture percentage threshold and airbase site code.

Once the data have been imported it is then possible to subset the data in various ways e.g. by extracting a particular species with a defined data capture threshold.
