subdaily_out_of_range {dataresqc}

Sub-daily big errors test

Description

Find the subdaily temperature (ta), wind speed (w), wind direction (dd), snow cover (sc), snow depth (sd) and fresh snow (fs) values that exceed thresholds selected by the user. The output is a list with the days in which ta, rr, dd, w, sc, sd or fs exceeds some threshold.

Usage

subdaily_out_of_range(
  subdailydata,
  meta = NULL,
  outpath,
  time_offset = 0,
  ta_day_upper = 45,
  ta_day_lower = -35,
  ta_night_upper = 40,
  ta_night_lower = -40,
  rr_upper = 100,
  rr_lower = 0,
  w_upper = 50,
  w_lower = 0,
  dd_upper = 360,
  dd_lower = 0,
  sc_upper = 100,
  sc_lower = 0,
  sd_upper = 200,
  sd_lower = 0,
  fs_upper = 100,
  fs_lower = 0
)

Arguments

subdailydata

A character string giving the path of the input file, or a 7-column matrix with following columns: variable code, year, month, day, hour, minute, value.

meta

A character vector with 6 elements: station ID, latitude, longitude, altitude, variable code, units. If subdailydata is a path, meta is ignored.

outpath

Character string giving the path for the QC results.

time_offset

Offset in hours to add to the time to obtain local time. By default, time_offset = 0.

ta_day_upper

is the ta maximum day threshold in degrees Celsius. By default, ta_day_upper = 45 C.

ta_day_lower

is the ta minimum day threshold in degrees Celsius. By default, ta_day_lower = -35 C.

ta_night_upper

is the ta maximum night threshold in degrees Celsius. By default, ta_night_upper = 40 C.

ta_night_lower

is the ta minimum night threshold in degrees Celsius. By default, ta_night_lower = -40 C.

rr_upper

is the rr maximum threshold in millimetres. By default, rr_upper = 100 mm.

rr_lower

is the rr minimum threshold in millimetres. By default, rr_lower = 0 mm.

w_upper

is the w maximum threshold in metres per second. By default, w_upper = 50 m/s.

w_lower

is the w mimumum threshold in metres per second. By default, w_lower = 0 m/s.

dd_upper

is the dd maximum threshold in degrees North. By default, dd_upper = 360.

dd_lower

is the dd minimum threshold in degrees North. By default, dd_lower = 0.

sc_upper

is the sc maximum threshold in percent. By default, sc_upper = 100%.

sc_lower

is the sc minimum threshold in percent. By default, sc_lower = 0%.

sd_upper

is the sd maximum threshold in centimetres. By default, sd_upper = 200 cm.

sd_lower

is the sd minimum threshold in centimetres. By default, sd_lower = 0 cm.

fs_upper

is the fs maximum threshold in centimetres. By default, fs_upper = 100 cm.

fs_lower

is the fs minimum threshold in centimetres. By default, fs_lower = 0 cm.

Details

The input file must follow the Copernicus Station Exchange Format (SEF).
