INQC (version 2.0.5)

selepe: QC for Atmospheric Pressure (PP)

Description

This function will centralize temperature-like QC routines. It will create a file in the folder QC with an additional 0/1 column where "1" means test failed.

Usage

selepe(
  element = "PP",
  large = 15000,
  small = 8000,
  maxjump = 2000,
  maxseq = 3,
  margina = 0.999,
  level = 5,
  window = 30,
  roundmax = 10,
  blockmanymonth = 15,
  blockmanyyear = 180,
  blocksizeround = 20,
  qjump = 0.999,
  tjump = 1.5,
  inisia = FALSE
)

Arguments

element

two-letters ECA&D code for the element (PP for sea level pressure)

large

value above which the observation is considered physically impossible for the region

small

value below which the observation is considered physically impossible for the region

maxjump

forcing for jumps2() in absolute mode (in the same units of the variable). Passed on to jumps2(). See ?jumps2 for further details.

maxseq

maximum number of consecutive repeated values, for flat function (11.1,11.1,11.1 would be 3 consecutive values)

margina

tolerance margin, expressed as quantile of the differences, FUNCTION: newfriki(). Passed on to newfriki(). See ?newfriki for details

level

number of IQRs for IQR outliers

window

window, in days, for IQR outliers

roundmax

maximum number of consecutive decimal part value, for flat function (10.0, 11.0, 12.0 would be 3 consecutive values)

blockmanymonth

maximum number of equal values in a month, FUNCTION: toomany()

blockmanyyear

maximum number of equal values in a year, FUNCTION: toomany()

blocksizeround

maximum number of values in a month with the same decimal, for rounding function

qjump

quantile for jumps2() in quantile mode. Passed on to jumps2(). See ?jumps2 for further details

tjump

factor to multiply the quantile value for jumps2(). Passed on to jumps2(). See ?jumps2 for further details

inisia

a logical flag. If it is TRUE inithome() will be called

Value

results of QC for PP

Examples

# NOT RUN {
#Set a temporal working directory:
wd <- tempdir()
wd0 <- setwd(wd)
#Create subdirectory where raw data files have to be located
dir.create(file.path(wd, 'raw'))
options("homefolder"='./'); options("blend"=FALSE)
#Extract the ECA&D data and station files from the example data folder
path2pplist<-system.file("extdata", "ECA_blend_source_pp.txt", package = "INQC")
pplist<-readr::read_lines_raw(path2pplist)
readr::write_lines(pplist,'ECA_blend_source_pp.txt')
path2ppdata<-system.file("extdata", "PP_SOUID132729.txt", package = "INQC")
ppdata<-readr::read_lines_raw(path2ppdata)
readr::write_lines(ppdata, file=paste(wd,'/raw/PP_SOUID132729.txt',sep=''))
#Perform QC of Atmospheric Pressure data
selepe(inisia=TRUE)
#Remove some temporary files
list = list.files(pattern = "Rfwf")
file.remove(list)
#Return to user's working directory:
setwd(wd0)
#The QC results can be found in the directory:
print(wd)
# }
