ydaypctl: Multiyear daily percentile values

In rcdo: Wrapper of 'CDO' Operators

Multiyear daily percentile values

Description

This operator writes a certain percentile of each day of year in infile1 to outfile. The algorithm uses histograms with minimum and maximum bounds given in infile2 and infile3, respectively. The default number of histogram bins is 101. The default can be overridden by setting the environment variable CDO_PCTL_NBINS to a different value. The files infile2 and infile3 should be the result of corresponding ydaymin and ydaymax operations, respectively. The date information in an output field is the date of the last contributing input field. o(001,x) = pth percentile {i(t,x), day(i(t)) = 001} ... o(366,x) = pth percentile {i(t,x), day(i(t)) = 366}

Usage

cdo_ydaypctl(ifile1, ifile2, ifile3, p = NULL, ofile = NULL)

Arguments

ifile1, ifile2, ifile3	Strings with the path to the input files.
p	FLOAT - Percentile number in {0, ..., 100}
ofile	String with the path to the output file.

Value

Operators that output one or more files return a character vector to the output files.

Operators that output an indefinite number of files return a string with the basename of the files.

Operatos that don't return filenames return a character vector with the string output.
