Multiyear daily arithmetic — cdo

This module performs simple arithmetic of a time series and one timestep with the same day of year. For each field in infile1 the corresponding field of the timestep in infile2 with the same day of year is used. The input files need to have the same structure with the same variables. Usually infile2 is generated by an operator of the module YDAYSTAT.

Usage

cdo_ydayadd(ifile1, ifile2, ofile = NULL)

cdo_ydaydiv(ifile1, ifile2, ofile = NULL)

cdo_ydaymul(ifile1, ifile2, ofile = NULL)

cdo_ydaysub(ifile1, ifile2, ofile = NULL)

Arguments

ifile1, ifile2: Strings with the path to the input files.
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.
