Multiyear seasonal arithmetic — cdo

This module performs simple arithmetic of a time series and one timestep with the same season. For each field in infile1 the corresponding field of the timestep in infile2 with the same season 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 YSEASSTAT.

Usage

cdo_yseasadd(ifile1, ifile2, ofile = NULL)

cdo_yseasdiv(ifile1, ifile2, ofile = NULL)

cdo_yseasmul(ifile1, ifile2, ofile = NULL)

cdo_yseassub(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.
