This module multiplies or divides each timestep of a dataset with the corresponding days per month or days per year. The result of these functions depends on the used calendar of the input data.

Usage

cdo_divdpm(ifile, ofile = NULL)

cdo_divdpy(ifile, ofile = NULL)

cdo_muldpm(ifile, ofile = NULL)

cdo_muldpy(ifile, ofile = NULL)

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.

Arguments

ifile

String with the path to the input file.

ofile

String with the path to the output file.

Details

muldpm  Multiply with days per month
        o(t,x) = i(t,x) * days_per_month
divdpm  Divide by days per month
        o(t,x) = i(t,x) / days_per_month
muldpy  Multiply with days per year
        o(t,x) = i(t,x) * days_per_year
divdpy  Divide by days per year
        o(t,x) = i(t,x) / days_per_year
