This operator computes the yearly mean of a monthly time series. Each month is weighted with the number of days per month. The time of outfile is determined by the time in the middle of all contributing timesteps of infile. For every adjacent sequence t_1, ...,t_n of timesteps of the same year it is: o(t,x) = mean{i(t',x), t_1<t'<=t_n}
cdo_yearmonmean(ifile, ofile = NULL)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.
String with the path to the input file.
