Principal coefficients of EOFs
eofcoeff.RdThis module calculates the time series of the principal coefficients for given EOF (empirical orthogonal functions) and data. Time steps in infile1 are assumed to be the EOFs, time steps in infile2 are assumed to be the time series. Note, that this operator calculates a non weighted dot product of the fields in infile1 and infile2. For consistency set the environment variable CDO_WEIGHT_MODE=off when using eof or eof3d. There will be a separate file containing a time series of principal coefficients with time information from infile2 for each EOF in infile1. Output files will be numbered as <obase><neof><suffix> where neof+1 is the number of the EOF (timestep) in infile1 and suffix is the filename extension derived from the file format.
