The software available here is discussed in the paper:

Barbara Tomassetti, Marco Verdecchia and Filippo Giorgi, NN5: A Neural Network based approach for the downscaling of precipitation fields. Model description and preliminary results The binary file containing the optimized weights is available here.
The free fortran code is available here and can be compiled using No other platforms have been checked.
A very quick description of the utility is available in the header of the fortran code. Authors are grateful to Leif Lombladd for providing the jetnet package source code (see Lombladd et al., 1991 referenced in the above cited paper).
