Can I use the FEH Web Service outputs with the ReFH Spreadsheet?

The ReFH spreadsheet is no longer supported, and distribution has ceased. Its methods have now been superseded and are no longer recommended for use. As an end-of-life product there have been no attempts to ensure that it is compatible with newer operating systems.

The updated ReFH 2 methods, including the use of the latest rainfall estimation and urbanisation models, are incorporated in our ReFH 2 software.
