Generating Input Data
#####################

Generally, AceCAST, like WRF requires certain parameters to exist in the input data. For a list of these parameters
please refer to the `WRF Forum <https://forum.mmm.ucar.edu/phpBB3/viewtopic.php?t=5381>`_. Below we provide a short list
of free and paid locations to retrieve input data from.
