PPPY (Physical Parametrizations with PYthon)

PPPY is a python tool designed to test parameterizations in offline mode. In particular, it has been used to execute the microphysical ICE parameterization of AROME/Meso-NH on a single point in order to simulate a temporal evolution due solely to this parameterization. This framework has allowed to correct time-step dependencies in the implementation of the parameterization. The tool was also used to evaluate and compare sedimentation formulations (in 1D mode).
