The Updated Smith-Feddes Model (User's Guide)

Abstract

The revisions made to the S-F computer code, so that it would accept the RTNEPH cloud data format instead of the 3DNEPH cloud data format. This computer program implements the updates, corrections and recommendations to the cloud microphysics which resulted from the examination of the microphysics parameterizations used in the model. This S-F program uses height of cloud base and top, cloud type, cloud cover percentage, presence of precipitation and vertical profiles of temperature and pressure to provide vertical profiles of cloud condensed moisture content (CMC) and the distribution of cloud particle number concentration by particle size. When precipitation is present, the same information is provided for the precipitation, both in-cloud and below cloud base to the ground. Keywords: Cloud microphysics; Measurements; Cloud drop-size distribution; Entrainment; Moist adiabatic process.
