PRECIS: a regional climate modelling system
PRECIS is a regional climate modelling system developed at the Met Office Hadley Centre with the intention of allowing users in developing countries to easily produce detailed climate projections for any chosen region of the world. PRECIS is designed to run a Linux PC so does not require extensive IT infrastructure.
The latest version of PRECIS (PRECIS 2.0) was released in 2016. Updates include faster model executable and new driving GCMs (including the first of a series of CMIP5 global models, and three members of the 20th Century Reanalysis version 2c) and lots of other improvements. If you are a current PRECIS user and would like to receive PRECIS2.0 see PRECIS user support.
