A Quick Reminder: What is PRECIS?

PRECIS (Providing REgional Climates for Impacts Studies) is a regional climate modelling system allowing Hadley Centre regional climate models to be set up over any region and run on a PC (under the Linux operating system) with a simple user interface. It also includes a suite of data processing, analysis and display tools so experiments can easily be set up, run, analysed and data made available for wider application and dissemination. PRECIS is designed for researchers (with a focus on developing countries) to construct high-resolution climate change scenarios for their region of interest. These scenarios can be used in impact, vulnerability and adaptation studies, and to aid in the preparation of National Communications, as required under Articles 4.1 and 4.8 of the United Nations Framework Convention on Climate Change (UNFCCC).


The PRECIS team want to remind existing users of PRECIS that they are entitled to receive an upgrade to the newest version of PRECIS (currently 1.8.2). An install DVD of 32-bit OpenSuse 11.1 Linux, the recommended distribution of Linux for PRECIS, can be included on request.

Once the model is installed and run with approximately a model year of sample data from the ERA-15 reanalysis, the boundary conditions necessary to run PRECIS can be provided on hard drive. Please contact with any questions or comments.

Please refer to the PRECIS FAQ and How to Obtain PRECIS for further information.
