PRECIS Newsletter January 2012
PRECIS Discussion Board
If you are a PRECIS user, we have switched over to providing PRECIS tech support via an internet forum. As this builds up over the years it will provide a searchable index for PRECIS users to check to find solutions - and thus to help each other!
You will need to register on the PRECIS discussion board to submit a post. To join:
- Please register by visiting climateprediction.net/board and click on "Register" in the top right hand corner of the page.
- Once you have received your registration email and followed its instructions, email precis your name, institute and username. We need your username so we can add you to the list of users who can view and post on the forum!
- When you have been added, you can use this direct link climateprediction.net/board/viewforum.php?f=59 to view the PRECIS board.
Please keep us up to date
We would like to know the status of your work with PRECIS! Please could you send us any publications, papers, posters or presentations related to PRECIS to precis or advertise them on the PRECIS discussion board and let us know if we can put them on the PRECIS related links page. This could be a great opportunity to share your work with the worldwide PRECIS community! A list of all the know PRECIS publications can be found on this page.

News & Announcements
Update on PRECIS Versions
- PRECIS 1.9.3
PRECIS 1.9.3 is the latest PRECIS version and was distributed at the PRECIS workshop at Reading University (UK) in August 2011. Version 1.9.3 includes a new executable for the HadRM3P regional model which can operate up to 25% faster. HadRM3Q0 has been removed due to occasional model instabilities as described in the last newsletter. Version 1.9.3 includes support to drive PRECIS with the ACRE-facilitated 20th Century Reanalysis.
A new program has recently been developed at Reading University which converts PP format data to CF-compliant NetCDF format. It includes support for the rotated pole (the native grid of output data from PRECIS) within the NetCDF metadata. If you would like to help test this software, please let us know.
- PRECIS 2.0
PRECIS 2.0 will be released in 2012. Version 2.0 will include the ability for PRECIS to be driven by a subset of CMIP5 GCM experiments (GCMs which will inform the upcoming IPCC fifth assessment report). The first CMIP5 model to be made available for use with PRECIS 2.0 will be HadGEM2-ES, the Hadley centre's earth-system model. Other CMIP5 models will be made available is due course, allowing users to select and downscale a sub-set of the ensemble. Version 2.0 will also feature a faster regional model executable and an improved user interface.
PRECIS-related Workshops and Training
- Climate Education (Online Training)
The PRECIS team have been working with the University of Oxford Continuing Education Department to create two short online courses. The first of these courses "An Introduction to the Science of Climate and Climate Change" is now available and can be taken free of charge by anyone. The second course is under construction and will look more specifically at regional climate modelling. Course 2 will be available later in the year. Visit climateeducation.net for more information.
- UK, 23rd-27th April 2012
The next PRECIS workshop will occur at the University of Reading (UK) in April. If you are interested in attending please contact precis.
- SAIN & ACCC PRECIS Workshop, China, November 2011
The PRECIS team ran two workshops hosted by SAIN and ACCC which focused on the analysis of regional model output data from PRECIS for research into climate change impacts on agriculture in China
- QUMP ensemble sub-selection
If you are planning to work with the HadCM3Q 17-member GCM ensemble, please bear in mind that we do not release boundary data from all 17 GCMs. Instead, PRECIS users wishing to use HadCM3Q should undertake a scientifically based selection process towards choosing 4-6 members from the ensemble. This allows users to explore the range of uncertainty in projections while reducing the need to store, transfer and analyse large amounts of data. Please see the QUMP with PRECIS page for advice on how to make a selection and the procedure for requesting boundary data.
- Global Model Availability at BADC
You can now download a selection of daily and monthly mean output data from HadCM3Q(0-16) global model output data from the British Atmospheric Data Centre ( BADC). This data is useful for selection of appropriate subsets of the 17 member HadCM3Q ensemble for experimental design as well as for validation of PRECIS experiments which have utilised HadCM3Q(0-16) as their driving GCM. Please click here for instructions and information on the BADC data.
- Storm tracking functionality
If you are interested in utilising PRECIS toward tropical cyclone detection and tracking, contact us at precis for more information.
- PP Analysis Utilities for Windows
The PRECIS analysis tools package for PP format data has been ported to run within Microsoft Windows, enabling the full capability of the statistical and analysis software included with PRECIS within Windows XP/Vista/7 (32 or 64 bit versions). If you are interested in a copy please email us at precis.
- Sharing of the PRECIS Output Data
Are you willing to share your PRECIS output data? If so please email us at precis as we may be able to help facilitate sharing the PRECIS output data by providing web space and transfer media.
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).
