CISL & NCAR Announces “CMIP Analysis Platform”

The following message was sent out to potential users to inform them of the recent announcement of a new service made available from CISL and NCAR, with support from NSF, to the community of atmospheric, climate, and related sciences. Please share this with any colleagues or students who may be interested.

David L. Hart, NCAR/CISL User Services Manager, writes:

The Computational and Information Systems Laboratory (CISL) and NCAR, with support from NSF, are making available a platform to support analysis of large-scale CMIP5 data. The new CMIP Analysis Platform encompasses the Geyser and Caldera analysis clusters, the GLADE disk system, and up to 500 TB of CMIP5 data, which includes all the CMIP5 data published by NCAR and will include other CMIP5 data requested by users.

The goal of the CMIP Analysis Platform is to support analysis that would otherwise be difficult or impossible for university researchers to conduct, either because of a lack of disk space or lack of analysis software or computing capability.

These challenges will only increase with the even larger data sets expected from the forthcoming CMIP6 activities. CISL is using CMIP5 data to roll out the CMIP Analysis Platform and prepare for a larger-scale environment to be deployed for analysis of CMIP6 data.

The CMIP Analysis Platform is available to any researcher who is eligible for a small university allocation, which includes scientists with NSF awards as well as graduate students and postdoctoral researchers pursuing their dissertation or postdoctoral projects. Users with existing projects on the Yellowstone environment can also access the CMIP5 data.

Interested users can request allocations on the CMIP Analysis Platform and request CMIP5 data sets to be added to the file system. CISL staff will locate the data and add it to the GLADE space. Users can then use the Geyser and Caldera systems to perform their analyses. To support the widest possible range of research, data sets will be rotated in and out regularly based on user requests and demand for the various sets of data.

To learn more about the CMIP Analysis Platform, to request allocations or data sets, or to browse the currently available data, see the CMIP Analysis Platform documentation at https://www2.cisl.ucar.edu/docs/cmip_ap.

Daily Precipitation and Surface Temperature Data to be Added for Historical and RCP 8.5 Experiments.

By popular request, daily 2D precipitation and surface temperature data are soon to be added for both the Historical and RCP 8.5 experiments. These datum will be comprise the first daily time frequency data to be provided by the CMIP5 Community Storage Server. Stay tuned for more updates on the availability of this data.

Data Citation & Acknowledgements Page Added

If you acquire model output data via the WHOI CMIP5 Community Storage Server, we ask that you acknowledge us in the use of your data. This may be done by including the following text in any documents or publications using these data.

CMIP5 model output data provided by the WHOI CMIP5 Community Storage Server, Woods Hole Oceanographic Institution, Woods Hole, MA, USA from their website at http://cmip5.whoi.edu/ (WHOI internal use only).

We would also appreciate receiving a copy of the relevant publications. This will help to justify continued support and future development of the WHOI CMIP5 Community Storage Server. Thank you!

Advanced Dataset Search Documentation Added

The easiest way to find the files you’re looking for is to use the CMIP5 Community Storage Server – Advanced Dataset Search page. This page provides free-text and faceted search functionality of all available data files and a dynamic, paginated result table. FTP and HTTP links to the data files are provided in the result table to allow users to download files of interest directly from the search page. Additionally, the result set – including paths and file names – may be downloaded in a variety of different formats including CSV, JSON, PHP, Python, and XML.

For more information on how to use the search page, see the Advanced Dataset Search: User Manual.
