> establishing our own point release infrastructure.

> Bringing this project to Apache also immediately thrusts the ASF into the
> thriving ecosystem of the Coordinated Regional Downscaling Experiment
> (CORDEX), the US National Cimate Assessment, the North American Regional
> Climate Change Assessment Program (the US contribution to CORDEX) and into
> relevance for upcoming Intergovernmental Panel on Climate Change (IPCC)
> assessment activities at a number of different institutions. We also seek
> to help lead and encourage du jour standard development rather than top
> down level dictating of standards for climate software and the ASF will
> provide us a means for that.
> 
> === Initial Goals ===
> The initial goals of the proposed project are:
> 
> * Stand up a sustaining Apache-based community around the JPL RCMES
> codebase.
> * Active relationships and possible cooperation with related projects and
> communities, including end user and scientific communities, CORDEX,
> NARCCAP, US NCA, IPCC, ESG, etc.
> * Active relationships and possible cooperation with existing Apache
> communities, e.g., OODT, Hadoop/HIVE, Sqoop, Tika, SIS, etc.
> * Initial Apache release.
> * Leverage Apache Open Climate Workbench in climate activities at NASA,
> in the international community as mentioned above, and beyond.
> * Vetting all software licenses and making sure IP is clear (software
> grant from JPL forthcoming).

> === Community ===
> There is an existing, established community of developers and users of
> this projet. This includes established communities including the
> Coordinated Regional Downscaling Experiment, the U.S. National Climate
> Assessment (NCA), the North American Regional Climate Change Assessment
> Program (NARCCAP), and more. The Coordinated Regional Climate Downscaling
> Experiment (CORDEX, http://wcrp.ipsl.jussieu.fr/cordex/about.html) is a
> world wide effort of coordination of regional climate downscaling (RCD)
> experiments driven by the World Climate Research Program (WRCP,
> http://www.wcrp-climate.org/index.shtml). Recently, a large number of RCD
> projects have been carried out on a large parts of the world. To maximize
> the benefits of these research activities the WCRP designed a framework
> (Giorgi, WMO-Bulletin, 2009) focused on "quality-control [of] data sets of
> RCD-based information for the recent historical past and 21st century
> projections, covering the majority of populated land regions on the
> globe".  CORDEX defined different control domains (up to 10,
> http://cordex.dmi.dk/joomla/) for almost all the populated regions of the
> world in a way to standardize the experiments and make them comparable. A
> key region focused on Africa was also designated as the top priority by
> WRCP. CORDEX also provides a a series of conventions and list of variables
> that have to be followed by any project that wants to contribute to the
> experiment. Each CORDEX region has a coordinator and regional and
> international periodic meetings are scheduled in a way to ensure the
> global well being. NARCCAP is the U.S. contribution to CORDEX. From the
> [[http://www.globalchange.gov/what-we-do/assessment/nca-overview|US

> == Initial Source ==
> The project will start with seed code donated by NASA JPL via Mattmann and
> the rest of the initial committers, which consists of the Regional Climate
> Model Evaluation System (RCMES) toolkit, and the Climate Data eXchange
> (CDX) software. This will include the core Python API for RCMET, the RCMED

> source will also include Easy-RCMET, the Python Buildout for RCMET. In

> package that performs subsetting, access, regridding of climate data; and
> also includes a Python Buildout installer of its own called Uber CDX.
> 
> == Source and Intellectual Property Submission Plan ==
> All seed code and other contributions will be handled through the normal
> Apache contribution process. Mattmann has been authorized by NASA JPL to
> lead the contribution of RCMES and CDX into the Incubator via his existing
> Apache CLA, and a Software Grant to be provided.

> We will also contact other related efforts for possible cooperation and
> contributions.
