What is the CCF? A non-profit founded in 2010, based in the UK; Continuing projects started in 2008; A few software consultants, currently unpaid part-time; Advisory committee of a dozen experts; A growing network of climate scientists and others; Several projects and publications; and big plans. Nick Barnes talk at ICES, climatecode.org

Foundation goals "to promote public understanding of climate science, by increasing the visibility and clarity of the software used in climate science, and by encouraging climate scientists to do the same; by encouraging good software development and management practices among climate scientists; by encouraging the publication of climate science software as open source.” Nick Barnes talk at ICES, climatecode.org

What is the problem? Scientists have to write code, but: They aren’t well-trained; They aren’t rewarded; There is no incentive to publish it. The public need to know about climate science, but: The science isn’t accessible; The practices aren’t always transparent; They are lied to about ‘tricks’ and secrecy. Nick Barnes talk at ICES, climatecode.org

Clear Climate Code Over-riding goal is clarity: code which interested members of the public can download, run, read and understand. Open-source, of course. First target NASA GISTEMP: ccc-gistemp.googlecode.com 12 KLOC of Fortran (etc) lines of Python (including 1500 of docstrings) fixed minor bugs. fosters new science: one paper in press, two draft. Nick Barnes talk at ICES, climatecode.org

Homogenization project GHCN 3.0 dataset (Menne & Williams 2009); Re-implemented by Dan Rothenberg (grad student at MIT); Working with Menne and Williams at NCDC; Algorithm improved, bugs fixed, creating GHCN 3.1; Funded by Google (Summer of Code); Praised by NCDC, who are interested in doing more. Nick Barnes talk at ICES, climatecode.org

Common Climate Project Web framework for visualizing climate datasets; Late Holocene paleoclimatology: Emile-Geay (USC), Smerdon & Anchukaitis (LDEO); Open-source, open datasets; Prototype online at commonclimate.net; Implemented by Hannah Aizenman (grad student at CUNY); Funded by Google (Summer of Code). Nick Barnes talk at ICES, climatecode.org

Future Plans Changing policies: Transparency; Rewards for all research products. Training scientists: Basic techniques (testing, version control, agile, etc); Code publication and reuse. Providing resources: White papers, blog posts; Directories. Building networks; Leading by example: ccc-gistemp; ccf-homogenization; etc…. Nick Barnes talk at ICES, climatecode.org
