MCRN and CliMathNet have an organizational collaboration funded by the National Science Foundation under the Science Across Virtual Institutes (SAVI) program.

CliMathNet is a network, based in the United Kingdom, which aims to bring together Climate Scientists, Mathematicians and Statisticians to answer the key questions around climate modeling (in particular understanding and reducing uncertainties in observation and prediction).This is an area of science that ranges from numerical weather prediction to the science underpinning the Intergovernmental Panel for Climate Change (IPCC).
