Abstract/Summary

The purpose of this report is to compare two river flow routing schemes, TRIP and G2G, for use in global and regional climate models. TRIP is the Total Runoff Integrating Pathways scheme developed by [Oki et al., 1999]; G2G is the Grid-to-Grid routing scheme designed by [Bell et al., 2007]. In this report, the two routing schemes are tested offline using surface and sub-surface runoff data from JULES forced with GSWP-2 data. The performance of each routing model is evaluated against observed data, where available, for ten of the largest river catchments globally. The model outputs are also compared when forced with runoff data produced by HadGEM3.
