The Land Model Working Group of the Community Climate Systems Model (CCSM) has completed a prototype core single-column land model, designated the Community Land Model (CLM), and has demonstrated its success, as well as identified areas for further improvement. One of the areas that requires immediate improvement is runoff. The PI has developed an improved treatment of grid-scale run off by accounting for topographic influence on soil moisture heterogeneity and run off characteristics. Preliminary testing on regional and global scales shows the model performs satisfactorily. Under this award, the PI will complete testing/finalizing of the runoff scheme in CLM, and ensure its successful implementation in CSM. The work is important because it should provide a strong diagnostics underpinning to the CCSM project from a university based group engaged in dynamical diagnosis of observed climate variability.

社区气候系统模型(CCSM)土地模型工作组已经完成了一个核心单柱土地模型的原型，命名为社区土地模型(CLM)，并展示了其成功之处，以及确定了需要进一步改进的领域。需要立即改善的领域之一是径流。PI通过考虑地形对土壤水分非均质性和径流特征的影响，开发了一种改进的网格尺度径流处理方法。在区域和全球尺度上的初步测试表明，该模型的性能令人满意。根据这项合同，PI将在CLM中完成径流方案的测试/最终确定，并确保其在CSM中的成功实施。这项工作很重要，因为它应该为CCSM项目提供强有力的诊断支持，该项目来自一个从事观测到的气候变异性动态诊断的大学小组。
