A better understanding of the role of TCs within the climate system requires a fully coupled modeling framework, where TC-... CGD Affiliations: CCR Publication Genre: Article View on OpenSky |

Implementation and evaluation of irrigation techniques in the Community Land Model Yao, Y., Vanderkelen, I., Lombardozzi, D., Swenson, S., Lawrence, D. M., et al. (2022). Implementation and evaluation of irrigation techniques in the Community Land Model. Journal of Advances in Modeling Earth Systems, doi:https://doi.org/10.1029/2022MS003074 Several previous studies have highlighted the irrigation-induced impacts on the global and regional water cycle, energy budget, and near-surface climate. While land models are widely used to address this question, the implementations of irr... CGD Affiliations: TSS, CGDDEPT Publication Genre: Article View on OpenSky |
