GRENE-TEA Model Intercomparison Project (GTMIP)
  1. Overview

      2. The goals of the modeling group in the terrestrial ecosystem research project of the GRENE Arctic Climate Change Research Project (GRENE-TEA; Fig.1) are to a) feed to the coupled global climate model　(CGCM) research project for the possible improvement of the physical and ecological processes for the Arctic terrestrial modeling (excl. glaciers and ice sheets) in the extant terrestrial schemes in the CGCMs , and b) lay the foundations of the future-generation Arctic terrestrial model development. To achieve these goals the GTM (modeling group in GRENE-TEA) group is to conduct a model intercomparison project (GTMIP) among the participating models, in which we will utilize the GRENE-TEA site observations data (stage 1) and CGCMs outputs (stage 2) for driving and validating the models. The GTMIP is designated to 1) enhance communications and understanding of the “mind and hands” between the modeling researchers and field scientists, 2) assess the uncertainty and variations stemmed from the extant model implementation/designation, and the variability due to climatic and historical conditions among the Arctic sites, and 3) feed such information and evaluations to the future-generation Arctic terrestrial model development.
