The MAPP Program's Coupled Model Intercomparison Project, Phase 5 (CMIP5) Task Force brings together scientists whose MAPP-funded research in the framework of CMIP5 aims at evaluating simulations of the 20th century climate and the uncertainties in long-term predictions and projection of twenty-first century climate over North America. It is envisioned that CMIP5 Task Force activities will advance knowledge of long-term climate outlooks for North America. The MAPP CMIP5 Task Force will coordinate with other relevant national and international efforts (e.g. WCRP Panels such as WGCM and WGNE, the National Climate Assessment).
The CMIP5 Task Force was initiated on November 1st 2011 and will have a duration of 3 years.

The Task Force is focused on two activities: an interaction with the National Climate Assessment (NCA) and process-oriented metrics for climate model evaluation. The first activity stems from a workshop on CMIP hosted by the USGCRP Interagency Group on Integrative Modeling in College Park, MD in the Fall of 2013. The Task Force is answering NCA questions on CMIP5 projections for North America, applying findings from research projects funded under the Task Force. The second activity is focused on developing process-oriented metrics for the evaluation of climate models. A number of major national modeling centers have been engaged with the Task Force on next-generation process-oriented metrics that could be used for model development.
Progress to date (November 5th, 2013)
- CMIP5 Task Force leadership organized a Journal of Climate "CMIP5 special collection on North American climate" which includes CMIP5-based studies on North American climate and relevant global climate phenomena like ENSO, MJO, Arctic Oscillation that affect North America. Twenty-one papers from CMIP5 Task Force investigators are included in the Special Collection. Please visit the Papers Submitted for Publication page to view the papers that are currently under review. Three overview papers were prepared for the Special Collection summarizing the work of the CMIP5 Task Force investigators. Their titles are as follows:
- North American Climate in CMIP5 Experiments. Part I: Evaluation of Historical Simulations of Continental and Regional Climatology
- North American Climate in CMIP5 Experiments. Part II: Evaluation of Historical Simulations of Intra-Seasonal to Decadal Variability
- North American Climate in CMIP5 Experiments: Part III: Assessment of 21st Century Projections
- At the 2014 AMS Annual Meeting, the Task Force will host a session titled "CMIP5 models: NOAA CMIP5 Task Force Session on Process-Oriented Diagnostics (Part I)" (Session 1A in the 26th Conference on CVC). Task Force participants and representatives from the national modeling centers will present on their work related to process-oriented metrics for climate model evaluation.
- An AGU 2012 Fall meeting session titled "North American Climate in CMIP5 Experiment" (A056) has been proposed by the CMIP5 Task Force and will feature many presentations from this group.
- Preliminary results from the CMIP5 Task Force were presented at the WCRP Workshop on CMIP5 Model Analysis, 5-9 March 2012 Honolulu, Hawaii, USA.
