  • Okada, M., T. Iizumi, M. Nishimori, and M. Yokozawa, 2009: Mesh climate change data of Japan Ver.2 for climate change impact assessments under IPCC SRES A1B and A2. Journal of Agricultural Meteorology, 65. In press.

The Intergovernmental Panel on Climate Change (IPCC) published the Fourth Assessment Report (AR4) in 2007 and stated that recent climate change and variation are induced by increases in the atmospheric greenhouse gases (GHG) concentration due to anthropogenic activities. The report includes the results of impact assessments on a wide range of sectors. The assessments have been conducted based on future climate projections, which refer to aspects of the future climate evaluated by Atmosphere-Ocean Coupled General Circulation Models (CGCMs). The projection data used in the AR4 are archived under the Program for Climate Model Diagnosis and Intercomparison (PCMDI) promoted by the U.S. Department of Energy. We interpolated the projection data around Japan and constructed a dataset entitled "Mesh climate change data of Japan Ver.2" for climate change impact study. Nine projections performed by seven models under the A1B and A2 of the Special Report on Emissions Scenarios (SRES) were implemented for the dataset. They consist of mesh data with a size of 7.5' in longitude and 5.0' in latitude, i.e., approximately 10 x 10 km (45" in longitude and 30" in latitude, i.e., approximately 1 x 1 km, for one high-resolution model). The dataset includes five climatic elements, i.e., the daily mean, maximum, and minimum surface air temperatures, daily total precipitation, and daily accumulated shortwave radiation for three periods, 1981-2000, 2046-2065, and 2081-2100. This article describes the details on the construction and characteristics of the data.
