FORP-NP10 version4.5

Future Ocean Regional Projection (FORP) datasets were produced by high-resolution regional ocean model simulations with ensemble atmospheric forcings from Coupled Model Intercomparison Project Phase 5 (CMIP5) models and scenarios. These were developed by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Meteorological Research Institute, Japan Meteorological Agency. The development of FORP were supported by Social Implementation Program on Climate Change Adaptation Technology (SI-CAT, grant no.: JPMXD0715667163) and Integrated Research Program for Advancing Climate Models (TOUGOU, grant no.: JPMXD0717935561), the Ministry of Education, Culture, Sports, Science and Technology (MEXT). Further we expanded the FORP datasets with two other CMIP5 model used as forcing data in the Advanced Studies of Climate Change Projection (SENTAN Program). Meteorological Research Institute Community Ocean Model version 4 (MRI.COMv4; Tsujino et al. 2017) was used for the regional ocean models. FORP-NP10 is a historical and future ocean projection dataset in the North Pacific Ocean with an approximately 10 km horizontal resolution, produced by continuous simulation from 1970 to 2100. In the version 4.5 dataset (FORP-NP10 version4.5), the atmospheric forcings for the FORP simulations were from two climate models from CMIP5, GFDL-ESM2M and IPSL-CM5A-MR, with historical (1981-2005), RCP2.6 (2006-2100), and RCP8.5 (2006-2100) scenarios. By using FORP version 4 and version 4.5 together, the number of ensembles increases and can be used to evaluate the uncertainty of future projections.
