A high-resolution projected climate dataset for Vietnam: Construction and preliminary application in assessing future change

Abstract This study generates a daily temperature and precipitation dataset over Vietnam at high resolution of 0.1° for the historical period 1980–2005 future 2006–2100 under four representative concentration pathway (RCP) scenarios, namely RCP2.6, RCP4.5, RCP6.0, RCP8.5. The bias correction (BC) spatial disaggregation (SD) method is applied to outputs 31 global climate models (GCMs) Coupled Model Intercomparison Project Phase 5 (CMIP5) create new called CMIP5-VN. To guide BC SD steps, gridded data interpolated from observations 147 481 stations respectively are used. Results with CMIP5-VN show that warming projected continue till end 21st century all RCPs. average increase by 1.3±0.52 °C RCP2.6 3.85±0.85 RCP8.5 between 2080–2099 1986–2005. more intense in northern regions than south higher summer winter. Precipitation 1.16±7.1% 4.41±9.2% In Central Vietnam, there consistent rainfall rainy season.
