CMIP5 MACAv2-METDATA Monthly Water Balance Model Projections 1950-2099 for the Contiguous United States

We apply a monthly water-balance model (MWBM) to simulate components of the water balance for the period 1950-2099 under RCP4.5 and RCP8.5 for the Contiguous United States. We use the statistically downscaled MACAv2-METDATA temperature and precipitation data from 20 General Circulation Models (GCMs) from the Climate Model Intercomparison Program Phase 5 (CMIP5) as input to the water balance model. This dataset supports the USGS National Climate Change Viewer. The statistically downscaled dataset is: MACAv2-METDATA: Multivariate Adaptive Constructed Analogs (Abatzoglou & Brown, 2012, bias corrected by METDATA, Abatzoglou, 2013) Users interested in the downscaled temperature and precipitation files are referred to the dataset home page: MACAv2-METDATA: http://maca.northwestknowledge.net The 20 included GCMs are: bcc-csm1-1-m, bcc-csm1-1, BNU-ESM, CanESM2, CCSM4, CNRM-CM5, CSIRO-Mk3-6-0, GFDL-ESM2G, GFDL-ESM2M, HadGEM2 CC365, HadGEM2-ES365, inmcm4,IPSL-CM5A-LR, IPSL CM5A-MR, IPSL-CM5B-LR, MIROC5, MIROC-ESM, MIROC ESM CHEM, MRI-CGCM3, NorESM1-M

本研究采用月度水量平衡模型（monthly water-balance model, MWBM），针对美国本土在典型浓度路径RCP4.5与RCP8.5情景下，模拟了1950至2099年时段的水量平衡各组分。本研究以气候模式比较计划第五阶段（CMIP5）下20个通用环流模型（General Circulation Models, GCMs）产出的统计降尺度MACAv2-METDATA气温与降水数据，作为该水量平衡模型的输入驱动数据。本数据集可为美国地质调查局（USGS）国家气候变化查看器提供数据支撑。
该统计降尺度数据集为MACAv2-METDATA：基于多元自适应构造类比法（Multivariate Adaptive Constructed Analogs，Abatzoglou与Brown，2012）构建，并经METDATA完成偏差校正（Abatzoglou，2013）。
