*2.3. CRU/CRUNCEP*

We used 0.5 × 0.5 degree monthly temperature and precipitation from Climate Research Unit (CRU-TS3.23) and solar radiation data from CRU National Centers for Environmental Prediction version 4 (CRUNCEP-V4, a blend of CRU data and NCEP- National Center for Atmospheric Research (NCAR) reanalysis data) [25]. CRU data are interpolated gridded datasets from monthly observations. To be consistent with historical CMIP5 runs, we used CRU/CRUNCEP data from overlapping the period with Global Inventory Modeling and Mapping Studies (GIMMS)-LAI data during 1982–2005.
