Resolution
Spatial aggregation: regular grid
Horizontal resolution: 0.5°x0.5°
Temporal resolution of input data: climate variables: daily
Temporal resolution of input data: co2: annual
Temporal resolution of input data: soil: constant
Input data
Observed atmospheric climate data sets used: EWEMBI
Emissions data sets used: CO2 concentration
Climate variables: sfcWind, tasmax, tas, tasmin, rlds, rsds, ps, pr
Exceptions to Protocol
Exceptions: River discharge is calculated with the CaMa-Flood v3.6 model (developed by Dai Yamazaki) which uses a different river topography compared to the DDM30 of the ISIMIP2b protocol. River network is therefore inconsistent to ISIMIP2b GHMs using the DDM30 river topography. Upstream area file is available as attachement.

Natural vegetation partition: static vegetation (5 types)
Management & Adaptation Measures
Management: No
Technological Progress
Technological progress: No
Soil
Soil layers: 4 soil layers
Routing
Runoff routing: Runoff simulated by JULES Joint UK Land Environment Simulator - version 4.7 used as input for the global river routing model CaMaFlood 3.6.2 to produce discharge.
Routing data: Routing data are described in Yamazaki, D., Kanae, S., Kim, H. and Oki, T., 2011. A physically based description of floodplain inundation dynamics in a global river routing model. Water Resources Research, 47(4). doi.org/10.1029/2010WR009726
