A 21st century projection under SRES B1 scenario initialized in the year of the 20C_1. (EH5-T63L31_OM-GR1.5L40_B1_1)

Model: ECHM5 The atmospheric GCM ECHM5 has a spectral drnamical core where vorticity, divergence, temperature and surface pressure are represented in the horizontal by a truncated series of harmonics. A semi-Lanrangian scheme is used for the transport of water components (water vapour, cloud liquid water and cloud ice)

Scenario B1: The scenario SRES B1 describes a convergent world with the global population peaking around mid-century and declining thereafter. This scenario envisions a rapid change in economic structures toward a service and information economy, with reductions in materials and the introductionof clean and resource-efficient technologies.
