Evaluation of CMIP5 Global Climate Models over the Volta Basin: Precipitation by Jacob Agyekum, Thompson Annor, Benjamin Lamptey, Emmannuel Quansah, Richard Yao Kuma Agyeman

“…The Community Earth System Model, version 1-Biogeochemistry (CESM1-BGC), the Community Climate System Model Version 4 (CCSM4), the Max Planck Institute Earth System Model, Medium Range (MPI-ESM-MR), the Norwegian Earth System Model (NorESM1-M), and the multimodel ensemble mean were able to simulate the observed climatological mean of the annual total precipitation well (average biases of 1.9% to 7.5%) and hence were selected for the seasonal and monthly timescales. …”

Obliquity Dependence of Ocean Productivity and Atmospheric CO2 on Earth-like Worlds by Paul Lerner, Anastasia Romanou, Michael Way, Christopher Colose

“…In this study, we investigate the effects of obliquity on ocean NPP and the atmospheric CO _2 concentration using ROCKE-3D fully coupled to the NASA GISS Ocean Biogeochemistry Model. We find sea surface temperature primarily controls the NPP response, with both properties reaching a maximum at an obliquity of 45°. …”
