Coupled ocean-atmosphere climate models suffer from a number of climatological biases in sea surface temperature (SST) such as the cold tongue bias in the tropical Pacific, and warm biases along eastern subtropical ocean boundaries (e.g. Zheng et al. 2011; Erfani and Burls, 2019). Here, we investigate the possibility of reducing these biases within both low and high-resolution versions of a fully coupled climate model (CESM) by globally (and regionally) correcting the net shortwave (SW()*) flux at the surface towards values derived from Clouds and Earth's Radiant Energy Systems (CERES)-Energy Balanced And Filled (EBAF) climatological estimates
