Climate models over Southern Ocean inaccurately simulate radiation, impacting weather forecasts.
The researchers studied radiation biases over the Southern Ocean using surface-based observations and satellite data. They found that the model overestimated shortwave radiation and underestimated longwave radiation, especially in summer. Cloud properties played a significant role in these biases, with an overestimation of shortwave radiation linked to an underestimation of cloud fraction. The study suggests that improvements are needed in both the model and satellite product to better simulate radiation over the Southern Ocean.
