Short summary
We developed a new method to estimate how much heat the ocean surface receives from the atmosphere, which is important for understanding weather and climate. Using over 30 years of data from buoys around the world, we created a model that outperforms existing ones, especially under cloudy skies. Our results show that including detailed cloud information improves accuracy, making this method useful for global climate and ocean research.
