Accurate and high-resolution data reflecting different climate scenarios are vital for policy makers when deciding on the development of future energy resources, electrical infrastructure, transportation networks, agriculture, and many other societally important systems. However, state-of-the-art long-term global climate simulations are unable to resolve the spatiotemporal characteristics necessary for resource assessment or operational planning. We introduce an adversarial deep learning approach to super resolve wind velocity and solar irradiance outputs from global climate models to scales sufficient for renewable energy resource assessment. Using adversarial training to improve the physical and perceptual performance of our networks, we demonstrate up to a [Formula: see text] resolution enhancement of wind and solar data. In validation studies, the inferred fields are robust to input noise, possess the correct small-scale properties of atmospheric turbulent flow and solar irradiance, and retain consistency at large scales with coarse data. An additional advantage of our fully convolutional architecture is that it allows for training on small domains and evaluation on arbitrarily-sized inputs, including global scale. We conclude with a super-resolution study of renewable energy resources based on climate scenario data from the Intergovernmental Panel on Climate Change's Fifth Assessment Report.
准确且高分辨率的数据能反映不同气候情景,这对于政策制定者在决定未来能源资源、电力基础设施、交通网络、农业以及许多其他对社会至关重要的系统的发展时至关重要。然而,当前最先进的长期全球气候模拟无法解析资源评估或运营规划所需的时空特征。我们引入一种对抗性深度学习方法,将全球气候模型的风速和太阳辐照度输出超分辨率提升至足以进行可再生能源资源评估的尺度。通过对抗训练来提高我们网络的物理和感知性能,我们展示了风速和太阳能数据分辨率提高了高达[公式:见正文]。在验证研究中,推断出的场对输入噪声具有鲁棒性,具有大气湍流和太阳辐照度正确的小尺度属性,并且在大尺度上与粗数据保持一致。我们的全卷积架构的另一个优点是它允许在小区域上进行训练,并对任意大小的输入进行评估,包括全球尺度。我们基于政府间气候变化专门委员会第五次评估报告的气候情景数据,对可再生能源资源进行了超分辨率研究并得出结论。
