To achieve complete renewable-based electrification from the current level of less than 20% globally presents great challenges for the energy science community. This requires hundreds of trillions of kilowatt-hours of renewable energy, mainly generated through wind and solar power. One neglected but crucial question is whether extracting such huge amount of energy from the atmosphere's surface layer would alter the atmosphere's physics, leading to new climate change challenges. This CAREER project will focus on addressing whether large-scale solar photovoltaic plants alter the local climate. The research will parameterize the atmospheric response carried out by transport processes to facilitate the inclusion of solar plants in climate models. This project will pave the way for undergraduate and graduate students in middle Tennessee to become engaged in climate change education and discussion. The results of this research will enable a new "Atmospheric Transport" course at Tennessee Technological University, a textbook titled Atmospheric Transport to increase scientific literacy, and an educational mobile app ATMOSPort.This project seeks to study the interactions between the near-ground atmosphere and an artificial canopy of millions of solar photovoltaic panels. A two-stage field campaign and computational fluid dynamics simulations are proposed to provide an understanding of thermal transport dynamics within the atmospheric boundary layer above thousands of acres of dark, hot, tall, and rough Photovoltaic panels of utility-scale solar plants. The knowledge gained will clarify whether such giant canopies alter the local climate and will lead to the creation of equations that accurately describe the affected atmospheric characteristics. The proposed research quantifies the significance of these impacts for various background surface conditions and parameterizes the thermal and mechanical effects of the plant to allow meteorologists and environmental engineers to incorporate them into their models efficiently. This achievement would increase the accuracy of atmospheric simulations within regions where utility-scale photovoltaic plants exist.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

为了从当前少于20％的全球水平上实现完全基于可再生能源的电气化，对能源科学界面临着巨大的挑战。这需要数百万亿千瓦时的可再生能源，主要是通过风能和太阳能产生的。一个被忽视但至关重要的问题是，从大气的表面层中提取如此庞大的能量是否会改变大气的物理学，从而导致新的气候变化挑战。该职业项目将着重于解决大型太阳能光伏电厂是否改变了当地气候。这项研究将通过运输过程进行参数化大气反应，以促进在气候模型中纳入太阳能。该项目将为田纳西州中部的本科生和研究生铺平道路，以参与气候变化教育和讨论。这项研究的结果将在田纳西技术大学（Tennessee Technological University）进行新的“大气运输”课程，这是一本名为“大气传输”的教科书，以提高科学素养，并提供了一个教育的移动应用AptoSport。该项目旨在研究近地大气和数百万个Solar Photar Photar Photar photoRAr Photovoltaic Panels的人造冠层之间的相互作用。提出了一个两阶段的现场运动和计算流体动力学模拟，以提供对大气边界层内数千英亩的深色，热，高和粗糙光伏的太阳能电厂的高度传输动力学的理解。获得的知识将阐明这种巨大的檐篷是否改变了当地的气候，并将导致创建准确描述受影响大气特征的方程式。拟议的研究量化了这些影响对各种背景条件条件的重要性，并参数化了工厂的热和机械效应，以使气象学家和环境工程师有效地将它们纳入其模型中。这项成就将提高存在公用事业尺度光伏植物的区域内大气模拟的准确性。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，认为值得通过评估来获得支持。
