RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations) will observe convective storms in the lee of the Andes Mountains in central Argentina during 1 November 2018 - 31 January 2019 (see NSF funded project AGS-1661799). This project will fund deployment of the Colorado State University's C-Band dualpolarization radar. The project will leverage other activities funded by NSF to staff the radar during its deployment, as well as perform post-project data quality and dissemination of the data. Data from this radar will be available to the scientific community under the RELAMPAGO data policy to address RELAMPAGO scientific objectives.Intellectual Merit:Heavy-rain producing storms will advance the science of heavy rainfall prediction globally, a risk which faces many regions of the world. Physical processes leading to deep convection and High Impact Weather (HIW) in the US rely on a specific set of ingredients that are based on weather and climate experienced there. However, the learning of deep convection and HIW outside of the US will not only improve our understanding of how it operates in other regions, but also improve our understanding of deep convection and HIW in the US. Advancing our understanding of heavy rainfall and its processes and precursors will enable improved prediction of rainfall extremes on weather and climate timescales. The C-Band radar will aid in addressing these objectives by providing high-quality dual-polarization radar measurements for a 3-month period during the RELAMPAGO intensive observing period and also following the campaign during the RELAMPAGO hydrometeorological observing period during the wet season.Broader Impacts:The exposure and vulnerability of the global population to HIW is increasing as a result of population growth, land use/land cover change, urbanization, and climate change. Severe convective storms have significant impacts on the human-managed environment around the globe. Enhancing our understanding processes capable of triggering intense, deep moist convection will help in mitigating its consequences, and is critical for social, environmental, and economic applications. Through the course of the research, significant training of graduate students, postdoctoral fellows, and close scientific interactions of the participants with Latin American scientists and students will be conducted. Local students will be given tours of the radar facility, coordinated through RELAMPAGO outreach efforts.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.

RELAMPAGO（利用自适应地面观测对电气化、闪电和中尺度/微尺度过程进行遥感）将在2018年11月1日至2019年1月31日期间观测阿根廷中部安第斯山脉背风处的对流风暴（参见 NSF 资助的项目 AGS-1661799） 。 该项目将资助科罗拉多州立大学 C 波段双极化雷达的部署。 该项目将利用美国国家科学基金会资助的其他活动，在雷达部署期间为其配备人员，并执行项目后的数据质量和数据传播。该雷达的数据将根据 RELAMPAGO 数据政策提供给科学界，以实现 RELAMPAGO 科学目标。 智力优点：产生暴雨的风暴将推动全球暴雨预测科学的发展，这是世界许多地区面临的风险。 在美国，导致深对流和高影响天气 (HIW) 的物理过程依赖于一组基于那里经历的天气和气候的特定成分。 然而，对美国以外地区的深对流和HIW的学习不仅可以提高我们对其在其他地区如何运作的了解，也可以提高我们对美国深对流和HIW的了解。 增进我们对强降雨及其过程和前兆的了解将有助于改进对天气和气候时间尺度的极端降雨的预测。 C 波段雷达将在 RELAMPAGO 密集观测期间提供为期 3 个月的高质量双偏振雷达测量，并在雨季 RELAMPAGO 水文气象观测期间跟踪活动，从而帮助实现这些目标。影响：由于人口增长、土地利用/土地覆盖变化、城市化和气候变化，全球人口对 HIW 的暴露和脆弱性正在增加。强对流风暴对全球人类管理的环境产生重大影响。增强我们对能够引发强烈、深层潮湿对流的过程的理解将有助于减轻其后果，并且对于社会、环境和经济应用至关重要。通过研究过程，将对研究生、博士后研究员进行重要培训，并让参与者与拉丁美洲科学家和学生进行密切的科学互动。 通过 RELAMPAGO 外展工作的协调，将带领当地学生参观雷达设施。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
