MRI: Acquisition of a Multi-purpose Cloud Radar

这一重大研究仪器奖是为了奖励为研究野火羽流以及云和降水过程而购买的雷达系统。这种小型雷达系统将部署在一辆拖车上，可以被皮卡车拖走，从而可以近距离收集野火数据。该系统还将以固定模式使用，收集沿海和山区环境中的云和降水过程的数据。更好地预测火灾羽流行为和火灾-大气相互作用的能力将有助于为消防员和其他紧急人员提供信息，帮助他们安全扑火并做出明智的决策。该雷达系统还将作为少数民族服务机构的教育工具，为学生提供实践体验。研究小组将获得一台Ka波段双极化雷达，用于研究野火烟羽动力学以及沿海和山区的云和降水。该雷达将安装在拖车上，并纳入上海州立大学现有的移动大气剖面系统。当雷达没有被远程部署时，它将被放置在上海州立大学校园的屋顶天文台。对于野火，检索的数据将包括平均和湍流烟羽特性、火山灰颗粒大小和形状分布，以及与火热对流云开始有关的细节，包括对流层上部的冰形成。这些数据将极大地推动野火羽流动力学这门新兴科学的发展。云的研究主题将包括地形和对流抬升机制以及地形卷云的形成和演变。

This Major Research Instrumentation award is for the acquisition of a radar system for the study of wildfire plumes and cloud and precipitation processes. The small radar system will be deployable on a trailer that can be towed by a pickup truck, allowing for up-close data collection on wildfires. The system will also be used in a stationary mode to collect data on cloud and precipitation processes in coastal and mountainous environments. The ability to better predict fire plume behavior and fire-atmosphere interactions will help to inform fire fighters and other emergency personnel in their efforts to fight fire safely and make informed decisions. The radar system will also be used as an educational tool at a Minority Serving Institution, providing hands-on experience to students.The research team will acquire a Ka-band dual-polarization radar for studies of wildfire smoke plume dynamics and clouds and precipitation in coastal and mountainous regions. The radar will be trailer-mounted and incorporated into SJSU's existing mobile atmospheric profiling system. When the radar is not remotely deployed, it will be placed at a rooftop observatory on the SJSU campus. For wildfires, the retrieved data will include mean and turbulent plume properties, ash particle size and shape distributions, and details pertaining to the onset of pyro-convective clouds, including the formation of ice in the upper troposphere. These data will significantly advance the nascent science of wildfire plume dynamics. Cloud study topics will include orographic and convective lifting mechanism and the formation and evolution of orographic cirrus clouds.
