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.

这项主要的研究仪器奖是为了获得雷达系统，用于研究野火羽毛，云和降水过程。 小型雷达系统将被部署在可以由皮卡车拖曳的拖车上，从而可以在野火上收集上近距离数据。 该系统还将以固定模式使用，以收集有关沿海和山区环境中云和降水过程的数据。 更好地预测火羽行为和大气相互作用的能力将有助于告知消防员和其他急救人员，以安全地对抗火灾并做出明智的决定。 雷达系统还将用作少数派服务机构的教育工具，为学生提供动手经验。研究团队将获得KA波段双极化雷达，以研究沿海和山区的野火烟雾羽状动力学和云层的研究。 雷达将被拖车安装，并将其纳入SJSU现有的移动大气分析系统中。 当不远程部署雷达时，它将被放置在SJSU校园的屋顶天文台上。 对于野火，检索到的数据将包括均值和湍流羽状特性，灰分粒径和形状分布，以及与pyro相关云的发作有关的细节，包括在对流层上的冰形成。这些数据将大大推动野火羽流动力学的新生科学。 云研究主题将包括地形和对流提升机制以及地形云层的形成和演变。
