The Center for Severe Weather Research (CSWR) proposes to continue providing three mobile Doppler radars known as Doppler on Wheels (DOWs) as part of the national Lower Atmosphere Observing Facility (LAOF) suite. The CSWR DOWs fulfill an important role in the suite of NSF-supported lower atmosphere observing facilities by providing a low-cost, nimble technology for obtaining critical measurements at close-range to severe weather. Users of the DOWs have conducted research into topics such as tornado genesis, winter storm development, winds associated with hurricane landfall, and in-cloud microphysical processes. The DOWs are state-of-the-art X-band radars mounted on purpose-built trucks to provide rapid access to weather phenomena of interest. The facility consists of two dual-polarimetric X-band radars (DOWs 6 and 7) and one multi-beam X-band (Rapid-Scan DOW) that provides very fast, high spatial resolution data. During the next performance period (2014-2018), CSWR will deploy the DOWs, as well as their Mesonet vehicles (truck-mounted mobile weather stations) and "tornado pods", a collection of ruggedized, deployable, instrumented structures designed to measure meteorological variables during encounters with extreme weather, in support of research projects deemed to be of exceptional merit by the peer review process. CSWR staff will maintain and upgrade the instrumentation to facilitate cutting edge research in the areas of atmospheric dynamics and cloud physics. Future deployments will be augmented by the availability of the mobile mesonet sampling capability. CSWR will apply the latest technologies in their radars in accord with community research needs and plan to develop new mobile capabilities such as a mobile C-band radar.Over the past five years, the DOWs have been the most requested lower atmosphere observing facility for educational and outreach purposes. Since 2008, the DOWs and CSWR staff have deployed to eighteen universities across the United States and have carried out extensive "on-the-road" tours involving public displays and lectures that have reached over 100,000 members of the general public. CSWR expects to continue providing these services as requested and has among its staff two credentialed teachers (one in elementary education and another in high school science) who bring age-appropriate pedagogy to the outreach events.

恶劣天气研究中心(CSWR)建议继续提供三个被称为轮上多普勒(DOW)的移动多普勒雷达，作为国家低层大气观测设施(LAOF)套件的一部分。CSWR DOW在NSF支持的低层大气观测设备套件中发挥着重要作用，它提供了一种低成本、灵活的技术，可以在近距离或恶劣天气下获得关键测量结果。DOW的用户已经对龙卷风的成因、冬季风暴的发展、与飓风登陆相关的风以及云中微物理过程等主题进行了研究。DOW是安装在专门制造的卡车上的最先进的X波段雷达，提供对感兴趣的天气现象的快速访问。该设施包括两个双极化X波段雷达(DOW 6和7)和一个多波束X波段(快速扫描DOW)，它提供非常快的高空间分辨率数据。在下一个业务期(2014-2018年)，CSWR将部署DOW以及它们的Mesonet车辆(车载移动气象站)和“龙卷风吊舱”，这是一组坚固的、可部署的仪表化结构，旨在测量遇到极端天气时的气象变量，以支持同行审查进程认为具有特殊价值的研究项目。CSWR工作人员将维护和升级仪器，以促进大气动力学和云物理领域的尖端研究。未来的部署将通过移动中间网采样能力的提供而得到加强。CSWR将根据社区研究需要在其雷达中应用最新技术，并计划开发新的移动能力，如移动C波段雷达。在过去五年中，DOW一直是用于教育和推广目的的最受欢迎的低层大气观测设施。自2008年以来，DOW和CSWR的工作人员已被部署到全美18所大学，并开展了广泛的“巡回”旅行，包括公开展示和讲座，已惠及超过10万名普通公众。CSWR预计将按要求继续提供这些服务，其工作人员中有两名有资格证书的教师(一名是初等教育教师，另一名是高中科学教师)，他们把适合年龄的教学方法带到外联活动中。
