cops_nsod_ubt: wind data from sodar-RASS run by University of Bayreuth during COPS 2007

Project: Convective and Orographically-induced Precipitation Study - Weather forecast models have not been successful in improving the Quantitative Precipitation Forecast during the last 16 years. One reason for this stagnation is the lack of comprehensive, high-quality data sets usable for model validation as well as for data assimilation, thus leading to improved initial fields in numerical models. Theoretical analyses have identified the requirements measured data have to meet in order to close the gaps in process understanding. In field campaigns, it has been shown that the newest generation of remote sensing systems has the potential to yield data sets of the required quality. It is therefore time to combine the most powerful remote sensing instruments with proven ground-based and airborne measurement techniques in an Intensive Observations Period (IOP). Its goal is to serve as a backbone for the Priority Program SPP 1167 by producing the demanded data sets of unachieved accuracy and resolution. This requires a sophisticated scientific preparation and a careful coordination between the efforts of the institutions involved. For the first time, the pre-convective environment, the formation of clouds and the onset and development of precipitation as well as its intensity will be observed in four dimensions simultaneously in a region of sufficient size. This shall be achieved by combining the IOP with international programs and by collaboration between leading scientists in Europe, US, and other countries. Thus, the IOP, which we call Convective and Orographically-induced Precipitation Study (COPS), is a unique opportunity for an international field campaign featuring the newest generation of measurement systems such as scanning radar and lidar and leading to outstanding advances in atmospheric sciences. Please be aware of the common COPS/GOP/D-PHASE data policy, which you please find at http://cops.wdc-climate.de/ Summary: The Sodar/RASS device installed at Fussbach consisted of a DSDPA.90/64-Sodar and a DSDR3x7-1290MHz-RASS extension by METEK GmbH. It operated with an averaging period of 10 min. The minimum measurement height was 40 m and the maximum measurement height 700 m with a step width of 20 m in between.

项目：对流与地形诱发降水研究（Convective and Orographically-induced Precipitation Study, COPS）
过去16年间，天气预报模型在定量降水预报（Quantitative Precipitation Forecast, QPF）领域始终未能实现突破性进展。造成这一停滞局面的核心原因之一，便是缺乏可用于模型验证与数据同化的高质量综合数据集，进而无法有效改善数值模型的初始场条件。理论分析已明确了实测数据需满足的核心要求，以填补当前对相关物理过程认知的空白。野外试验研究表明，新一代遥感系统具备获取符合质量要求数据的潜力。因此，当前亟需将最先进的遥感仪器与成熟的地基、机载测量技术相结合，开展密集观测期（Intensive Observations Period, IOP）工作。该观测期的核心目标是作为优先项目SPP 1167（Priority Program SPP 1167）的核心支撑框架，生成精度与分辨率均达到前所未有的所需数据集。这一工作需要周密的科学筹备，以及所有参与机构间的细致协调配合。本次研究将首次在足够大的区域范围内，以四维同步观测的方式，对对流前环境、云系形成、降水的发生与发展过程及其强度进行全维度监测。这一目标将通过将密集观测期与国际研究计划相结合，并联合欧洲、美国及其他国家的顶尖科研人员开展协作来实现。我们将此次密集观测期命名为对流与地形诱发降水研究（COPS），它为国际野外试验提供了独一无二的契机，可搭载新一代测量系统（如扫描雷达与激光雷达），进而推动大气科学领域取得卓越进展。请注意遵循通用的COPS/GOP/D-PHASE数据政策，详情可查阅http://cops.wdc-climate.de/
