General Observation Period of Priority Programm on Quantitative Precipitation Forecasting

The main goal of the General Observation Period (GOP) within the Priority Programm on Quantitative Precipitation Forecasting is to gather a comprehensive data set suitable for testing hypotheses and new modeling techniques developed within PQP. The GOP encompasses the Convectively and Orographically induced Precipitation Study COPS performed in south-west Germany in summer 2007 both in time and space to provide information of all kinds of precipitation types and to relate the COPS results to a broader perspective (longer time series and larger spatial domain). The duration of one year will open up the possibility to statistically approach model problems and better pin down specific model weaknesses: Some problems e.g. initial and boundary conditions might cancel out when longer time series are considered. The GOP will therefore provide a basis for reaching the PQP goal: Determination and use of the potentials of existing and new data as well as process descriptions to improve QPF.

本项定量降水预报优先计划（PQP）中的通用观测期（GOP）的主要目标在于收集一套全面的数据集，以供测试在PQP框架下开发出的假设与新型建模技术。该观测期包括在2007年夏季于德国西南部进行的对流性和地形性诱发降水研究（COPS），旨在时空维度上提供各类降水类型的信息，并将COPS的研究成果与更广泛的视角（更长的时序和更大的空间范围）相联系。一年的观测周期将有助于从统计学的角度探讨模型问题，并更精确地锁定特定的模型弱点：例如，在某些情况下，如初始条件和边界条件，当考虑更长时间序列时可能会相互抵消。因此，GOP将为实现PQP的目标提供基础：确定并利用现有和新数据以及过程描述的潜力，以提升定量降水预报（QPF）的准确性。请留意常见的COPS/GOP/D-PHASE数据政策，具体信息请查阅http://cops.wdc-climate.de/。
