Analog dates for ERA-20C at 301 precipitation stations in Switzerland (1981-2010)

The dataset contains the results of seven variants of analog methods (AM) applied to the ERA-20C reanalysis at 301 stations in Switzerland. The parameters were calibrated for daily precipitation. This dataset is part of an assessment of the impact of the reanalyses on AMs. See the reference for more details on the methods. The dataset principally consists in the calibrated parameters (in text files) for all methods and all stations as well as the analog dates (as Modified Julian Dates) in netCDF files. The precipitation values could not be published as they are not freely available (please contact the authors in case of interest). The dataset structure is: - A folder for every analog method (2SLP, 2Z, …) containing: - The analog dates for the calibration period (calibration_period.zip) - The analog dates for the validation period (validation_period.zip) - The input files used by AtmoSwing (the software) for the calibration (parameters_calibration_[...].xml) - The resulting calibrated parameters for every station (optimized_parameters.zip) - The list of the precipitation stations with some of their properties (CatalogPredictands-Precipitation-Daily-Station-Swizerland.xml)本数据集包含七种类比方法（Analog Methods，AM）变体针对瑞士301个站点的ERA-20C再分析数据的应用结果。研究针对日降水参数完成校准。本数据集是评估再分析数据对类比方法影响的相关研究的一部分，相关方法的详细信息请参阅参考文献。 本数据集主要包含两类内容：一是所有方法与所有站点的校准参数（存储于文本文件中），二是netCDF格式文件中的类比日期（采用修正儒略日（Modified Julian Date）标注）。由于降水数据无法免费公开，因此本数据集未包含降水数值，如有获取需求，请联系作者。 数据集的组织结构如下： - 每个类比方法（如2SLP、2Z等）对应一个独立文件夹，文件夹内包含： 1. 校准期的类比日期压缩文件（calibration_period.zip） 2. 验证期的类比日期压缩文件（validation_period.zip） 3. AtmoSwing软件用于校准的输入配置文件（parameters_calibration_[...].xml） 4. 各站点的最终优化校准参数压缩文件（optimized_parameters.zip） 5. 瑞士每日降水站点列表及其部分属性信息文件（CatalogPredictands-Precipitation-Daily-Station-Swizerland.xml）
