Analog dates for NCEP-R2 at 301 precipitation stations in Switzerland (1981-2010)

The dataset contains the results of seven variants of analog methods (AM) applied to the NCEP-R2 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 The precipitation values could not be published as they are not freely available (please contact the authors in case of interest).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)

该数据集收录了七种模拟方法（AM）在瑞士301个站点的NCEP-R2再分析结果。参数经过每日降水量的校准。本数据集旨在评估再分析对模拟方法的影响。详见参考文献以获取有关方法的更多详细信息。

数据集主要包含以下内容：所有方法和所有站点的校准参数（以文本文件形式存储）以及模拟日期（以修改后的儒略日形式存储于netCDF文件中）。由于数据并非公开可用，因此降水值未能公开发布（如有兴趣，请联系作者）。

数据集结构如下：
- 每种模拟方法（如2SLP、2Z等）的文件夹包含以下内容：
- 校准期间的模拟日期（calibration_period.zip）
- 验证期间的模拟日期（validation_period.zip）
- 用于校准的AtmoSwing（软件）输入文件（parameters_calibration_[...].xml）
- 每个站点的结果校准参数（optimized_parameters.zip）
- 降水站点的列表及其部分属性（CatalogPredictands-Precipitation-Daily-Station-Swizerland.xml）
