RECON - Cell-scale atmospheric moisture flows dataset reconciled with ERA5 reanalysis

The RECON dataset provides moisture flow volumes, in cubic meters, from evaporation sources to precipitation targets and vice versa. It offers global coverage at a resolution of 0.5° for an average year based on the period 2008–2017. It is a post-processed version of the Lagrangian (forward trajectory-based) tracking model UTrack dataset (DOI UTrack dataset: 10.1594/PANGAEA.912710, DOI Utrack support paper: 10.5194/essd-12-3177-2020), by means of Iterative Proportional Fitting procedure and ERA5 preprocessing.Data are stored in integers that need to be transformed into cubic meters, as explained in the supplement material pdf file. More information on the generation of the dataset, authors of the dataset, input variable information and data extraction with simple python scripts are provided in our official GitHub repository. We provide the following files: RECON_moisture_flows_0.5.nc.7z: is a compressed/packed version of the NetCDF4 RECON dataset. To get the NetCDF dataset file, follow the instructions in the supplement guide (RECON_supplementary_guide.pdf) ERA5_m_0.5_volumes_corrected.nc where m is the month: our own edited version of monthly averaged ERA5 data, that have been used to retrieve moisture volume flows from the Utrack dataset, as explained in our official GitHub repository RECON_ERA5_avgYear_0.5_volumes.nc: our own edited version of yearly averaged ERA5 data, that have been used to postprocess moisture volume flows retrieved from the UTrack dataset in order to get the RECON dataset, as explained in our official GitHub repository By sharing these ERA5 files, we provide means for reproducibility of our postprocessing framework.RECON数据集提供以立方米为单位的水汽体积输送量，涵盖从蒸发源至降水目标的输送过程，且包含反向输送。该数据集实现全球覆盖，空间分辨率为0.5°，数据基于2008-2017年时段的多年平均年尺度。本数据集是对基于拉格朗日（Lagrangian）正轨迹追踪的UTrack数据集进行后处理得到的版本，后处理流程采用迭代比例拟合（Iterative Proportional Fitting）方法与ERA5预处理步骤。数据以整数格式存储，需按照补充材料PDF文件中的说明转换为立方米单位。有关该数据集的生成方法、作者信息、输入变量说明以及使用简易Python脚本提取数据的详细内容，均可在我们的官方GitHub仓库中查阅。 本次共享的文件包括： 1. RECON_moisture_flows_0.5.nc.7z：RECON数据集NetCDF4格式文件的压缩包。如需获取原始NetCDF数据集文件，请参照补充指南（RECON_supplementary_guide.pdf）中的操作说明。 2. ERA5_m_0.5_volumes_corrected.nc（其中m代表月份）：我们自行编辑的月平均ERA5数据版本，该数据用于从UTrack数据集中提取水汽体积通量，具体方法详见我们的官方GitHub仓库。 3. RECON_ERA5_avgYear_0.5_volumes.nc：我们自行编辑的年平均ERA5数据版本，该数据用于对从UTrack数据集中提取的水汽体积通量进行后处理，以生成RECON数据集，具体方法详见我们的官方GitHub仓库。 本次共享上述ERA5相关文件，旨在为复现我们的后处理流程提供支撑。
