Multi-model ensemble of regional reanalyses over Italy - Hourly precipitation
收藏资源简介:
This dataset contains the multi-model ensemble mean of hourly precipitation fields of four high-resolution regional-reanalysis products recently developed over Italy by dynamically downscaling the global reanalysis ERA5 with different convection-permitting numerical models: MERIDA_HRES (Viterbo et al., 2024) MOLOCH (Capecchi et al., 2023) SPHERA (Giordani et al., 2023) VHR-REA_IT (Adinolfi et al., 2023) Before the ensemble aggregation, the individual reanalysis fields have been pre-processed through a re-projection over a common regular latitude-longitude grid with a grid spacing of 3 km, and retaining only the grid points over the Italian territory. This dataset is currently available for the period December 2006 - November 2016.
本数据集包含四款近期针对意大利区域研发的高分辨率区域再分析产品的多模式集合平均逐小时降水场。上述产品均通过不同对流允许数值模式,对全球再分析资料ERA5开展动力降尺度构建而成。 四款参与集合的产品分别为: MERIDA_HRES(Viterbo等,2024) MOLOCH(Capecchi等,2023) SPHERA(Giordani等,2023) VHR-REA_IT(Adinolfi等,2023) 在进行集合平均计算前,已对各单份再分析场完成预处理:先将其重投影至网格间距为3 km的统一规则经纬网格,且仅保留意大利境内的格点数据。本数据集当前的可用时段为2006年12月至2016年11月。
