WRF and Eta Model Precipitation Outputs for Regional Climate Simulations over Central Amazon

This dataset contains precipitation outputs from Eta and WRF regional climate model simulations over the Central Amazon domain (Amazonas state, Brazil) for the period from December 2012 to March 2013. It includes both non-convection-permitting and convection-permitting experiments. The non-convection-permitting simulations include ETA_25km and WRF_25km, with both deep and shallow convection activated. The convection-permitting simulations include ETA_4km, ETA_3km, and WRF_4km, with deep convection deactivated and shallow convection activated. In addition, simulations with both deep and shallow convection deactivated were conducted (ETA_4km-NODSC, ETA_3km-NODSC, and WRF_4km-NODSC). ERA5 reanalysis initial and boundary conditions drove all simulations. All data files are provided in NetCDF format.本数据集包含2012年12月至2013年3月期间，针对巴西亚马逊州亚马逊中部区域开展的Eta与WRF区域气候模式模拟降水输出结果。数据集涵盖两类模拟试验：非对流容许（non-convection-permitting）试验与对流容许（convection-permitting）试验。其中非对流容许模拟包含ETA_25km与WRF_25km两组试验，均启用了深对流与浅对流参数化方案；对流容许模拟包含ETA_4km、ETA_3km与WRF_4km三组试验，均关闭深对流参数化方案，仅启用浅对流参数化方案。此外，另有同时关闭深对流与浅对流参数化方案的三组试验，分别为ETA_4km-NODSC、ETA_3km-NODSC与WRF_4km-NODSC。所有模拟均以ERA5再分析资料（ERA5 reanalysis）作为初始场与边界强迫条件，所有数据文件均采用NetCDF格式存储。
