<p>The Integrated Multi-satellitE Retrievals for GPM (IMERG) is a NASA algorithm that merges precipitation estimates from the constellation of passive microwave satellites in the Global Precipitation Measurement (GPM) mission with microwave-calibrated infrared estimates, monthly gauge analyses, and other sources to produce a global, gridded, half-hourly precipitation record. IMERG intercalibrates, merges, and interpolates these inputs onto a 0.1 degree grid spanning the TRMM and GPM satellite eras.</p> <p>These datasets have been translated to cloud-optimized Icechunk Zarr fo...GPM集成多卫星反演产品（Integrated Multi-satellitE Retrievals for GPM，简称IMERG）是美国国家航空航天局（National Aeronautics and Space Administration, NASA）开发的算法，其将全球降水测量任务（Global Precipitation Measurement, GPM）星座中的被动微波卫星降水反演估算结果，与经微波校准的红外反演产品、地面雨量计月度分析数据及其他数据源进行融合，以生成一套全球网格化的逐半小时降水记录。IMERG会对上述输入数据开展交叉定标、融合与插值操作，将其统一映射至0.1度网格，覆盖热带降雨测量任务（Tropical Rainfall Measuring Mission, TRMM）与GPM的卫星观测周期。当前该批次数据集已被转换为云优化Icechunk Zarr格式（原文后续内容未完整呈现）。
