GCIP/ESOP-97: NCRFC WSR-88D Stage III Hourly Precipitation Imagery. Version 1.0

This data set contains data from the NOAA North Central River Forecast Center (NCRFC). The NCRFC routinely ingests WSR-88D precipitation derived products (Level III) from each of the radar sites with coverage in the Upper Mississippi River Basin. In addition the NCRFC ingests real-time precipitation data from several hundred gages. The NCRFC produces a number of derived or "Stage" products using the radar and precipitation gage data. A Stage II product is produced by merging radar precipitation estimates (Stage I) with ground truth data provided by the gages. The Stage II estimates are then composited into a Stage III precipitation 4 x 4 km resolution area averaged mosaic for the Upper Mississippi River Basin.

本数据集包含美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）北中河流预报中心（North Central River Forecast Center, NCRFC）的相关数据。该中心常规接收覆盖密西西比河上游流域的各雷达站点产出的WSR-88D降水衍生产品（Level III级）。此外，该中心还接收来自数百个雨量计的实时降水数据。该中心依托雷达与雨量计数据，生成多款‘Stage’系列衍生产品。其中，Stage II级产品通过将雷达降水估算结果（Stage I级）与雨量计提供的地面实测数据融合制成。随后，Stage II级估算结果将被合成为适用于密西西比河上游流域的Stage III级降水镶嵌图，其分辨率为4×4公里，采用区域平均法生成。
