GPM GROUND VALIDATION NASA S-BAND DUAL POLARIMETRIC (NPOL) DOPPLER RADAR IFLOODS

The GPM Ground Validation NASA S-Band Dual Polarimetric (NPOL) Doppler Radar IFloodS dataset was collected from April 30 to June 16, 2013 near Traer, Iowa as part of the Global Precipitation Measurement (GPM) mission Iowa Flood Studies (IFloodS) campaign. Officially the IFloodS campaign ran from May 1 to June 15 but the NPOL Doppler radar was installed and calibrated prior to the start, allowing for the wider period of record. The NPOL radar, developed by a research team from Wallops Flight Facility, is a fully transportable and self-contained S-band (10 cm), scanning dual-polarimetric, doppler research radar that collected and operated nearly continuously during the IFloodS field campaign. It takes accurate volumetric measurements of precipitation including rainfall rate, particle size distributions, water content and precipitation type. The NPOL Doppler Radar IFloodS data is available in Universal Format (UF) with browse images available in PNG file format.

GPM 地面验证项目之 NASA S-波段双极化（NPOL）多普勒雷达 IFloodS 数据集，于 2013 年 4 月 30 日至 6 月 16 日期间在爱荷华州特拉尔附近收集，作为全球降水测量（GPM）任务爱荷华洪水研究（IFloodS）活动的一部分。正式而言，IFloodS 活动自 5 月 1 日至 6 月 15 日运行，但 NPOL 多普勒雷达在活动开始前已安装并校准，从而允许更广泛的记录期。NPOL 雷达由沃尔lops 飞行设施的研究团队开发，是一种完全可移动且自给自足的 S 波段（10 厘米）扫描双极化、多普勒研究雷达，在 IFloodS 野外研究活动中几乎连续收集和运行。该雷达能够精确测量降水体积，包括降雨速率、粒子尺寸分布、含水量和降水类型。NPOL 多普勒雷达 IFloodS 数据以通用格式（UF）提供，并附有可供浏览的 PNG 格式图片。
