GPM GROUND VALIDATION NASA S-BAND DUAL POLARIMETRIC (NPOL) DOPPLER RADAR MC3E

The GPM Ground Validation NASA S-band Dual Polarimetric (NPOL) Doppler Radar MC3E dataset was collected by the NASA NPOL radar, which was 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 data nearly continuously during the Midlatitude Continental Convective Clouds Experiment (MC3E) field campaign. The overarching goal was to provide the most complete characterization of convective cloud systems, precipitation, and the environment that has ever been obtained, providing constraints for model cumulus parameterizations and space-based rainfall retrieval algorithms over land that had never before been available. NPOL scanned in high resolution Range Height Indicator (RHI) mode (every 40 sec) and provided measurements of precipitation in liquid, mixed and ice phase. The scanning strategy emphasized vertical structure sampling via RHI and narrow sector-volume data collections. Additional files were processed from the UF files using the Colorado State University (CSU) Hydrometeor Identification Algorithm (HID) providing classification of hydrometeors (e.g. rain, drizzle, hail, ice crystals, wet or dry snow, graupel density). Data was collected from April 11, 2011 through June 3, 2011.

该GPM地面验证NASA S波段双偏振（NPOL）多普勒雷达MC3E数据集由NASA NPOL雷达收集，该雷达由沃尔lops飞行设施的研究团队开发，是一款完全可携带和自给自足的S波段（10厘米）扫描双偏振、多普勒研究雷达。该雷达在Midlatitude Continental Convective Clouds Experiment（MC3E）现场试验期间近乎连续地收集了数据。其总体目标是提供迄今为止对对流云系统、降水及其环境的最为详尽的表征，为模型积云参数化和陆基降水提取算法提供前所未有的约束。NPOL采用高分辨率范围高度指示器（RHI）模式（每40秒一次）进行扫描，并提供了液体、混合和冰相降水的测量数据。扫描策略强调了通过RHI和窄扇区体积数据收集进行垂直结构采样。此外，通过使用科罗拉多州立大学（CSU）的水文粒子识别算法（HID）从UF文件中处理了额外的文件，提供了对水文粒子（例如雨、毛毛雨、冰雹、冰晶、湿雪或干雪、霰密度）的分类。数据收集时间从2011年4月11日至2011年6月3日。
