GPM GROUND VALIDATION NOAA S-BAND PROFILER RAW DATA NETCDF FORMAT MC3E

The GPM Ground Validation NOAA S-Band Profiler Raw Data NetCDF Format MC3E dataset was gathered during the Midlatitude Continental Convective Clouds Experiment (MC3E) in Oklahoma April 8, 2011 to June 7, 2011 and consists of uncalibrated Doppler velocity spectra data in units of relative power return. 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. The S-band 2.8 GHz profiler points vertically and measures the backscattered power from raindrops and ice particles as precipitating cloud systems pass overhead. The profiler processes radar pulses during a 7-second dwell before calculating and saving uncalibrated Doppler velocity spectra at each range gate that were separated by 60-meters vertically. Data collected during each hour are saved in two files. All precipitation mode profiles are saved in one hourly data file and all attenuated mode profiles are saved in another hourly data file. Calibrated data can be obtained from the S-band Original Dwell and Minute datasets.

GPM 地面验证项目中的 NOAA S-波段雷达剖面原始数据，采用 NetCDF 格式，MC3E 数据集，于 2011 年 4 月 8 日至 6 月 7 日在俄克拉荷马州进行的中纬度大陆性对流云实验（MC3E）期间收集。该数据集包含未经校准的多普勒速度谱数据，单位为相对功率返回。其核心目标是为对流云系统、降水及其环境提供迄今为止最完整的表征，为模型积云参数化以及陆地上的基于空间降雨检索算法提供前所未有的约束。S-波段 2.8 GHz 雷达剖面垂直指向，测量降水云系统经过头顶时雨滴和冰粒子的后向散射功率。雷达剖面在 7 秒停留期间处理雷达脉冲，并在每个距离门处计算并保存未经校准的多普勒速度谱，这些距离门在垂直方向上相隔 60 米。每小时收集的数据保存在两个文件中。所有降水模式剖面保存在一个小时数据文件中，所有衰减模式剖面保存在另一个小时数据文件中。校准数据可从 S-波段原始停留时间和分钟数据集中获得。
