GPM GROUND VALIDATION CHILL RADAR MC3E V1

The GPM Ground Validation CHILL Radar MC3E dataset was collected during the Midlatitude Continental Convective Clouds Experiment (MC3E), which was held in Oklahoma were collected while the NASA ER-2 aircraft conducted a series of four legs along the 090 and 120 degree CHILL azimuths on May 24, 2011. Dual linear polarization variables as well as Doppler velocity, radial velocity, and normalized coherent power are contained in this dataset. In an effort to expand the MC3E sampling to a wider geographical area, the NASA ER-2 aircraft was directed to Northeastern Colorado while widespread rain was in progress on May 24, 2011. The aircraft flew a series of pre-defined ground tracks that coincided with radials from the CSU-CHILL radar. This aided in keeping the aircraft in the plane of a series of RHI scans done by CSU-CHILL. The single polarization CSU-Pawnee radar maintained volume coverage of the echo system while the radial flight legs were in progress. During aircraft course reversals at the ends of the radial legs, the CHILL and Pawnee radars started volume scans in synchronization to support dual Doppler wind syntheses. The Pawnee radar data are available as a seperate dataset.

GPM 地面验证 CHILL 雷达 MC3E 数据集是在中纬度大陆性对流云实验（MC3E）期间收集的，该实验于2011年5月24日在俄克拉荷马州举行。在此期间，NASA ER-2 飞机沿090度和120度CHILL方位角执行了四次飞行段。该数据集包含双线性极化变量、多普勒速度、径向速度和归一化相干功率。为了将MC3E的采样范围扩展到更广阔的地理区域，NASA ER-2 飞机于2011年5月24日当广泛降雨进行时被指引至科罗拉多东北部。飞机按照预定义的地面轨迹飞行，这些轨迹与CSU-CHILL雷达的径向线相吻合。这有助于将飞机保持在CSU-CHILL执行的一系列RHI扫描的平面上。在径向飞行段的末端进行飞机航线反转时，CHILL和Pawnee雷达同步启动体积扫描，以支持双多普勒风速合成。Pawnee雷达数据作为独立的数据集提供。
