Abstract

This work provides a consistent table of the operational calibration biases of the primary ground radars in operation during the Mid Latitude Continental Convective Cloud Experiment (MC3E) in central Oklahoma. Inevitably, when operating radars small biases in the measurements get introduced from drifting performance of each of the many components that comprises the system, as well as from several different environmental variables. MC3E was a large joint campaign between the US Department of Energy and NASA consisting of many ground and airborne instruments working cooperatively to study mid latitude convective storms as part of the GPM Ground Validation field experiments. The primary ground radars have overlapping fields of view and are located nearby many other passive instruments such as disdrometers. Many of the ground radars have documented biases in their measurements that can have severe effects on derived products such as rainfall and attenuation corrected fields.
中纬度大陆对流云试验(MC3E)期间地面雷达的定标
本文提供了俄克拉荷马中部中纬度大陆对流云实验(MC3E)中主要地面雷达运行校准偏差的一致性表。不可避免的是,在操作雷达时,由于组成系统的许多组件中的每个组件的漂移性能以及几个不同的环境变量,测量结果会产生小的偏差。MC3E是美国能源部和美国国家航空航天局之间的一个大型联合项目,由许多地面和机载仪器组成,共同研究中纬度对流风暴,作为GPM地面验证现场实验的一部分。初级地面雷达具有重叠的视场,并且位于许多其他无源仪器(如分差仪)附近。许多地面雷达在测量中都有记录偏差,这可能对衍生产品(如降雨和衰减校正场)产生严重影响。
