Ground penetrating radar (GPR) has emerged as an effective tool for estimating active layer thickness (ALT) and volumetric water content (VWC) within the active layer. In August 2013, we conducted a series of GPR and probing surveys using a 500 MHz antenna and metallic probe around Barrow, Alaska. We collected about 15 km of GPR data and 1.5 km of probing data. Here, we describe the GPR data processing workflow from raw GPR data to the estimated ALT and VWC. We include the corresponding uncertainties for each measured and estimated parameter. The estimated average GPR‐derived ALT was 41 cm, with a standard deviation of 9 cm. The average probed ALT was 40 cm, with a standard deviation of 12 cm. The average GPR‐derived VWC was 0.65, with a standard deviation of 0.14.

通过在阿拉斯加的巴罗市的探地雷达测量来估算活性层厚度和体积水含量。

探地雷达(GPR)已经成为一种有效的工具,用于估算活动层内的活动层厚度(ALT)和体积水含量(VWC)。2013年8月,我们使用500 MHz天线和金属探针在阿拉斯加的巴罗(Barrow)周围进行了一系列GPR和探测调查。我们收集了大约15公里的GPR数据和1.5公里的探测数据。在这里,我们描述了从原始GPR数据到估算的ALT和VWC的GPR数据处理工作流程。我们为每个测量和估计的参数都包括了相应的不确定性。估计的平均GPR衍生ALT为41厘米,标准差为9厘米。探查的ALT平均值为40 cm,标准偏差为12 cm。GPR衍生的平均VWC为0.65,标准偏差为0.14。
