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.
