Surface mass balance in the last three centuries derived from microwave radar data collected in the Dome Fuji region

This dataset presents two-way travel time and corresponding depths of three reflectors extracted from microwave radar data and dated using a firn core in the vicinity of Dome Fuji, inland East Antarctica. These reflectors are in the top ~15 m of the firn, and dated 1941, 1923, and 1755 CE. Surface mass balance averaged between these years to 2019 is also presented. Radar data were collected at ~1.1 m intervals over ~1100 km in about 500 km2, which resulted in about 1 million data points. At each of radar data points, surface slope over 200 m horizontal distance is calculated using Reference Elevation Model of Antarctica (REMA) and ICESat-2 altimetry data, which are also included in this dataset.
