The Dome A region directly receives sedimentation from the Earth's stratosphere atmosphere, where the ice sheet is formed by primitive accumulation and stores global climate and atmospheric environmental information. The Dome A region is also the central area of the Antarctic cold source, which is expected to obtain the lowest temperature on the Earth's surface. It is the most important driving source in the Earth's climate and environmental dynamics system and the most ideal area for modern Earth's climate and environmental dynamics background observation. This dataset represents the accumulation rate distribution of the inland ice cover survey route from Zhongshan Station to DomeA, Antarctica, China
Accumulation rate within a range of 100km (50km on both sides) along the inland ice cover inspection route from Zhongshan Station to Dome A. It is obtained from the cumulative rate data of Antarctic ice sheet surface area compiled by David Waughan and Mario Giovinetto
After interpolation, ESRI grid and text format data with resolution of 1km and 5km are output. Dome A is located in the center of the South East pole, which is the highest point of the Antarctic ice sheet that has not been scientifically explored.
This instrument belongs to the routine observation project, the observation environment is basically suitable, and the data quality is high.
