Bouguer gravity anomalies (acceleration, Gal)

The 2009 edition of the onshore gravity grid of Australia is a compilation of over 1.4 Million gravity stations using Bouguer gravity anomalies in galileo units of acceleration (Gal). The original resolution data (Geoscience Australia 2009) were bilinear-resampled from 400m resolution to 1km. Small areas without data were filled by neighbourhood statistics.

澳大利亚2009版陆上重力网格数据集整合了超140万个重力测点，采用加速度单位伽（Gal）的布格重力异常（Bouguer gravity anomalies）数据。该数据集的原始高分辨率数据（澳大利亚地质科学局，2009）由400米分辨率经双线性重采样处理为1公里分辨率。无有效数据的小型区域通过邻域统计法完成填充。
