Gravity Anomaly Grid of the Australian Region - 2010

This grid represents gravity anomalies of the Australian region. The grid combines accurate onshore gravity measurements, with satellite data over the offshore region. The cell values represent simple Bouguer anomalies at a density of 2.67 tonnes per cubic metre onshore and free-air anomalies offshore. The grid cell size is 0.5 minutes of arc, which is equivalent to about 800 metres.

本网格数据集呈现澳大利亚区域的重力异常分布。该数据集整合了高精度的陆上重力实测数据与近海区域的卫星观测数据。网格单元的数值对应两类重力异常：陆上区域以2.67吨/立方米的密度计算得到的简易布格重力异常（simple Bouguer anomalies），近海区域则为自由空气重力异常（free-air anomalies）。该网格的单元尺寸为0.5角分，约合800米。
