Free Air Anomaly 2019 - A Series

This Free Air Anomaly (FAA) grid is produced from the "A" Series grids, which were produced from a combination of ground gravity data for Australian onshore locations, gravity data derived from satellite altimetry for offshore locations, and gravity data from the EGM2008 global gravity model for the onshore locations in countries other than Australia.

本自由空气异常（Free Air Anomaly, FAA）网格由“A系列网格”生成，而“A系列网格”则通过结合三类重力数据制作而成：适用于澳大利亚陆上区域的地面重力数据、适用于近海区域的卫星测高衍生重力数据，以及适用于澳大利亚以外国家陆上区域的EGM2008全球重力模型重力数据。
