Gravity field over the former Soviet Union mapped



The gravity field of our planet's largest continental land mass was virtually terra incognita for most scientists prior to the creation of a data set now available in the public domain.

Recently, the 1°×1° averaged free-air gravity anomalies over the former Soviet Union (FSU) were placed at the Bureau Gravimetrique International as an “open file” by the International Scientific Environmental Center of the Russian Academy of Sciences. The survey to develop the data set cost more than $2 billion.
