What is the gradient of gravity

The vertical gradient of gravity, which is the derivative of gravity along the plumb line, is also known as the second-order derivative of the gravitational potential, Wzz (or gz), and represents the rate of change of the gravity field strength, g, in the vertical direction. It can reflect local anomalies more sensitively.

Gravity vertical gradient measurement plays an important role in geophysical exploration. It is especially important to quickly and accurately calculate the value of gravity vertical gradient through measurement experiments.

Currently there are two methods of determining the vertical gradient of gravity: the traditional method of measurement, synchronous observation method.

The measurement of gravity and its gradient is an extremely precise measurement work, which must be operated very carefully. In order to obtain this information in high quality, there are even many experts or professors abroad who personally operate these instruments.
