Downward continuation is a key step in processing airborne geomagnetic data. However, downward continuation is a typically ill-posed problem because its computation is unstable; thus, regularization methods are needed to realize effective continuation ...

Far-zone contributions of airborne gravity anomalies' upward/downward continuation
Airborne gravimetry has become a vital technique in local gravity field approximation, and upward/downward continuation of gravity data is a key process of airborne gravimetry.

Study on the stable and high-precision downward extension method of airborne gravity anomaly data [PDF]
The essence of the downward continuation of airborne gravity anomalies is to solve the first kind of Fredholm integral equation, which is an ill-posed problem. Stable and high-precision downward continuation methods have always been a research hotspot in

A Recursive Truncated Taylor Expansion Downward Continuation Method for Geomagnetic Field
In aeromagnetic detection and geomagnetic navigation, the reference geomagnetic maps usually need to be continued to different altitudes. Traditionally, the geomagnetic field upward continuation is stable.

The downward continuation of the disturbing potential based on poisson's integral
En este artículo se prueban y valoran dos métodos diferentes para la realización de la continuación descendente de potencial perturbante. La importancia del potencial perturbante en geodesia reside en que éste es fundamental en la determinación del ...

Harmonic downward continuation of gravity anomalies
The question we would like to address is: Can any of the gravity anomalies (free-air, Fay, Bouguer, Helmert, etc.), multiplied by the radius r, be continued downward, using the (only rigorous) Poisson approach?

Upward and downward statistical continuities [PDF]
A real valued function f defined on a subset E of R, the set of real numbers, is statistically upward (resp. downward) continuous if it preserves statistically upward (resp. downward) half quasi-Cauchy sequences; A subset E of R, is statistically upward (resp. downward) compact if any sequence of points in E has a statistically upward (resp.

The stability criterion for downward continuation of surface gravity data with various spatial resolutions over Ireland [PDF]
The differences between local and reference geopotential values are the fundamental quantities of interest in the geodetic boundary value problem approach for connecting independent height reference frames.
