WebFinally, Gaussian smoothing (Jekeli 1981) is applied. We test various radii for the Gaussian function, from 500 km to 0 km in order to evaluate which represents the best agreement wih steric corrected altimetry in the Black Sea. Since the degree-one coefficients are not part of these GRACE solutions, an estimate of WebBack to Results.

Weband Jekeli (1981). The contents of this paper have been organised as follows. The derivations of the strict integral formulas for the geoid and gravity anomaly biases are outlined in Sect. 2. The next section introduces the corresponding binomial expansions. It is then shown how the geoid bias can be used in geoid determination by an EGM and Web25 giu 2024 · Limited by the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) measurement principle and sensors, the spatial resolution of mass flux solutions is about 2–3° in mid-latitudes at monthly intervals. To retrieve a mass flux solution in the Tibetan Plateau (TP) with better visual spatial resolution, we … scott hollington md ormond

After this step, 300 km Gaussian smoothing [Jekeli, 1981] is applied, and the mean of the 43 solutions is removed to obtain time series of gravity field variations. Additional filtering was applied as described below.
