Gravityfield2GridCovarianceMatrix
This program propagates the covariance matrix of a gravityfield evaluated at time to a grid. The full variance-covariance matrix is computed and written to a matrix file: \[ \mathbf{\Sigma}_\mathbf{y} = \mathbf{F}\mathbf{\Sigma}_\mathbf{x}\mathbf{F}^T \]The kernel determines the quantity of the grid values, for example, kernel:waterHeight.
