Abstract: In a method for determining, in particular predicting, at least one meteorological quantity for describing a current and/or past and/or future weather situation using a data processing device, (a) first meteorological parameters obtained from first measurements are assigned to grid points of a first grid. In the method, (b) at least one setting parameter, which can be entered via an interface, in particular a user interface, is received, and (c) the at least one meteorological quantity is determined from the first meteorological parameters, dependent on the at least one setting parameter, by applying a first algorithm, wherein preferably, the determined meteorological quantity is output at a user interface and/or is transmitted by an electronic message sending device.

Abstract: In a method for increasing the spatial resolution of a weather forecast, in which forecast predicted meteorological parameters are available for grid points of a first grid and the predicted meteorological parameters are interpolated to grid points of a second grid so as to obtain interpolated meteorological parameters, wherein the grid points of the second grid have a higher spatial resolution than the grid points of the first grid, a statistical postprocessing method is used to predict at least one output quantity of an analysis method by which forecast meteorological parameters can be interpolated to the grid points of the second grid.

Abstract: The invention relates to a method of determining at least one meteorological quantity (iwvc, ilwc, rr) for describing a state of atmospheric water, in particular of water vapor (wv), condensed water (lw) and/or precipitation (r), comprising the following steps: (a) providing meteorological input data (d1), (b) step in which—for at least one state (wv, lw) of the atmospheric water—second data (d2) are calculated from the meteorological input data (d1), said second data (d2) representing a measure of the signal attenuation of signals transmitted though the atmosphere (A), said signal attenuation being caused by said at least one state (wv, lw), (c) providing third data (d3), which represent a measure of the signal attenuation of signals caused by atmospheric water, wherein the third data (d3) are obtained from the measurement of signals (3) which have been transmitted through the atmosphere (A) between signal transmission devices (1,2), in particular between signal transmission devices on satellites (1) and te
