Abstract: A method for visualizing weather data via a GUI accessible via a computer display is provided. The GUI provides a map view for displaying a weather map image and an interactive time selection view for displaying a time selection image. The method comprises composing the time selection image that depicts an arrangement of symbols jointly representing a current time period, each symbol representing a respective sub-period of time within the current time period and having an appearance that is descriptive of at least one precipitation characteristic in one or more precipitation data records that include weather data for the respective sub-period of time; receiving an indication of a user-selected time instant; and composing the weather map image by overlaying a weather image on a map image, wherein the weather image is derived on basis of a precipitation data record that includes weather data for the user-selected time instant.

Abstract: The present invention concerns a method and system for gas concentration measurement of gas or gas mixtures dissolved in liquids. A gas or gas mixture dissolved in a liquid sample is extracted from the liquid sample using an extraction system and conducted into a measurement chamber. Then a measurement signal is generated by means of a radiant source and the measurement signal is directed to a measurement object in a measurement chamber containing the gas or gas mixture to be measured. The measurement signal is filtered using at least two wavelengths, whereupon the filtering is preferably implemented by means of an electrically tunable, short-resonator Fabry-Perot interferometer. Then the filtered measurement signals are detected my means of a detector.
