Description

Server, method and computer program for providing weather data to a terminal with expanded spatiotemporal resolution The present invention relates to a server, a method, and a computer program that receive weather data from a weather model, enlarge the spatiotemporal resolution, and provide it to a terminal. Weather forecasting is performed using global weather models such as GFS and ECMWF, which enable the acquisition of weather data over large-scale spatial areas. These models are primarily used to monitor atmospheric conditions and forecast future weather, and the collected data is applied to various industrial sectors, including agriculture, energy management, aviation, and maritime transport. In particular, the spatiotemporal resolution of meteorological data is a critical factor that significantly impacts the accuracy of real-time climate monitoring and prediction, and its importance is increasing as the impact of weather changes intensifies. Meanwhile, the spatiotemporal resolution provided by current global weather models is structured around broad regional units. This is because resolution is often limited to reduce computational burden due to the inherent characteristics of the models, which limits the ability to obtain detailed weather information for specific or small-scale regions. Consequently, various industries seeking to utilize weather data are demanding an expansion of resolution, as the spatiotemporal resolution provided by existing models is insufficient. FIG. 1 is a configuration diagram of a system that expands the spatiotemporal resolution of weather data and provides it to a terminal, according to one embodiment of the present invention. FIG. 2 is a block diagram of the server shown in FIG. 1 according to one embodiment of the present invention. FIG. 3 is an exemplary drawing for explaining a method of providing weather data to a terminal by enlarging the spatiotemporal resolution of the weather data by a server according to an embodiment of the present invention.

FIG. 5 is a flowchart illustrating a method for providing weather data to a terminal by expanding its spatiotemporal resolution according to an embodiment of the present invention. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement the invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification are denoted by similar reference numerals. Throughout the specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "electrically connected" with other components interposed between them. Furthermore, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. In this specification, the term "part" includes a unit realized by hardware, a unit realized by software, and a unit realized using both. Additionally, one unit may be realized using two or more hardware, and two or more units may be realized by one hardware.
