Abstract

The invention discloses a meteorological station multi-source data integration method, which comprises the following steps: performing gridding division on a research area, removing an area which is not covered by a station, establishing a station mathematical programming model, and constructing a typical station and an alternative multi-source station; determining a secondary sampling period according to the sampling interval of the observation station and the final application requirement of the meteorological data, and carrying out secondary integration processing on the multi-source data by adopting a proximity value, interpolation and weighting mode in combination with the station type and the data time scale; and calculating to each grid point on the basis of the typical site integrated data. The method provided by the invention solves the problems of typical site selection with similar sites in a region, data integration of meteorological elements, acquisition frequency, inconsistent data time scales and the like, data loss, delayed uploading and the like, and can be applied to a data acquisition and processing unit system constructed by a meteorological system.

Description

technical field [0001] The invention relates to a multi-source data integration method of a meteorological station, belonging to the technical field of grid meteorological information application. Background technique [0002] With the wide application of meteorological information, more and more institutions have established their own meteorological observation stations, real-time monitoring and comprehensive application of meteorological information; Micro weather stations (substations, towers) built by the company, rainfall stations built by the water conservancy department, meteorological observation stations built by the transportation department, etc. [0003] During the construction of the power grid meteorological information application system, the monitoring information of various meteorological stations within the region is usually integrated and comprehensively applied. In the comprehensive application of meteorological monitoring data, the following problems us...
