Example Embodiment

[0043] In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

[0044] See figure 1 , Is a flowchart of the method for filling missing temperature data in an embodiment of the present application. The method for filling missing temperature data in the embodiment of the application includes the following steps:

[0045] Step 100: Read the temperature data of the site to be filled, and determine the time when the temperature data of the site to be filled is missing;

[0046] In step 100, the statistical method for the time information of the temperature data missing is specifically: since the meteorological data set includes data sets at different time nodes such as month, day, ho...

Abstract

The invention relates to a temperature missing data filling method and system and electronic equipment. The method comprises the following steps: step a, respectively reading temperature data of a to-be-filled station and each observation station located in the same region as the to-be-filled station, and counting a common time sequence of the to-be-filled station and each observation station according to the temperature data; b, calculating a correlation coefficient between the to-be-filled station and each observation station by utilizing the temperature data of the common time sequence of the to-be-filled station and each observation station at the corresponding moment, and screening out at least one observation station with the strongest correlation with the to-be-filled station as a filling reference station according to the correlation coefficient; and step c, fitting a linear function between the to-be-filled station and the at least one filling reference station by utilizing the temperature data of the at least one filling reference station at the moment corresponding to the common time sequence, and filling the temperature data of the to-be-filled station through the linear function. According to the invention, the accuracy and operability of temperature data filling are improved.

Description

technical field [0001] The application belongs to the technical field of meteorological services, and in particular relates to a method, system and electronic equipment for filling missing temperature data. Background technique [0002] The temperature data is measured by the meteorological observation station through some equipment or manual methods, and then entered into the data through the computer system. On the one hand, the density of meteorological observation stations in various regions of my country is relatively high at this stage, and the equipment is prone to failure over time, which undoubtedly increases the possibility of data loss at each observation station. On the other hand, data omissions may also occur during the entry process of the computer system. The lack of temperature data will to a certain extent lead to deviations in the statistical analysis results of meteorological researchers, which will affect the formulation of corresponding measures by rel...
