Sky blue index determination method and system based on meteorological elements

Abstract

The invention discloses a sky blue index determination method and system based on meteorological elements, and the method comprises the steps: collecting the meteorological observation data of a meteorological observation station, and carrying out the quality control of the meteorological observation data to obtain a meteorological element database; carrying out webpage search on the blue sky keywords by adopting a semantic engine technology, downloading historical weather phenomenon data of the meteorological observation station by adopting a web crawler technology, and eliminating rain and snow dates from blue sky dates by utilizing the historical weather phenomenon data; transmitting the blue sky date to a meteorological element database for meteorological positioning, extracting meteorological elements corresponding to the blue sky date, and selecting meteorological elements associated with the blue sky and satisfaction conditions of the meteorological elements by using a neural network model to obtain alternative sky blue indexes; and selecting an optimal sky blue index from the alternative sky blue indexes as an urban standard sky blue index by adopting a quality prediction detection method and combining the urban air quality data. According to the method, tThe sky blue index accuracy is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for determining a sky blue index based on meteorological elements. Background technique [0002] With the rapid development of China's economy and the acceleration of urbanization, the problem of air pollution has become more and more serious. The Bureau of Meteorology has defined pollution phenomena such as haze, which facilitates research on the time of heavy haze and helps the government make decisions and solve pollution problems. However, with the development of the Action Plan for Air Pollution Prevention and Control, the blue sky is increasingly appearing in the public's field of vision. Behind the sudden popularity of "Beijing Blue" is people's huge yearning for the blue sky. For the government, in order to test the effectiveness of the “Blue Sky China” plan, to reflect the long-term changes in China’s blue and its relationship to economic ...

AI Technical Summary

Problems solved by technology

However, compared with pollution weather such as smog, blue is a high-probability event, which is ignored by researchers, so there is always a lack of an accurate definition

[0004] Since there is only a definition of haze at present, and the lack of an accurate unified definition of blue, that is, the sky blue index, how to obtain the sky blue index and improve the accuracy of the sky blue index is an urgent problem to be solved
