Information system for dynamic space-time environment quality monitoring based on multi-source radar

Abstract

The invention discloses an information system for dynamic space-time environment quality monitoring based on a multi-source radar, and relates to the technical field of atmospheric environment protection. According to the invention, the pollutant automatic monitoring and identification module obtains pollutant components and meteorological factors in the atmosphere collected by each site for real-time 3D observation; s-shaped cutting is carried out on the original observation data, binarization processing and morphological change processing are carried out, and a specific pollutant appearing area is framed on a map; and the pollutant space transmission trend measurement module performs standardization processing on each observation index, and the projected wind speed and standard pollutant concentration data are integrated in time and space dimensions to obtain pollutant transmission flux in a specified direction. According to the invention, through all-weather and real-time 3D area accurate observation of the air, analysis is carried out according to the data observed by the multi-source radar to automatically identify the spatial and temporal distribution of the atmosphere component abnormal time period, so that automatic 3D real-time joint monitoring of the monitoring area is realized.

Description

technical field [0001] The invention belongs to the technical field of atmospheric environment protection, and in particular relates to an information system for monitoring dynamic space-time environmental quality based on multi-source radar.
