A rainfall observation method integrating satellite remote sensing and mobile communication base station signals

Abstract

The invention discloses a rainfall observation method integrating satellite remote sensing and mobile communication base station signals, which comprises the following steps of: for each microwave link in a target area, respectively establishing the connection between rain attenuation and rain intensity by adopting different rain attenuation and rain intensity models, and deducing the corresponding link rainfall intensity; dividing grids for the target area, and deducing the regional rainfall capacity under different rain attenuation and rain intensity models in the historical period; optimizing a rain attenuation and rain intensity model through large-scale observation data in a historical period of satellite remote sensing; and observing real-time rain intensity information with high spatial resolution based on real-time dynamic rain attenuation data of the mobile communication base station by adopting the optimized rain attenuation and rain intensity model. The method gives full play to the advantages of a satellite remote sensing rainfall observation technology and a microwave link real-time rainfall intensity observation technology, provides a real-time, dynamic and high-precision rainfall observation mode, and can provide important and highly operable reference basis for flood prevention and disaster reduction and drainage basin planning.

Description

technical field [0001] The invention relates to the technical field of rainfall observation, in particular to a rainfall observation method which integrates satellite remote sensing and mobile communication base station signals. Background technique [0002] Rainfall is an important meteorological monitoring data in many industries or fields such as agriculture, forestry, water conservancy, hydrology, and mining. It is of great significance to industrial and agricultural production, water conservancy development, river flood control, and project management. At present, the reasonable accuracy of rainfall observation data is an important requirement in many fields such as urban planning, water resource development, flood control and early warning, and is related to the health and stability of the ecological environment and sustainable economic and social development. [0003] China's current rainfall data mainly rely on satellite remote sensing, radar and ground rainfall stat...

Problems solved by technology

[0007] However, the existing literature usually can only obtain the rainfall value along the link on the communication path, and the hydrometeorological field requires regional rainfall data, and the existing methods are difficult to meet the requirements; at the same time, due to the lack of measurement verification data, the existing methods can only be subjective Selecting a model to establish the relationship between rain intensity and rain attenuation has great uncertainty and arbitrariness, and cannot solve the problem of regional rainfall observation
