Abstract

The invention discloses a remote sensing detection system for the condensable water amount of an air cloud system. The remote sensing detection system includes a mie-scattering laser radar which is used for acquiring height values of a cloud bottom and a cloud top, a rotating Raman laser radar which is used for acquiring atmospheric temperature profile data, a wind measurement laser radar which is used for acquiring a vertical movement speed of an air flow, and a micro-rain radar which is used for judging whether rainfall exists. The Mie scattering laser radar, the rotating Raman laser radar, the wind measurement laser radar and the micro rain radar are all connected to the data processing system. The detection method comprises the following steps: 1, vertically observing the sky; 2, obtaining the height of the cloud bottom and the height of the cloud top; 3, calculating the saturated water vapor density of the cloud bottom and the cloud top; 4, obtaining the vertical airflow movement speed;5, calculating the condensable water quantity in the atmosphere within a period of time; and 6, calculating the condensable water quantity in the cloud. according to the invention, high-precision detection of the air condensable water quantity can be realized, and the problem that the air condensable water quantity cannot be observed in the existing atmospheric science field is solved.

Description

technical field [0001] The invention relates to the technical fields of remote sensing technology and atmospheric science, in particular to a detection system for the amount of condensable water in clouds in the sky, and also relates to a detection method for the amount of condensable water in clouds in the sky using the system. Background technique [0002] Atmospheric water resources in my country are very rich, but studies have shown that only 14%-18% of the water vapor in the atmosphere can form precipitation at most, and even only 2% in some arid areas. For example, only 1.78% of the water vapor in Xinjiang falls to the ground, exceeding 98% of the water vapor becomes passing water, which shows that my country's atmospheric water resources have great potential for development. The first step in the development of water resources is to correctly evaluate the amount of cloud water resources in a certain area, that is, the precipitation potential of cloud systems.
