Novel actual measurement method for vertical profiles of multiple atmospheric parameters on basis of aerostat carrying

Abstract

The invention discloses a novel method for obtaining vertical profiles of multiple atmospheric parameters simultaneously. According to the method, measurement devices based on various principles and capable of measuring multiple parameters simultaneously are fixed on a cable of an aerostat at specified intervals, finish measurement of the atmospheric parameters at the height and transmit data to ground acquisition equipment in real time, and real-time measured vertical profiles of the multiple atmospheric parameters are obtained synchronously. The profile data has no prerequisite of assumption, and calibration data can be provided for ground remote sensing equipment such as radar and the like performing measurement at the same site while conventional meteorological parameters and atmospheric pollution data are provided for meteorological department and environmental governance department. Developed equipment is good in timeliness, high in automation degree and measurement precision, stable in work and reliable in performance.

Description

technical field [0001] The invention relates to a new method for obtaining vertical profiles of multiple atmospheric parameters (including meteorological parameters, pollutants and optical parameters). Through the arrangement of measuring equipment in the vertical direction, the synchronous measurement of atmospheric parameters at the location of the equipment is realized. While measuring the vertical profile of parameters in real time, it provides calibration data for the inversion results of remote sensing equipment such as radar and satellite. Background technique [0002] The detection of atmospheric parameters is the necessary input parameters and reference basis for meteorological and environmental protection departments to grasp the atmospheric conditions, forecast meteorological and air quality, and formulate corresponding emergency control strategies. With the increasing emphasis on environmental governance in my country, the release of sounding balloons Traditional ...

Problems solved by technology

[0006] Satellites are one of the fastest and most effective means of obtaining large-area or global atmospheric information. For example, MODIS has 36 channels, of which channels 31 and 32 can be used for inversion of surface temperature. However, various satellite inversions are based on assumptions Yes, in the actual measurement, there will always be situations that deviate from the assumptions, and the resolution of the satellite is usually around 1000m or even greater. The data is too rough, and the guiding significance for local atmospheric information is rapidly weakened.
