Abstract

The invention relates to the technical field of meteorological element measurement and technology development, and discloses a method and system for indirectly measuring the dew point temperature by amicrowave radiometer, wherein the method comprises the following steps: S1, carrying out data decoding of the microwave radiometer, and extracting the temperature and humidity values of N profiles; S2, automatically identifying an algorithm of each height point of each profile based on temperature and humidity values; S3, calculating the dew point temperature of each height point of the N profiles according to an algorithm matching result; and S4, generating a 0-24-h and 0-10 km dew point temperature hour height map in an imaging manner. According to the method for indirectly measuring the dew point temperature by the microwave radiometer, different algorithms are matched according to different temperature and humidity, dew point temperature values of different height points of each profile are calculated, images are generated, and continuous measurement of the 0-24-h and 0-10 km dew point temperature is achieved; and continuous judgment of atmospheric condition saturation degrees ofdifferent layers of 0-10 km and continuous generation of severe convection forecasting and early warning products serving convection temperature, K index, total index (TT) and the like are provided for a pre-announcer.

Description

technical field [0001] The invention relates to the field of meteorological element measurement and technology development, in particular to a method and system for indirect measurement of dew point temperature by a microwave radiometer. Background technique [0002] The dew point temperature is a physical quantity that reflects the water vapor content in the air, and is also the basic physical quantity for the generation of strong convection forecast and early warning products such as convective temperature, K index, and total index (TT). In terms of business, due to the limitations of instruments, the level of observers, and economic factors, it is difficult to directly measure the dew point temperature with a dew point meter. It is often measured indirectly by using empirical formulas based on meteorological parameters such as temperature and relative humidity measured at stations. The dew point temperature value indirectly measured by the ground observation station only ...
