Embodiment

[0056] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention provides a system for monitoring heat island intensity, comprising:

[0057] A GNSS receiver city site, which is set in the city and is used to obtain observation data of the GNSS receiver city site;

[0058] A GNSS receiver suburban site, set in the suburbs adjacent to the city, for obtaining GNSS receiver suburban site observation data;

[0059] A sounding station, which is set up near the ground in cities and suburbs, is used to detect the atmospheric refractivity at various heights from the ground;

[0060] The data information obtained by GNSS receiver urban stations and sounding stations is used to calculate the temperature of GNSS receiver urban stations, and the data information obtained by GNSS receiver suburban stations and radiosonde stations is used to calculate the temperature of GNSS receiver suburban stations. The difference between the temperature of the site and t...

Embodiment approach

[0066] As a preferred embodiment of the present invention, step S1 includes:

[0067] Step S11: Use the ERA5 [The Fifth Generation ECMWFAtmospheric Re-analysis, ECMWF (European Center for Medium-Range Weather Forecasts, European Center for Medium-Range Weather Forecasts, European Center for Medium-Range Weather Forecasts) to extract the fifth generation atmospheric re-analysis of the global climate] data set The historical one-hour resolution air pressure value and water pressure value around the GNSS receiver city site are fitted to the extracted air pressure value and water pressure value, and an atmospheric empirical model of urban air pressure and water pressure parameters is established;

[0068] Step S12: According to the atmospheric empirical model established in step S11, calculate the air pressure or water pressure empirical value at any time around the GNSS receiver city site;

[0069] Step S13: Obtain the atmospheric refractivity at each height through the historica...

Abstract

The invention discloses a system and method for monitoring the intensity of a heat island, and the system comprises a GNSS receiver city site which is disposed in a city and is used for obtaining the observation data of the GNSS receiver city site, a GNSS receiver suburb site arranged in a suburb adjacent to the city and used for acquiring observation data of the GNSS receiver suburb site, and a sounding station arranged at the near-ground overhead position of the city and the suburban area and used for detecting the atmospheric refractive index at each height from the ground. The method comprises the following steps: S1, calculating the temperature of a GNSS receiver city site; S2, calculating the temperature of the suburb site of the GNSS receiver; and S3, subtracting the temperature of the urban site and the temperature of the suburban site to obtain the heat island intensity. The invention provides a novel method for inverting the intensity of the heat island by using a cheap GNSS receiver in combination with an atmospheric empirical model, and the application of the current GNSS in the aspect of heat island effect monitoring is expanded.

Description

technical field [0001] The invention relates to the field of geodetic surveying technology and meteorological disaster monitoring, in particular to a system and method for monitoring heat island intensity. Background technique [0002] UHIE (Urban Heat Island Effect, Urban Heat Island Effect) is a typical feature of urban climates. When the temperature in an urban area is higher than that in its surrounding rural areas, a heat island effect will appear. [0003] The causes of the urban heat island effect include: cities are densely populated, vehicles and industrial plants release a lot of heat; urban ground or buildings absorb heat, resulting in a rapid rise in temperature; urban dense buildings and tall buildings make it difficult to dissipate heat. Long-term, high-intensity urban heat islands are likely to cause weather events such as air pollution and heat waves, which in turn pose a threat to human life. Therefore, monitoring and effective management of UHII (Urban Hea...
