Abstract

The application relates to a method and system for monitoring a urban heat island effect based on a domestic satellite. The monitoring method includes: preprocessing remote sensing data provided by the domestic satellite; performing atmospheric correction on the preprocessed remote sensing data by using a predetermined model, and estimating the earth's surface emissivity; inverting the earth's surface temperature based on the data preprocessing, the atmospheric correction, and the estimated earth's surface emissivity; and drawing a correlation graph corresponding to the earth's surface temperature and/or heat island intensity according to the inverted earth's surface temperature and monitoring the urban heat island effect based on the correlation graph. The method and system can make use of the data of the domestic satellite, quantitatively invert the earth's surface temperature, construct and form a variety of thematic maps and profile maps to realize the quantitative monitoring of the urban heat island effect.

Description

technical field [0001] This application relates to the technical field of heat island effect monitoring, in particular to a domestic satellite-based urban heat island effect monitoring method and system. Background technique [0002] Land surface temperature is a key parameter of radiation and energy exchange between the land surface and the atmosphere, as well as regional and global surface physical processes. Thermal infrared remote sensing is an effective means to detect land surface temperature. Environment-1 Satellite A, B (HJ-A / B) is a brand new civil satellite launched in 2008 by our country after meteorological, oceanographic and land resources satellites. The thermal infrared band spatial resolution of the infrared camera (IRS) on the HJ-1B satellite is 300m. There are not many thermal infrared studies on this star, and they mainly focus on the early stage of model simulation, on-orbit evaluation, or relatively complex inversion process. For example, Duan Sibo et a...
