Abstract

The invention provides an aerosol foundation data-based AOD (Aerosol Optical Depth) vertical correction effect evaluation method and system. The method comprises the steps of estimating a near-surface aerosol extinction coefficient and inverting the near-surface aerosol extinction coefficient based on observation data of a foundation visibility meter; inverting AOD based on observation data of a foundation sum photometer; inverting the near-surface aerosol extinction coefficient based on the visibility meter; performing vertical correction on the AOD based on a laser radar observation method or an atmospheric chemistry mode simulation method, and estimating the near-surface aerosol extinction coefficient according to a vertical correction result; and evaluating the effect and applicability of an AOD vertical correction method by comparing the difference between the estimated near-surface aerosol extinction coefficient with the inverted near-surface aerosol extinction coefficient. According to the method and the system, the errors caused by direct use of a satellite for AOD inversion and the evaluation uncertainty caused by a scale effect and the like can be avoided, so that the difficult problems in effect evaluation and applicability selection among various AOD vertical correction methods and various data sources are solved.

Description

technical field [0001] The invention relates to the field of air quality satellite monitoring, and more specifically, to an evaluation method and system for AOD vertical correction effect based on aerosol ground-based data. Background technique [0002] With the rapid development of the economy, the sharp increase of man-made emissions such as industrial activities and motor vehicle exhaust, the air quality in the central and eastern regions of my country has continued to deteriorate. my country's Yangtze River Delta, Pearl River Delta, Beijing-Tianjin-Hebei and other typical urban agglomerations have serious PM2.5 (PM2.5 refers to particulate matter with an aerodynamic particle size of less than 2.5 μm in the air) pollution, resulting in frequent haze weather. A large number of environmental epidemiological studies have found that epidemiological studies have proved that PM2.5 is associated with asthma, respiratory infections, lung cancer, and cardiovascular diseases. PM2....
