China haze, temperature inversion, poor air quality

Beijing Shrouded in Brown Haze
Coal-fired Power Plants and Essential Clean Air are Diametrically Opposite to Each Other
Haze blanketed Beijing, China, on January 18, 2010, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image. The entirely image is brown, as if covered by a thin film. The image also hints at a contributing factor to the poor air quality: a temperature inversion, contributing to the buildup of pollutants.

(MODIS) on NASA’s Aqua satellite, January 18, 2010. The gray-brown haze extends from Beijing to the South China Sea from north to south and from Korea to central China from east to west (shown in the large image). This image shows the densely populated and industrialized North China Plain between Beijing and the Yangtze River, where the haze is so dense that it completely obscures the ground.

how can I know the grey-brown area is the haze? what is the gist to consider that the grey-brown area is the haze? I’m looking forward the answer.

The image was acquired by NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) which can determine chemical or spectral signature for airborne particles.
