Haze over China (MODIS), On November 7, 2022, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired a true-color image of a thick haze hovering over eastern China., A thick aerosol haze blanketed North Central China on the opening days of 2023. The Moderate Resolution Imaging Spectroradiometer acquired a true-color image of a gray blanket swathing the region on January 3.

The haze is so thick that it obscures most of the North China Plan, the agricultural heartland of the country, from view. Beijing, the country’s capital city, is hidden under the aerosol haze in the upper left (northeast) section of the image. The gray shroud thins against the Western Hills (Xishan) as the elevation rises, but seeps into valleys and over rivers where it forms sinuous and branching patterns.

Outbreaks of severe haze in this region are frequent, especially during cooler temperatures. They generally occur during the winter because of temperature inversions. Air normally cools with altitude, but during an inversion warm air settles above a layer of cool air near the surface. The warm air acts like a lid and traps pollutants near the surface, especially in basins and valleys. Common sources of pollution in the winter include coal and wood burning for heat, industrial activity, and vehicle emissions. Smoke from fires and dust storms can also contribute to poor air quality.
