Delhi Pollution: NASA Image Depicts ‘River of Smoke’ Covering City, Partly Caused by Stubble Burning

Air pollution in the Delhi-NCR region has been an alarming problem over the years. The pollution level rises significantly during winters, covering the city with thick fog. A new NASA discovery has identified a cause of this problem. Images tweeted by The Weather Channel India show that stubble burning activities in neighboring states partly cause pollution in the region. Satellite images captured by NASA show stubble plumes moving from these states towards Delhi-NCR. The caption of the photo read, “Every winter, pollution in Delhi rises very rapidly, partly due to stubble burning activities in neighboring states. Now, NASA has captured satellite images showing Delhi moving towards The feathers of the stubble are visible.”

Weather Channel India has told about the process of stubble burning. Farmers usually burn their crop residues to prepare the fields for the next season. “This annual activity is further exacerbated by repeated seasonal pollution,” the tweet read.

Often, there is also an increase in air pollution due to low air currents during this season. However, this year’s sluggish monsoon helped control the rise in pollution levels in early November. But after that the pollution increased. As of November 16, NASA has identified more than 74,000 fire hotspots in Punjab.

USRA scientist Pawan Gupta of NASA’s Marshall Space Flight Center talks about pollution levels on Nov. “A conservative estimate is that at least 22 million people were affected by the smoke in this one day,” he said.

During winter the process of stubble burning accelerates and hence pollution increases.

The tweet thread states that due to the drop in temperature and lack of winds in the winter months, air pollutants are trapped in the atmosphere for a longer time. Ultimately, this leads to various health hazards.

Delhi’s pollution has become a matter of concern this year as well.
