Starting today, the concentration of fine dust produced by the Chollian Environmental Satellite will be revealed.

The National Institute of Environmental Research announced that starting today, it will provide real-time numerical data on estimates of fine dust and ultrafine dust concentration calculated by analyzing observations from Chollian Satellite 2B, a geostationary environmental satellite.

Using the numerical data released this time, the concentration of fine dust on the Korean Peninsula and surrounding areas can be checked over time and compared with the concentration measured on the ground or calculated by air quality models.

The estimated concentration of fine dust on the ground is a value converted to concentration on the ground by applying artificial intelligence techniques to the entire layer of the atmosphere observed by environmental satellites.

Since the first video release of the estimated concentration of fine dust on the ground in December 2021, the Environmental Satellite Center has compensated for the difference between the estimated concentration of fine dust and the actual observed concentration on the ground through verification every year.

This data can be received on the website of the Environmental Satellite Center, and it also plans to provide user instructions to enhance user understanding of environmental satellite data.
