Scientists recorded changes in the amount of solar radiation on the surface of the world 14:00

The amount of sunlight reaching the surface of the world may vary significantly over time. This result was reached by an international group of researchers led by Professor Martin Wilde of the Swiss Federal Institute of Technology. Published in İş Magazine Developments in atmospheric Sciences (AAS).

Researchers have analyzed long-term observation data and concluded that a global “darkening” was observed from the 1950s to the 1980s. Since the 1990s, the reverse tendency has begun-a partial restoration of the sunflow associated with the improvement of the environmental situation.

The authors of the article paid special attention to China, which provides unique conditions to examine the effect of the atmosphere on solar radiation.

“China has a wide meteorological observation network and long -term data archives, which makes it one of the most studied countries in the context of darkening and enlightenment,” said Professor Vild.

A decrease in solar energy in China caused air pollution, especially from the 1960s to 1990s. However, since the beginning of the 2000s, the situation has started to change: it has given as a result of pollution -fighting measures and solar energy began to reach the surface in large volumes.

“If China manages to fully restore the purity level of the atmosphere observed in the 1960s, it can significantly increase the effectiveness of solar energy,” Vild said.

He also added that such changes are important not only for climate and ecology, but also to evaluate the resources in the field of solar energy that develops actively.

According to the authors, changes in solar radiation affect many areas from climate and agriculture to human health and energy, so monitoring of these processes should become a priority for scientific research.
