The instrument, the Total and Spectral Solar Irradiance Sensor (TSIS-1), is said to be capable of precisely measuring what researchers call “total solar irradiance”. According to NASA ...

Caption A graph of the sun's total solar irradiance shows that in recent years irradiance dipped to the lowest levels recorded during the satellite era. The resulting reduction in the amount of ...

The conditions have been particularly dry in the Amazon basin, favoring wildfire activity, and the resulting smoke has reduced solar irradiance along the plume’s path. This winter brought dry ...

Researchers used both historical and modeled data from multiple wildfire seasons to analyze the impact on solar power. They ...
