Variations in solar radiation incident at Earth's surface profoundly affect the human and terrestrial environment. A decline in solar radiation at land surfaces has become apparent in many observational records up to 1990, a phenomenon known as global dimming. Newly available surface observations from 1990 to the present, primarily from the Northern Hemisphere, show that the dimming did not persist into the 1990s. Instead, a widespread brightening has been observed since the late 1980s. This… 
Global dimming and brightening: A review
[1] There is increasing evidence that the amount of solar radiation incident at the Earth's surface is not stable over the years but undergoes significant decadal variations. Here I review the
Global dimming and brightening: An update beyond 2000
TLDR
Overall, the available data suggest continuation of the brightening beyond the year 2000 at numerous locations, yet less pronounced and coherent than during the 1990s, with more regions with no clear changes or declines.
Recent regional surface solar radiation dimming and brightening patterns: inter‐hemispherical asymmetry and a dimming in the Southern Hemisphere
Recent variations in surface solar radiation (SSR) at the beginning of the 21st century (2000–2007) were determined at scales ranging from local/regional to hemispherical/global, on the basis of
SOLAR DIMMING / BRIGHTENING WITHIN THE MEDITERRANEAN
The energy source of life in our planet, which largely determines the climatic conditions, is the solar radiation that incidents on the earth's surface. The amount of solar energy that reaches on
Two‐decadal aerosol trends as a likely explanation of the global dimming/brightening transition
Global average trends in solar radiation reaching the Earth's surface show a transition from dimming to brightening that occurred in about 1990. We show that the inter‐annual trend in solar radiation
Global dimming and global brightening—an analysis of surface radiation and cloud cover data in northern Europe
In the present study, surface solar radiation data from 11 stations in northwestern Europe and the European Arctic are presented in the context of the ongoing discussion on global dimming and global
Changes in atmospheric shortwave absorption as important driver of dimming and brightening
The amount of solar (shortwave) radiation that reaches the Earth’s surface underwent substantial variations over recent decades. Since the 1950s, surface shortwave radiation gradually decreased at
Surface radiation changes and their impact on climate in Central Europe
The rapid temperature increase of 0.7◦C averaged over the Northern Hemisphere and of 1◦C over mainland Europe since 1980 is considerably larger than expected from anthropogenic greenhouse warming.

Do Satellites Detect Trends in Surface Solar Radiation?
TLDR
An estimate of global temporal variations in S is presented by using the longest available satellite record and observing an overall increase in S from 1983 to 2001 at a rate of 0.16 watts per square meter (0.10%) per year.
Changes in Earth's Albedo Measured by Satellite
TLDR
The satellite data show that the last four years are within natural variability and fail to confirm the 6% relative increase in albedo inferred from observations of earthshine from the moon.
Aerosols, Climate, and the Hydrological Cycle
TLDR
Human activities are releasing tiny particles (aerosols) into the atmosphere that enhance scattering and absorption of solar radiation, which can lead to a weaker hydrological cycle, which connects directly to availability and quality of fresh water, a major environmental issue of the 21st century.
The cause of decreased pan evaporation over the past 50 years.
TLDR
It is shown that the decrease in evaporation is consistent with what one would expect from the observed large and widespread decreases in sunlight resulting from increasing cloud coverage and aerosol concentration.
Is the Hydrological Cycle Accelerating?
As global climate warms, most atmospheric scientists believe that evaporation will increase and as a result, the hydrological cycle will accelerate. But results from a network of water-filled pans
