Variations in the cloud-base height over the central Himalayas during Ganges Valley Aerosol experiment: association with the monsoon rainfall
<p>We present the measurements of cloud-base height variations over ARIES, Nainital (79.45°E, 29.37°N, 1958 m amsl) obtained from Vaisala Ceilometer, during the nearly year-long Ganges Valley Aerosol

New early-warning system could protect Earth from explosive space weather
The sun can erupt with flares more energetic than 30 billion times the yield of all nuclear weapons ever detonated. The energetic particles released by solar flares tunnel a path through our inner solar

Direct radiative effect by brown carbon over the Indo-Gangetic Plain
<p>The importance of light-absorbing organic aerosols, often called brown carbon (BrC), has become evident in recent years. However, there have been relatively few measurement-based estimates for the direct

An increase in aerosol burden and radiative effects in a warmer world
Atmospheric aerosols are of significant environmental importance, due to their effects on air quality, as well as their ability to alter the planet’s radiative balance. Recent studies characterizing the

Global dimming and urbanization: did stronger negative SSR trends collocate with regions of population growth?
<p>Global dimming refers to the decrease in surface solar radiation (SSR) observed from the 1960s to the 1980s at different measurement sites all around the world. It is under debate whether anthropogenic

Temperature rise more in winter months than in summer
The warmth of winter months has increased significantly over the past 100 years. Data of the India Meteorological Department (IMD) for the past 114 years revealed that the increase in temperature had

Impacts of wind stilling on solar radiation variability in China
<p>Solar dimming and wind stilling (slowdown) are two outstanding climate changes occurred in China over the last four decades. The wind stilling may have suppressed the dispersion of aerosols and amplified

All-sky direct radiative effects of urban aerosols in Beijing and Shanghai, China
Aerosol particles can directly alter the radiation balance by scattering and absorbing incident solar radiation, thus decreasing the amount of light reaching the surface and increasing the fraction of

ARIES, Nainital: a strategically important location for climate change studies in the Central Gangetic Himalayan region
<p>ARIES, acronym for Aryabhatta Research Institute of Observational Sciences, located in the Central Gangetic Himalayan (CGH) region is emerging as one of the unique sites for climate change studies.

Modelled and observed changes in aerosols and surface solar radiation over Europe between 1960 and 2009
<p>Substantial changes in anthropogenic aerosols and precursor gas emissions have occurred over recent decades due to the implementation of air pollution control legislation and economic growth. The response
