In this paper, we have studied the role of aerosols in the interplay between land and sea during two weak and three strong episodic events, namely, La Nina [2005 (weak), 2008 (strong) and 2010 (strong)] and El Nino [2006 (weak) and 2009 (strong)]. Fo

Climatologically, high Aerosol Optical Depth (AOD500 nm) >0.1 during spring and very low AODs (∼0.05) during the summer months persist over the Arctic. Unusually high values of AOD are unknown to be observed during Arctic summers; however using MIC

Biomass burning activity captured the attention of the scientific community because of its significant impact on global climate change. In this paper, we present the results of a study of variations in aerosol optical, microphysical and radiative pro

In this study, we deal with observations of aerosol column content (height integration of vertical distribution of aerosol number density) that have been carried out using an Ar+ lidar for three different measurement cycles (each cycle consisting of

The present study deals with a major summertime dust storm event that occurred over the Arabian Desert, Saudi Arabia SA, and the United Arab Emirates UAE and spread to Pakistan, the Arabian Sea, and Western India in particular over Alibaug and Pune,

Black carbon (BC) aerosols are emitted into the atmosphere as a byproduct of different combustion processes and are reported to be a very strong absorber of solar radiation. In this paper, we present results on BC aerosols over Pune, a tropical urban

Observational evidence of two-way association between nocturnal boundary layer aerosols and cloud macrophysical properties over a tropical urban site is reported in this paper. The study has been conducted during 2008–09 employing a high space–ti

A coherent Doppler wind lidar was installed in July2009 at the Indian Institute of Tropical Meteorology (IITM), Pune (18°43'N, 73°51'E, 559m AMSL), India, to map the daily three-dimensional wind fields in the atmospheric boundary layer (ABL). T

Aerosols affect clouds in two broad ways: (i) presence of more number of aerosols leads to formation of more smaller droplets, and reduces coalescence, resulting in brighter clouds that reflect more solar energy back to space, hence they contribute t
