Aerosol vertical profiles strongly affect their radiative forcing uncertainties: study by using ground-based lidar and other measurements

Reddy, K.; Phanikumar, D. V.; Ahammed, Y. N.; Naja, M. (Taylor & Francis, 2013-08-28)

In the present study, we illustrate for the first time that direct aerosol radia- tive forcing has large uncertainty due to diversity in simulated vertical profile of aerosol over Manora Peak, Nainital (considered to be ...
Effect of cloud reflection on direct aerosol radiative forcing: a modelling study based on lidar observations

Reddy, K.; Ahmmed, Y. N.; Phanikumar, D. V. (Taylor & Francis, 2014-03-18)

In the present study, we have utilized light detection and ranging (lidar) and sun photometer observations to derive vertical distribution and optical depth of aerosols over Manora Peak (29.54° N, 79.45° E, 1956 m above ...
Effects of dust aerosols on tropospheric chemistry during a typical pre-monsoon season dust storm in northern India

Kumar, R., et al.; Naja, M.; Ojha, N.; Sarangi, T. (The European Geosciences Union., 2014-07-04)

This study examines the effect of a typical pre-monsoon season dust storm on tropospheric chemistry through a case study in northern India. Dust can alter pho- tolysis rates by scattering and absorbing solar radiation ...
Latitudinal variation of aerosol properties from Indo- Gangetic Plain to central Himalayan foothills during TIGERZ campaign

Dumka, U. C.; Tripathi, S. N.; Misra, Amit; Giles, D. M.; Eck, T. F.; Sagar, R.; Holben, B. N. (AGU Publication, 2014-03-30)

As part of TIGERZ campaign, latitudinal variation of aerosol optical properties was analyzed over Indo-Gangetic Plains (IGP) to central Himalayas during premonsoon of 2008 and 2009. Measurements of aerosol optical depth ...
Spatial variation of aerosol optical depth over Arabian Sea: effect of long-rang transport

Saha, A.; Moorthy, K. K. (2004)

The spatial variation of aerosols is strongly coupled to the location of the source regions and prevailing atmospheric circulation, which transport the aerosols far away from the source regions. Thus, the concentration and ...
Spectral characteristics and columnar size distribution of aerosols over Arabian Sea and tropical Indian ocean

Saha, A.; Moorthy, K. K. (2004)

Size distribution is one of the most prominent properties of atmospheric aerosols. Most of the effects of aerosols can be understood only with the knowledge of its size distribution. The direct and indirect radiative effects ...
Study of Aerosols Characteristics over Central Himalayas

Joshi, Hema (ARIES, Nainital, 2015-07)
A study on dynamical aspects of aerosols over the Central Himalayan region

Shukla, Krishna Kumar (ARIES, Nainital, 2015-12)

The variability in the physical/optical and chemical properties of aerosols showedthe different kinds of dynamical aspects on the regional and globalscales. Thestudies of dynamical aspects of aerosols over a high altitude ...
Surface changes in solar irradiance due to aerosols over central Himalayas

Dumka, U. C.; Satheesh, S. K.; Pant, P.; Hegde, P.; Moorthy, K. K. (2006)

During a comprehensive aerosol field campaign as a part of the ISRO-GBP, extensive measurements of radiative fluxes at the surface were made during December 2004 at Manora Peak, in the Shivalik ranges of the Central ...
Wintertime spatial characteristics of boundary layer aerosols over peninsular India

Moorthy, K. K., ...et al. (including Saha, A.) (2005-04-30)

During an intense field campaign for generating a spatial composite of aerosol characteristics over peninsular India, collocated measurements of the mass concentration and size distribution of near-surface aerosols were ...
