Optical and physical properties of aerosols during active fire events occurring in the Indo-Gangetic Plains: Implications for aerosol radiative forcing

Shantikumar, N. S; Dumka, U. C; Srivastava, A. K; Song, H. -J (Elsevier B. V, 2020-02-15)

The climatological characteristics of biomass burning over the western Indo-Gangetic Plain (IGP) are examined during the post-monsoon (October-November) season from 2001-2018 using the Moderate resolution Imaging Spectrometer ...
An overview of and issues with sky radiometer technology and SKYNET

Nakajima, T; Campanelli, M; Che, Huizheng; Estelles, V; Irie, Hitoshi; Kim, Sang-Woo; Kim, Jhoon; Liu, Dong; Nishizawa, T; Pandithurai, Govindan; Soni, Vijay Kumar; Thana, Boossarasiri; Tugjsurn, Nas-Urt; Aoki, Kazuma; Sujung Go; Hashimoto, Makiko; Higurashi, Akiko; Kazadzis, Stelios; Khatri, Pradeep; Kouremeti, Natalia; Kudo, Rei; Marenco, Franco; Momoi, Masahiro; Shantikumar, N. S; Ryder, Claire L; Uchiyama, Akihiro; Yamazaki, Akihiro (European Geosciences Union, 2020-08)

This paper is an overview of the progress in sky radiometer technology and the development of the network called SKYNET. It is found that the technology has produced useful on-site calibration methods, retrieval algorithms, ...
Silver linings in the dark clouds of COVID-19: Improvement of air quality over India and Delhi metropolitan area from measurements and WRF-CHIMERE model simulations

Dumka, U. C; Kaskaoutis, D. G; Verma, Shubha; Shantikumar, N. S; Sarvan Kumar; Ghosh, Sanhita (Elsevier B.V., 2021-02)

The current study examines the impact of the COVID-19 lockdown (25th March until May 17, 2020) period in particulate matter (PM) concentrations and air pollutants (NOx, SO2, CO, NH3, and O3) at 63 stations located at Delhi, ...
Temporal asymmetry in aerosol optical characteristics: A case study at a high-altitude station, Hanle, in Ladakh region

Shantikumar, N. S; Bagare, S. P; Srivastava, A. K; Kanawade, V. P; Rajendra, B. S; Padhy, S. K (Elsevier, 2014-12)

Diurnal features of aerosol optical depth (AOD) at a high-altitude station, Hanle (4500 m amsl) in the western Himalayas, were studied using direct/diffuse solar irradiance measurement from a Skyradiometer (Prede) during ...
Validation of water vapor retrieval from Moderate Resolution Imaging Spectro-radiometer (MODIS) in near infrared channels using GPS data over IAO-Hanle, in the trans-Himalayan region

Shantikumar, N. S; Jade, S; Shrungeshwara, T. S; Song, H.-J (Elsevier B.V, 2016-01)

Integrated precipitable water vapor (PWV) retrieved from Moderate Resolution Imaging Spectro-radiometer (MODIS) in near-infrared channels is examined with the PWV estimated from the Global Positioning System (GPS) data and ...
Variability of sunspot cycle QBO and total ozone over high altitude Western Himalayan regions

Shantikumar, N. S (Elsevier B.V., 2011-10)

Long-term trend of total column ozone at high altitude region in Ladakh is studied, using a total ozone mapping spectrometer and an ozone monitoring instrument during 1979–2008. In the region, total ozone exhibits seasonality ...
Water vapour characteristics and radiative effects at high-altitude Himalayan sites

Dumka, U. C; Kaskaoutis, D. G; Khatri, Pradeep; Shantikumar, N. S; Sheoran, Rahul; Jade, Sridevi; Shrungeshwara, T. S; Rupakheti, Maheswar (Elsevier B.V., 2022-02)

We analyze long-term aerosol and precipitable water vapour (PWV) properties at two high-altitude sites (Nainital and Hanle) over the central Himalayan and western Trans-Himalayan region from 2008 to 2018. First-time ...
