    Neeharika, V; Bagare, S. P; Shantikumar, N. S; Rajendra, B. S (Elsevier B. V., 2010-01)
    A Skyradiometer was installed at Hanle in Ladakh, in October 2007 as a part of the site characterization program for the proposed National Large Solar Telescope project. Aerosol optical depth (AOD), single scattering albedo ...
  • Aerosol radiative forcing over a high-altitude station Merak, in the trans-Himalayan region during advection of anthropogenic events from the Indo-Gangetic Plain 
    Shantikumar, N. S; Bagare, S. P; Srivastava, A. K; Sohn, B. J; Song, H.-J; Larson, E (Elsevier B.V, 2014-12)
    Advection of anthropogenic aerosols from the Indo-Gangetic Plain (IGP) and dust aerosols from distant deserts towards a high-altitude station Merak, in the trans-Himalayan region are reported during June–July 2011. In order ...
  • After the fall: from Adam and Eve to apples and elevators 
    Vishveshwara, C. V (Inter-University Center for Astronomy and Astrophysics, 1998)
  • After the moon, ISRO eyes the sun (IIA in NDTV News) 
    NDTV (NDTV, 2011-06-09)
    The Indian Space Research Organisation is now putting together its first dedicated mission to study the sun, aptly called Aditya-1. NDTV travelled to ISRO's labs to get you this exclusive.

  • Age aspects of habitability 
    Safonova, M; Murthy, J; Shchekinov, Yu. A (Cambridge University Press, 2016-04)
    A ‘habitable zone’ of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for habitable planets is whether they host ...
