Our long awaited publication exploring the Descending Cirrus clouds over Gadanki. Int'l. Journal of Remote Sensing It is the story of Cirrus clouds which descends / ascends altitude ..... their characteristic properties ....using NARL's long term Lidar data. Nellore Manoj Kumar, Kannan Venkatramanan, Anish Kumar M. Nair & Shekatam Satheesh Kumar   (2020)   On the characterization of descending nature of cirrus clouds over a tropical site, Gadanki,   International Journal of Remote Sensing,   41:17,   6550-6569,   DOI:  10.1080/01431161.2020.1742942 https://t.co/vpReYZZZsY https://t.co/3zJDq2KNjM https://www.tandfonline.com/doi/abs/10.1080/01431161.2020.1742942 The interesting feature of Cirrus cloud's descending & ascending are well characterized using ~6 years of lidar observations. The study roots back to the inspiration from my earlier work published in J.Geophysicsl Research in 2012 Nair,  A. K. M.   ,  K....

Our paper published in the Atmospheric Science Letters on different types of clouds during monsoon phases.

Nasa is gearing up to have 5 consecutive launches of sounding rockets which would releasr Tri-Methyl-Aluminum higher in the sky which would be acting like tracers in the Jet Stream. It would be tracked by the ground based cameras. A similar experiment was done by ISRO in Jan 2010 during the annular solar eclipse.   Read more: http://www.nasa.gov/mission_pages/sunearth/missions/atrex-nightlight.html

Parameswaran For full paper, click this link:  http://dx.doi.org/10.1016/j.jastp.2011.10.012 , Abstract Impact of the long duration noontime annular solar eclipse on 15 January 2010 on the vertical distribution of aerosols and mixing layer height ( H M ) in a well-developed convective atmospheric boundary layer (ABL) has been investigated using continuous Lidar observations over a tropical coastal station, Thumba (8.5°N, 76.9°E). This study shows that  H M  has decreased from its peak value of ∼1800 m at 12:00 h to ∼1000 m following the annular phase of the eclipse (13:17 h), whil...

Why should humans go to Space ........?                                 Exploration is the inquisite nature of human mind, which has historically led to the discovery of new continents and development of new habitats. Looking back, without these discoveries and advances, living on Earth would have been completely different from what we see today. Rapid developments in human race, limitations in resources on Earth, and the potential threat from weapons of mass destruction necessitates that we will have to boldly go far beyond the Earth's boundaries if the human race has to continue for thousands of years forward. More importantly, space explorations hold the key to unravel the secrets behind the origin and evolution of life and environment surrounding us. These drive the quest for space exploration and colonization. Where else can earthlings colonize?               ...
