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....

When Cirrus descends .......

Have you heard of Cirrus cloud descending .........? What is it ......? Is it a frequent phenomenon .....? Does it have seasonal dependence ....? Where does it occur ......? Why do cirrus descend .....? What is it's impact .......? We have discovered the phenomenon using 3 years of lidar observations over Thiruvananthapuram, near southern tip of India that Cirrus clouds frequently DESCEND.....! After analysing the data together with other observations and models, we have come up answers to the above questions.  The observations and results are now accepted by the scientific community and it finds a place in the Journal of Geophysical Research - JGR (Atmosphere).

Equinox & Solstice (view from Space).  Doesn't it convey better information than the usual cartoons.....?  I have taken the Satellite images from Meteosat via. Dundee satellite Receiving Station and made the matrix using GIMP.

Clouds Descending .....?

Earth’s clouds descended a little — about one percent on average — during last decade, finds a new NASA-funded university study based on NASA satellite data.  The results have potential implications for future global climate. Decreasing global cloud heights suggest negative feedback over the last decade Data from NASA's MISR instrument on NASA's Terra spacecraft show that global average cloud height declined by about 1 percent over the decade from 2000 to 2010, or around 100 to 130 feet (30 to 40 meters). (Image credit: University of Auckland/NASA JPL-Caltech) The study was recently published in GRL.
