Sukanta Sau

I have completed by Bachelors degree in Physics in 2007 and Masters degree in Atmospheric Science in 2009 from the University of Calcutta, India. I joined as a research scholar in Equatorial Geophysical Research Laboratory, Indian institute of Geomagnetism, Tirunelveli, India in 2011 and obtained my PhD degree in Physics in 2019. I have worked as a research associate in Indian institute of Geomagnetism, Navi Mumbai, India between August 2018 and August 2020. I joined the Arecibo Observatory as a postdoctoral researcher in October 2020.

During my PhD tenure, I have mainly utilized all sky airglow images and ionosonde data obtained from the low latitude Indian region to study different upper atmospheric phenomena. They include waves in the lower ionosphere, generation and evolution of equatorial plasma bubbles (EPBs) under quite and disturbed geomagnetic conditions. I have also utilized photometer data to study waves and coupling processes in the low latitude Mesosphere Lower Thermosphere (MLT) region.

At present, I am using passive and active optical instruments to study dynamics of the Mesosphere-Lower Thermosphere (MLT) region.

At present, I am working in a project that utilizes large passive optics data base available at Arecibo Observatory to study long term trends in the upper atmosphere.
