Welcome to the Centre for Atmospheric Studies (CAS). CAS was established in the year 2006 to invigorate the decades long space science research programme in this university and now is one of the constituents of the School of Earth, Atmospheric Science, Energy and Environment. Our primary focus is research in the area of climate change and climate variability and its impact on the Environment (or Biosphere and Geosphere). We have a robust observational programme of aerosol and trace gases thanks to generous support from the Indian Space Research Organisation and the University Grants Commission.
Space weather is another area of prime focus in the Centre and we currently operate a chain of GNSS receivers in NE India and the only Ionosonde now operational since 2010 in whole of east and north east India. The ISRO and the DST support space research in CAS. We have also undertaken the task of development of an Indigenous Ionosonde in collaboration with SAMEER, IIT Mumbai with financial support from DEITY.
CAS, Dibrugarh University is one of the eight participating Centre/institutions in India for its Space Science Promotion Scheme since 2009. Student fellowships are awarded to two selected M. Sc. Physics students each year under this programme. Majority of the student fellows have opted to pursue research in Atmospheric Science in the Centre and are either pursuing or have graduated with Ph. D degrees.
We undertake collaborative research programme with national and international institutions and faculties from these institutions are supervising Ph. D students in the Centre. Currently 12 researchers are involved under various projects, including a DST INSPIRE fellow.
We publish in all prestigious atmospheric and space science journals and the total citation index has crossed the 1K mark.
Numbers of CAS alumnus now occupy senior positions in ISRO and CSIR laboratories. A young faculty has recently bagged the prestigious Associateship of the ICTP, Italy and a Ph. D. scholar has been awarded the Fulbright-Kalam Climate research fellowship in the inaugural year. Another student has completed a tenure at the ICIMOD, Kathmandu.

T. Subba, Ph. D. scholar under the joint supervision of Prof. P K Bhuyan in the Centre for Atmospheric Studies, Dibrugarh University and Dr. Mukunda M Gogoi, Scientist SE in the Vikram Sarabhai Space Centre, Trivandrum has been selected for the Fulbright-Kalam Climate Fellowship, 2017-2018 for Doctoral research. She is among three scholars from India to bag the fellowship in its inaugural year. The US-India Climate Fellowship programme named ‘Fulbright-Kalam Climate Fellowship’ to build long term capacity to address Climate Change related issues in both the countries was launched in pursuance of the Joint Statement made by the President of the United States of America and the Prime Minister of India in September 2014. Ms Subba will pursue her research in either Penn State, Washington University or Washington State University in the academic session 2017-18 as part of her current Doctoral programme in Dibrugarh University. Her work in the United States will basically be focused on the quantification of complex climate forcing due to aerosols and their impact on climate change.
