Academic Programs


In the last two decades, important knowledge has emerged about the present climate of the earth and its dramatic changes in the past. Indeed, new observations from field experiments, satellites and ocean buoys, together with theoretical calculations and powerful computer models, have helped in understanding complexities of the climate. In light of this complexity, there are several fundamental open questions, and quite surely, new discoveries on the horizon. With increasing demand for more accurate weather and climate forecasts, the prospects for young researchers are bright. The challenges of understanding and prediction of climate are multidisciplinary, we welcome science and engineering graduates to join us in this exciting endeavour.

Based on the expertise of the CAOS faculty, specific areas of study include aerosols and their impact on the climate, atmosphere-ocean-climate modeling, carbon cycle modeling, cloud physics, geophysical fluid dynamics, monsoon variability and prediction, physical-chemical-biological oceanography, spatio-temporal scaling in geophysical data, and tropical convection.

Career Opportunities

Several univerisities and government organizations such as the Ministry of Earth Science, the Indian Space Research Organization, the Council for Scientific and Industrial Research and the Armed Forces require scientists trained in atmospheric and oceanic sciences. Further, as the economy has grown, there has been an increase in industrial applications of weather and climate information. Prominent sectors among these are : the agriculture industry, aviation, energy resources, insurance & financial services, oil & gas exploration and risk management. We expect this demand from the private sector to grow in the coming years.

CAOS alumni have gone on to work and/or study in reputed institutions within India and abroad. This includes ISRO, the National Aerospace Laboratory, IITM-Pune, INCOIS-Hyderabad, CDAC, TCS, TERI, Siemens, Intel and numerous universities and research labs in the US, Japan and the European Union. Details of our alumni placement can be found here.

The graduate academic programs

  • Master of Technology (M.Tech.) in Climate Science : This program is designed for students with a Bachelor's degree from any branch of Engineering, or Master of Science in the Physical Sciences. This is a two year program which consists of course work and a project. It is intended to provide a sound foundation in the theory of the atmosphere-ocean-climate system, and to develop skills in computational, data analysis and observational techniques. Details of the background, admission procedure, course content and career opportunities associated with this program are outlined here, the information can also be downloaded here.
  • Master of Science (M.Sc.) Engineering (by research) : This program is designed for students with bachelors degree in any branch of Engineering, or a Master of Science degree in any branch of science (with exposure to Mathematics either at undergraduate or postgraduate level). Students are selected based on an interview if they have passed a national examination such as GATE, UGC-CSIR NET or the entrance test conducted by the Indian Institute of Science. The program's intended duration is two to two-and-a-half years. Candidates are required to successfully take 4-6 courses followed by research work that culminates in a thesis. On completion of the M.Sc. students may choose to continue for a Ph.D. at the Centre.
  • Doctor of Philosophy (Ph.D.) : Requirements : ME / M Tech or BE / B Tech or equivalent degree in any branch of engineering including Atmospheric Sciences or M Sc or equivalent degree in Physics, Mathematics, Atmospheric Sciences, Oceanic Sciences. Candidates should have taken a course/paper in mathematics involving differential equations” at graduateor postgraduate level. Those having BE/ B Tech or MSc degree need to pass a national level examination (GATE, CSIR-UGC, entrance test conducted by IISc, etc) to be called for interview.
