I myself Dr. R. K. Nayak, a scientist from National Remote Sensing Centre (NRSC,Hyderabad) of Indian Space Research Organization (ISRO) working on the problem of regional carbon cycling over India and surrounding under the National Carbon Project (NCP) hosted by ISRO-Geosphere Biosphere Program since 2007 under the leadership of Dr. V. K. Dadhwal.

Under the project, extensive ground base observation of several parameters characterizing the regional C cycle which includes biomass, soil map, surface CO2 sensing, biosphere-atmosphere CO2 flux exchanges (through flux towers etc) are measured since the project started in 2007. My responsibility in the project to carryout modeling study (forward/inverse) of atmospheric CO2 over India. We have made some progress towards understanding the terrestrial source and sink pattern of atmosphere CO2 by simulating NPP and NEP over India by using ground and remote sensing data in NASA-CASA model. Seasonal and inter-annual variability and their climate control over India were examined (published in Int. J. climatology and Env. Mon. Assessment).

I have received Master Degree in Physics from Utkal University in 1999 and PhD in Physics from Goa University in 2006. I have worked under the Guidance of Dr. S. R. Shetye, Director of National Institute of Oceanography on the PhD topic "Coupling between the north Indian Ocean and Monsoon: thermal cycling of the upper ocean of the Arabian Sea". I also worked on the "Modeling the tidal coastal circulation in the coastal oceans" and "Study on Meso-scale Oceanography Processes on the tropical Indian Ocean". I served as a teaching faculty at "Indian Institute of Remote Sensing (IIRS/ISRO), Dehradun" during 2005-2010. My teaching interest at IIRS includes "satellite oceanography", "Geophysical Fluid Dynamics", "Linear Algebra and Differential Calculus".
