| description | The monsoon based climate system, diverse land use and land cover distribution and cultural practices poses complex issues in
monitoring, assessment and simulation of Indian carbon cycle. Several studies reported lack of spatially and temporally consistent
databases, need for calibration and validation of models, and development of national frame work to maintain consistency and
completeness in efforts and reduction of uncertainty. Considering the need, as part of ISRO Geosphere Biosphere Programme, National
Carbon Project (NCP) initiative was taken up to understand and assess land, atmosphere and oceanic components of carbon cycle with a
significant scope for integration of remote sensing, geospatial and process based models. The results from the initial studies are discussed
in the paper. An increase of the country's forest carbon stocks from 6244.8 to 6621.6 Mt with an annual increment of 37.7 Mt of the
carbon from 1995 to 2005 is reported. In the national scale, CASA model based average annual NPP is estimated to be 1.5 Pg C Yr<sup>-1</sup> and
is increasing at the rate of 0.005 Pg C Yr<sup>-2</sup> during past 25 years from 1981–2006. Analysis of Mid tropospheric CO<sub>2</sub> levels retrieved from
AIRS data since 2002 till now revealed increasing rate of CO<sub>2</sub> at 2.14 ppmv yr<sup>-1</sup>. It was also o found that biosphere uptake over India and
oceanic uptake over the south Indian Ocean could play positive role on the control of seasonal variability of atmospheric carbon dioxide
growth rate The paper presents further details on different sub components, recent results and challenges ahead of the project. |
