Scientific Statement... Dr. Gufran Beig has identified important anthropogenic climate change signal in the upper atmosphere and made reliable estimate of role of atmospheric chemistry on regional climate change. Careful separation of natural variability from climate change signal by the Nominee unraveled a significant anthropogenic cooling trend in the upper atmosphere resulting in shrinking of the ionosphere with significant potential influence on radio propagation and navigation systems. Further, he used coupled 3-D chemistry-climate model to quantifying reliably the role of atmospheric chemistry on regional climate change of the lower and middle atmosphere. In this context, gridded emission inventory of several pollutants for India along with their decadal growth have been constructed and resulted radiative forcing estimated.. |
