In this paper, we evaluate the performance of the chemical transport model ‘CHIMERE’ over large Indian region (4–37.5°N; 67–88.5°E) for multiple years (2006, 2007 and 2008) by comparing the model simulations with concurrent aerosol measurements from different locations. Model simulated nearsurface black carbon mass concentrations agreed satisfactorily with measurements at various locations (oceanic, inland and island sites), in general, except during monsoon months, when the model underpredicted the measurements.

In order to understand the regional climate implications of aerosols over Indo Gangetic Plains (IGP), a major Indo-US field experiment, Ganges Valley Aerosol Experiment (GVAX) was conducted during 2011– 12. Atmospheric Radiation Measurement (ARM) mobile facility (AMF) was deployed at the northern Indo-Gangetic Plain over the high-altitude site, Manora Peak, Nainital (29°21′33.84″N, 79°27′29.27″E, 1980 m amsl) in Central Himalayas, for an year-round measurement of aerosols, clouds and other climate-relevant atmospheric parameters.

Yam has several nutritional benefits, yet the crop remains neglected and underutilized. In the absence of national research and extension programmes on yam, LIBIRD’s initiative to promote yam cultivation on terrace walls has caught up with the Chepang communities in Nepal.
