Detection of Atmospheric Nh3 From Iasi Satellite and its Validation using Chemical Transport Model Over Indian Region: A Review
Journal Title: International Journal of Environment, Ecology, Family and Urban Studies (IJEEFUS) - Year 2017, Vol 7, Issue 1
Abstract
Atmospheric ammonia (NH3 ) has great environmental implications due to its important role in ecosystem and global nitrogen cycle, as well as contribution to secondary particle formation. Ammonia (NH3 ) emissions in the atmosphere have increased substantially over the past decades, largely because of intensive use of fertilizers. It has been increasing over a South Asia and particularly in India and China. It has a negative impact to the environment and the public health. Measurement of NH3 distribution lies generally on model calculation, due to the limited availability of ground-based measurements. Gaseous ammonia NH3 is the most abundant alkaline gas present in the atmosphere. It also contributes to the total reactive nitrogen. The objective of this study is to determine the NH3 emission and its distribution over India and China. This study will give the hotspot areas of NH3 emissions over India and China. Study will also include temporal and spatial analysis of NH3 measurement which will give season wise distribution of ammonia over an Indian region and will highlight which season is particularly contributing more to its concentration. There are various sources which contribute to the emission of ammonia. This study will discuss source contribution for ammonia emission. Particularly five different sectors/sources have been considered for the emissions. This includes agricultural, industrial, residential, transport and energy sectors. Hence, by analysing this results the prominent source which contributes to the emissions can be highlighted.
