Variability of atmospheric ammonia and its sources over Indian region
The Indo-Gangetic Plains (IGP) in India is one of the largest NH3 emission hotspots of the world.
- Atmospheric NH3 is challenging to measure because of its high reactivity, solubility, and its stickiness to the measuring instruments.
- Continuous development in satellite observations have provided great insights on spatial variability. But temporal coverage is better only with ground observations.
- Indian monitoring body(CPCB), has started monitoring multiple pollutants including gaseous NH3 across Indian region. Present study, shows the spatial and temporal variability of NH3 across Indian region using CPCB data.
