Variability of atmospheric ammonia and its sources over Indian region

by Alexander Sedov | May 20, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

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...

Reactive Nitrogen Flows Between Sector Energy and Transport and the Atmosphere

by Alexander Sedov | May 17, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Reactive Nitrogen Flows Between Sector Energy and Transport and the Atmosphere The Convention on Long-range Transboundary Air Pollution (CLRTAP) approach has been used to calculate nitrogen fluxes in the energy and transport sectors. Air pollutants arise from energy...

Impact of climate change on nitric oxide and nitrous oxide emission

by Alexander Sedov | May 17, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Impact of climate change on nitric oxide and nitrous oxide emission The impact of soil type, land use and climate on emission rates of nitric oxide (NO), a precursor of atmospheric ozone (O3), andN2O, a powerful GHG, as well as ratios of N2O:NO are still not well...

Oxygen regulates nitrous production directly in agricultural soils

by Alexander Sedov | May 17, 2021 | Posters for INI2021, Posters for INI2021 – 5b. Biogeochemical N Cycle

Oxygen regulates nitrous production directly in agricultural soils Soil oxygen is the key proximal factor simultaneously controlling nitrification and denitrification at the cellurar-level, and further determining the partitioning of the end products between...
