Modelling effects of acid deposition and climate change on soil and run-off chemistry at Risdalsheia, Norway [PDF]
Elevated carbon dioxide levels, caused by anthropogenic emissions of carbon dioxide to the atmosphere, and higher temperature may lead to increased plant growth and uptake of nitrogen, but increased temperature may lead to increased nitrogen ...

Analysis and Forecasting of Air Pollution on Nitrogen Dioxide and Sulfur Dioxide Using Deep Learning
When Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) mix, they cause pulmonary fibrosis, and severe public health issues. Therefore, introducing deep learning models to predict changes in Nitrogen Dioxide and Sulfur Dioxide air pollution can enable the ...
