The phrase "atmospheric sources" is correct and usable in written English.
It can be used when discussing origins or contributors of substances or phenomena related to the atmosphere, such as pollution or weather patterns.
Example: "The study focused on identifying atmospheric sources of greenhouse gases that contribute to climate change."
Alternatives: "airborne sources" or "environmental sources".
87Sr/86Sr ratios were employed to discriminate contributions from mineral weathering and atmospheric sources.
Gibb's plots confirm that the water chemistry in the area was mostly controlled by weathering of rocks with a minor contribution from atmospheric sources.
Factor 2 is a pH factor due mainly to contributions from humic acid, poor waste management and pollution in from atmospheric sources especially, for nitrate (Jeong 2001).
Unlike nitrogen (N), P cannot be fixed from atmospheric sources; it can only be obtained by uptake from soil via plant roots as orthophosphate (HPO4 2− or H2PO4 − depending on soil pH) [3].
Measurement of the isotopic compositions of carbon dioxide and methane is a powerful tool for quantifying their atmospheric sources and sinks, which is especially important considering the dramatic increase in these greenhouse gases during the industrial era.
Local nutrient recycling was assessed at the district scale through: (i) the local supply, defined as the ratio of the amount of nutrients from exchanges among farms plus the amount of nitrogen from atmospheric sources, to the sum of inputs to organic farms; and (ii) the cycling index, defined as the fraction of nutrients flowing at least twice through the same farms.
Atmospheric source terms in different fission product removal processes are also calculated and compared.
Besides, three reactor core damage assessment methods are integrated into atmospheric source term estimation.
The development of rapid atmospheric source term estimation system (RASTES) for AP1000 nuclear power plant (NPP) is described.
Alternatively, carbonate minerals dissolved by sulfuric and nitric acids may represent an atmospheric source of CO2 with no rapid balancing atmospheric sink.
These adjustments enable the system to be more flexible and realistic in atmospheric source term estimation, and more applicable to AP1000 NPP.
