Nitric Acid in Firn: Discussion,here. There are, in fact, several reports of apparent HNO. loss from near-surface snow; though a quantitative understanding of the loss processes has yet to emerge. The following discussion highlights the points raised at the meeting regarding the loss processes, and offers a conceptual picture of what we think we need to understand.作者: JECT 時間: 2025-3-22 12:07
Impact of Biomass Burning on the Atmosphere,matic impacts of blomass burning on the atmosphere throughout the last century, specifically looking at the cycles of carbon, nitrogen, and sulfur.
