Kesyon kle: 1) Ki kapab chofè prensipal yo nan noks emisyon nèj dwe paramètres nan modèl nimerik? 2) Ki sa ki se repons lan nan atmosferik kapasite konburant chanjman nan azòt chimi nèj akòz chanjman nan klima modèn? 3) Sa gen tandans yo nan polè nivo noks atmosferik ak kapasite konburant sou dènye syèk la?

Key questions: 1) How can the main drivers of NOx snow emissions be parameterized in numerical models? 2) What is the response of atmospheric oxidising capacity to changes in nitrogen snow chemistry due to modern climate change? 3) What are the trends of polar atmospheric NOx levels and oxidising capacity over the last century?
