2010年1月20日至2月15日，在巴黎周围的SIRTA观测站，在MEGAPOLI（大城市：排放、城市、区域和全球大气污染和气候影响，以及评估和缓解的综合工具）冬季实地活动期间进行了亚硝酸测量。在活动结束时，发生了重大降雪事件，导致最后几天在采样点积雪。这些具体条件使我们有机会在地面有雪和没有雪的情况下审查HONO的预算。当场地被雪覆盖时，发现HONO源要高得多。这为中纬度污染地区存在大量积雪的HONO源提供了证据，需要进行调查，以便更好地了解冬季光化学。
Nitrous acid measurements were carried out during the MEGAPOLI (Megacities: Emissions, urban, regional and Global Atmospheric POLlution and climate effects, and Integrated tools for assessment and mitigation) winter field campaign at the SIRTA observatory in Paris surroundings from the 20th of January to the 15th of February 2010. At the end of the campaign, significant snow events occurred leading to snow accumulation at the sampling site during the last days. These specific conditions gave the opportunity to examine the HONO budget with and without the presence of snow at ground. Much higher HONO sources were found for the days when the site was covered by snow. This provides evidence for the existence of a large snowpack source of HONO in mid-latitude polluted regions that needs to be investigated for a better understanding of wintertime photochemistry.
