摘要:In this study, high-frequency, multilevel measurements, performed from late October to mid-November of 2015 at a 80 m tall tower of the Amazon Tall Tower Observatory (ATTO) project in the central state of Amazonas, Brazil, were used to diagnose the evolution of thermodynam...

摘要:Iron is the most abundant transition element in airborne particulate matter (PM), primarilyexisting as Fe(II) or Fe(III). Generally, the fraction of water-soluble ironis greater in urban areas compared to areas dominated by crustal emissions.To better understand the origin o...

摘要:The Po Valley (Italy) is a well-known air quality hotspot characterized byparticulate matter (PM) levels well above the limit set by the European AirQuality Directive and by the World Health Organization, especially duringthe colder season. In the framework of Emilia-Romagna...

摘要:The top-of-atmosphere (TOA) outgoing longwave flux over the 9.6  µm ozone band is a fundamental quantity for understanding chemistry–climatecoupling. However, observed TOA fluxes are hard to estimate as they exhibitconsiderable variability in space and time that depen...

摘要:Clouds are highly variable in time and space, affecting climate sensitivity andclimate change. To study and distinguish the different influences of clouds onthe climate system, it is useful to separate clouds into individual cloudregimes. In this work we present a new cloud class...

摘要:Finding observational evidence of land surface and atmosphere interactions is crucial for understanding the spatial and temporal evolution of the boundary layer, as well as for model evaluation, and in particular for large-eddy simulation (LES) models. In this study, the inf...

摘要:Open biomass burning (OBB) has a high potential totrigger local and regional severe haze with elevated fine particulatematter (PM 2.5 ) concentrations and could thus deteriorate ambient airquality and threaten human health. Open crop straw burning (OCSB), as acrit...

摘要:Satellite observations of tropospheric NO2 columnsare extensively used to infer trends in anthropogenic emissions of nitrogenoxides (NO x ≡ NO + NO2), but this may be complicated bytrends in NO x lifetime. Here we use 2004–2018 o...

摘要:Long-term trends of wet deposition of inorganic ions areaffected by multiple factors, among which emission changes and climateconditions are dominant ones. To assess the effectiveness of emissionreductions on the wet deposition of pollutants of interest, contributionsfrom these f...
