While sudden stratospheric warming (SSW) events are more common in the Northern Hemisphere, Safieddine et al. (2020) investigated the rare SSW event in the Southern Hemisphere that occurred in 2019 […]
The Paris megacity faces frequent fine particulate matter (PM2.5) pollution episodes in spring. At this period of the year, large numbers of the particles consist of ammonium sulfate and nitrate […]
Formic (HCOOH) and acetic (CH3COOH) acids are the most abundant carboxylic acids in the Earth’s atmosphere and contribute to the acidity of rainwater and cloud. Current knowledge is however unable […]
A high-resolution map (~1km²) of the global atmospheric distribution of ammonia was generated combining almost a decade of IASI measurements (Van Damme et al., 2018). From it, they identify, categorize […]
The photochemical production of lowermost tropospheric ozone (located below 3 km of altitude) was quantified for the first time only using satellite data (Cuesta et al., 2018). This is the […]
Wespes et al. (2018) present the global fingerprints of recent changes in the tropospheric O3 levels measured by IASI over 2008 – 2017. Using appropriate multivariate regression methods, we discriminate […]
A study by Wespes et al. (2017) presents global patterns of the main geophysical drivers of IASI O3 variations, obtained by applying appropriate annual and seasonal multivariate regression models on […]
δD (isotopic ratio of HDO to H2O) observations derived from IASI measurements above the North Atlantic reveal the influence of the surface heating over Sahara in controlling the humidity budget […]
A recent study by Whitburn et al. (2017) investigates the spatial and temporal variability in the biome-specific NH3 enhancement ratios relative to CO (ER_NH3/CO). They suggest a revision of the […]
