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 time series of spatially gridded averaged O3. They show that the models are able to explain most of the O3 variability captured by IASI and […]

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 above the Atlantic Lacour et al. (2017). The added information contained in the isotopic ratio of water vapour allows to clearly distinguish between three different […]

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 ER_NH3/CO and emission factors for NH3 used in the bottom-up fire models and highlight the need for the development of dynamic ER_NH3/CO in order to […]

Van Damme et al. (2017) just published a paper presenting an improved version (v2.1) of the neural-network-based algorithm for retrieving atmospheric ammonia (NH3) columns from IASI satellite observations. Two datasets using different input data for the retrieval are described: one is based on the operationally provided EUMETSAT Level 2 (ANNI-NH3-v2.1), and the other uses the […]
