Prime company: NATIONAL OBSERVATORY OF ATHENS (GR)

ESA wind mission Aeolus hosts the first space-based Doppler Wind Lidar (DWL) world-wide. Its scientific objectives are to improve Numerical Weather Predictions (NWP) and to advance the understanding of atmospheric dynamics and its interaction with the atmospheric energy and water cycle. The primary data product is profiles of horizontally projected line-of-sight winds from the surface …

Is there an ozone hole over the tropics?

Certainly not according to available data. The claim of a so called “ozone hole” in the tropical lower stratosphere, “seven times larger in area than the one over Antarctica” (see Fig. 1), was made by a – highly controversial – paper (Lu, 2022). The study used data from the smoothed and gap-filled version of the …

Building a bridge: estimating carbon dioxide emissions using satellites

A team of researchers estimated the carbon dioxide (CO2) emissions from coal-fired power plants and other major anthropogenic point sources in the South African Highveld region using space-based data. The results indicate that CO2 emissions can be obtained also in challenging cases where the plumes from multiple sources overlap. The new publication characterizes CO2 emissions …

Prime company: KNMI (NL)

Methane is among the most important greenhouse gases in the Earth’s atmosphere, causing rapid global warming. A recent study indicates that tropical methane emissions explain a large fraction of the global atmospheric methane growth (Feng et al., 2022). The relatively short lifetime of methane of about a decade makes methane emissions an attractive target of …

Synergetic retrieval from multi-mission space-borne measurements for enhancement of aerosol characterization (SYREMIS)

Prime company: GRASP-SAS (FR)

Atmospheric aerosol is one of the main drivers of climate changes. Importance of accurate global aerosol characterization for climate studies and air pollution monitoring is a well recognized problem (e.g., see IPCC AR5 by Boucher et al.2013). In addition to the traditional spectral Aerosol Optical Depth (AOD) such characterization should also include such extended aerosol …
