GLANCE

Prime company: BELGIAN INSTITUTE OF SPACE AERONOMY (BIRA-IASB) (BE)

Prompted by the novel satellite data of glyoxal (CHOCHO) and formaldehyde (HCHO) retrieved by the high resolution spectra of the TROPOMI sounder, GLANCE aims to assess the global budget of their precursors using the MAGRITTEv1.1 global atmospheric chemistry-transport model (CTM) and an inverse adjoint-based framework. Both compounds are formed in the oxidation of non-methane volatile …

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 …

IMPALA

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 …

KARLOS

Prime company: LUFTBLICK OG (AT)

Air pollution is one of the current major environmental issues affecting human health at the global scale, therefore monitoring air pollution in urban and suburban areas is of great societal importance. The monitoring of air quality at urban scales is currently based on telemetric in-situ networks, which provide continuous observations with high accuracy of a …

Development and interpretation of improved Nitrous Acid Retrievals project – DINAR

Prime company: BELGIAN INSTITUTE OF SPACE AERONOMY (BIRA-IASB) (BE)

The importance of nitrous acid (HONO) in atmospheric chemistry stems from its role as precursor of the OH radical.The latter is among the most important oxidizing molecules and controls the degradation of pollutants and greenhouse gases, and contributes to ozone formation and photochemical smog. Accurate representation of HONO sources is highly relevant to the modeling …

EOplumes

Prime company: UNIVERSITY OF EDINBURGH (GB)

The detection of trace gas plumes allows us to improve attribution of pollutant emissions and photochemical processing in the global troposphere. Data collected by the ESA TROPOspheric Monitoring Instrument (TROPOMI) has resulted in a growing number of case studies that have used ad hoc methods to detect plumes for science applications. Developing a more comprehensive …

Ozone Recovery from Merged Observational Data and Model Analysis (OREGANO)

Prime company: UNIVERSITY OF BREMEN (DE)

Stratospheric ozone (the “ozone layer”) protects the biosphere from harmful UltraViolet (UV) radiation. Ozone (O3) is expected to recover as a consequence of the Montreal Protocol signed in 1987 and its Amendments regulating the phase-out of ozone-depleting substances (ODS). The stratospheric halogen amount (mainly bromine and chlorine) released by ODSs reached its maximum abundance in …

Looking at aerosol properties in cloudy environments

Observing and understanding aerosol properties is fundamental for the remote sensing community, yet things get more complicated in cloudy environments. Pixels located in the transition zone between pure cloud and pure aerosol are often discarded by both aerosol and cloud algorithms, despite being essential for studying aerosol–cloud interactions, which still represent the largest source of …

New aerosol and surface properties estimation from Sentinel-5P TROPOMI

A high level of innovation in algorithm development and methodological approach is the key feature of the activities performed during the ESA S5P+Innovation AOD/BRDF project. Aerosol Optical Depth (AOD) is the single most comprehensive variable for the remote assessment of the aerosol load in the atmosphere. Atmospheric aerosols, such as aerosols from the burning of …
