With this ITT ESA aims at developing a platform to support coordinated access and exploitation of EO-based information services by the Governments stakeholders in the Southern Baltic Countries (Estonia, Latvia, Lithuania). The platform shall integrate a priority set of services addressing the needs of public sector stakeholders and build on regional cooperation, stimulate regional uptake …
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 …
This activity implements and validates SR algorithms for hyperspectral imagery (HSI). With respect to the input data presented for reconstruction, these considered algorithms will be either 1) fusing of HSI (PRISMA) with an auxiliary panchromatic image of higher spatial resolution; or 2) fusing of a HSI without any additional data, exploiting the spatial-spectral fusion of …
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 …
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 …
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 …
It has become abundantly clear during the COVID-19 pandemic that environmental factors can be important in the emergence, spread, health impact, social political response, and socioeconomic recovery plan from Sars-Cov-2/COVID-19. Having tools available to study the impact of the environment for this pandemic and future pandemics is important to increase preparedness and curtail future societal …
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 …
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 …
Pollutant and greenhouse gas emission inventories provide essential information for policy makers, governments and subsidiary bodies to evaluate progress towards emission abatement measures, and decide on future strategies. Inventories use different methodologies between countries, and have large uncertainties related to both activity data and emission factors. The use of satellite data, notably the imagery of …
