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 …

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 …

Synergetic Retrieval from GROund based and SATellite measurements for surface characterization and validation (GROSAT)

Prime company: GRASP-SAS (FR)

Reflectance of the Earth surface is one of the natural major components affecting climate. Surface interaction with incoming solar radiation and the atmosphere has a substantial impact on the Earth’s energy budget. Moreover, the accurate description of the surface reflection is crucial for different atmospheric studies including aerosol and trace gases characterization.   One of …

Understand and mitigate impacts of 3D clouds on UV-VIS NO2 trace gas retrievals by AI exploration of synthetic and real data (MIT3D)

Prime company: NILU – NORWEGIAN INSTITUTE FOR AIR RESEARCH (NO)

Operational retrievals of trace gas column amounts assume (near) cloud free conditions.  However, the large pixel size of the satellite instruments (for example the TROPOspheric Monitoring Instrument on Sentinel 5P, TROPOMI-S5P, is 5.5 km by 3.5 km at nadir) imply  that pixels may be contaminated by sub-pixel sized cloud(s). Furthermore, clouds in neighbour pixels may …

Water cycle changes characterised from atmospheric moisture recycling (WEATHER)

Prime company: UNIVERSITY OF LEICESTER (GB)

Living Planet Fellowship research project carried out by Tim Trent. Water vapour is an essential greenhouse gas in the Earth climate system, acting as a natural feedback mechanism for carbon dioxide forcing. Critical to the development of cloud and precipitation, water vapour also has a significant influence and impact on surface fluxes and radiative balance. Water vapour …

Carbon dioxide emission plumes from a large power station detected from space

Researchers at the Finnish Meteorological Institute developed a new methodology to derive source-specific NOₓ-to-CO₂ emission ratios using satellite observations. The method was applied to Matimba power station in South-Africa. The results can be used to estimate carbon dioxide emissions. Missions to observe CO2 plumes Since the Paris agreement was adopted in 2015, the role of …

SEN4CARBON Theme 2: Fire Dynamics (SENSE4FIRE)

Prime company: TECHNISCHE UNIVERSITAT DRESDEN (DE)

Based on the new possibilities of the Sentinel series of satellites, this project aims to develop a highly novel approach to derive global fire emissions estimates based on the characterisation of individual fires and their behaviour. These data will be combined with bottom-up estimates of fuel and combustion and top-down constraints on total carbon emissions …

SEN4CARBON Theme 1: Terrestrial Gross Primary Production (SEN4GPP)

Prime company: NOVELTIS SAS (FR)

The objective of the Sen4GPP project is to assess time-space variability of terrestrial gross primary production  (GPP) of terrestrial ecosystems by a synergistic exploitation of the complementary information provided by  the Sentinel missions (Sentinel-2, Sentinel-3 and Sentinel-5P) at multiple spatial and temporal resolutions, as well as other Earth Observation and in situ data.

AlpAirEO – Earth Observation for Air Quality and Health – Alps regional initiative

Prime company: DLR – GERMAN AEROSPACE CENTER (DE)

Recently, the European Environmental Agency (EEA) reported that air pollution contributed to 400.000 annual deaths in the EU. The Alps are special. They host 14 million people and attract many tourists and businesses. Due to the diverse landscape and climate, pollution hotspots can develop in certain areas while pristine environments prevail throughout most of the high …

PRISMA + S5P demonstration for COVID-19 studies

Prime company: GRASP-SAS (FR)

Recent climate remote study showed essential effect of COVID-19 on trace gases emissions, in particular, of NO2 and CO2. In Europe, Italy was one of the first countries to be infected by the COVID-19 virus, starting in the beginning of February 2020, and numbers soaring up to over 100,000 infections and 20,000 deaths by mid-April. …
