AEOLUS+ INNOVATION – STUDIES ON WIND AND AEROSOL INFORMATION FROM LIDAR SURFACE RETURNS (SWAILS+)

Prime company: KNMI (NL)

In the SWAILS+ project the Aeolus lidar surface returns are used in combination with collocated wind speed observations to retrieve the aerosol optical depth. The retrieval algorithm under development, LARISSA (Lidar Aerosol Retrieval based on Information from Surface Signal of Aeolus), will complement the standard Aeolus (L2) aerosol profile products. Not only as LARISSA provides …

Harmonizing and advancing retrieval approaches for present and future polarimetric space-borne atmospheric missions (HARPOL)

Prime company: Netherlands Institute for Space Research (NWO-I) (NL)

Atmospheric aerosol particles strongly influence climate by scattering and absorbing light (direct forcing) and by changing cloud properties (indirect forcing). The corresponding radiative forcing represents one of the most uncertain radiative forcing terms as reported by the Intergovernmental Panel on Climate Change (IPCC). To improve our understanding of the effect of aerosols on climate and …

AEOLUS+ INNOVATION – IMPROVING DUST MONITORING AND FORECASTING THROUGH AEOLUS WIND DATA ASSIMILATION (NEWTON)

Prime company: NATIONAL OBSERVATORY OF ATHENS (GR)

Windblown dust plays a key role in the Earth system, affecting climate, marine and terrestrial ecosystems, anthropogenic activities as well as humans’ health. Winds, acting as the main driving force of dust emission determine also the spatiotemporal evolution of dust plumes during transport. The proposed study, entitled NEWTON, aims to demonstrate the potential improvement of …

CLIMATE DATA RECORD OF STRATOSPHERIC AEROSOLS (CREST)

Prime company: FINNISH METEOROLOGICAL INSTITUTE (FI)

Stratospheric aerosols impact the radiative forcing and thus the energy balance of the Earth’s atmosphere, therefore information about their distribution and variability is of high importance for climate related studies.  The main scientific objective of the project CREST is creating a new merged long-term time series of the vertically resolved aerosol extinction coefficients using data …

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. …
