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: UNIVERSITAET 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 …

WORLD EMISSION

Prime company: GMV AEROSPACE AND DEFENCE, SA (ES)

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 …

High information content ozone profile algorithm for ground-based passive remote sensing instruments (OPA)

Prime company: LUFTBLICK OG (AT)

LuftBlick Earth Observation Technologies (LuftBlick) and the Royal Belgian Institute for Space Aeronomy (BIRA) propose to develop a novel algorithm to derive ozone profiles from measurements of ground-based passive remote sensing instruments. These are the highlights of our proposed activity: The novel algorithm distinguishes itself in several ways from existing approaches: It uses MAX-DOAS sky …

3rd EUMETSAT/ESA/ECMWF joint training in atmospheric composition

December 6, 2021 - December 17, 2021

The European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Center for Medium-Range Weather Forecasts (ECMWF) with the Copernicus Atmosphere Monitoring Service (CAMS) organised the third joint training course on Atmospheric Composition from 6 to 17 December 2021. The training presented the state-of-the-art in atmospheric monitoring and modelling. …
