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 …

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 …

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. …

Impact study of COVID-19 lockdown measures on air quality and climate (ICOVAC)

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

The global crisis due to the pandemic spread of the coronavirus COVID-19 that the humanity is facing since early 2020 led to unprecedented measures taken by different governments worldwide in order to limit as much as possible the number of impacted persons. Those measures include social distancing, banning of people gathering and travels, encouragement for …

CITYSATAIR

Prime company: KNMI (NL)

More than half of the world’s population is living in cities. According to the WHO air quality database 80% of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed WHO limits. Narrowing down to cities in low and middle income countries with more than 100 000 inhabitants, …
