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 …
Stratospheric aerosols play an important role in the Earth system and in the climate. Through the scattering of solar radiation back to space and by heating the stratosphere through the absorption of thermal infrared radiation upwelling from the troposphere, stratospheric aerosols impact the radiative forcing and thus the energy balance of the Earth’s atmosphere. By …
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. …
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 …
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, …
The main part of the project is to develop a total ozone product for Ocean and Land Colour Instrument (OLCI) on board Sentinel 3 A,B. The product will be derived using the Sentinel-3A, B OLCI Level 1 Full Resolution data. The cloud mask, snow mask, and atmospheric correction procedures will be also developed. OLCI measurements …
The ESA Methane+ project aims at exploiting the SWIR and TIR CH4 observations from different satellites in order to better differentiate between sources and sinks of CH4 on the regional and global scale. For this we will use the CH4 observations of TROPOMI on Copernicus Sentinel-5p, IASI on MetOp-B, and CrIS on Suomi NPP in combination with atmospheric inversion models. OBJECTIVES: Given the identified opportunities and challenges of …
