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 …
Sea ice in key Arctic coastal regions is thinning at a rate of 70–100% faster than previously thought. These values, reported in a paper recently published in The Cryosphere, are derived when the sea ice thickness in the period 2002–2018 is calculated using new snow data with more realistic variability and trends. Results are outcomes …
An internal research fellow opportunity is currently open for applicants who have recently completed, or are close to completing a PhD in physics, engineering or Earth system science with research experience and peer-reviewed publications in topics relevant to the following fields: Polar and cryosphere science Ocean science Hydrology and water cycle Terrestrial carbon cycle Climate …
Between 2010 and 2019, the Gulf of Alaska lost 76 Gt of ice per year while High Mountain Asia lost 28 Gt of ice per year. These losses are equivalent to adding 0.21 mm and 0.05 mm to sea level rise per year, respectively. The results, based on interferometric swath processing of CryoSat-2 altimeter data, …
We are all familiar with the bolts of lightning that accompany heavy storms. While these flashes originate in storm clouds and strike downwards, a much more elusive type forms higher up in the atmosphere and shoots up towards space. So, what are the chances of somebody taking photographs of these rarely seen, brief ‘transient luminous …
A paper published recently in Earth System Science Data describes how scientists working in the OceanSODA project used measurements from ships and from satellites to show how ocean waters have become more acidic over the last three decades. Read the full story.
Gross primary production (GPP), the total carbon fixation by terrestrial ecosystems through vegetation photosynthesis, is being affected by drought and heat events. Previous studies have demonstrated how the duration and the intensity, as well as the timing of such events are controlling the GPP. A research conducted within the framework of the Earth System Data …
A recent paper investigates the role of Sea Surface Salinity (SSS) and Sea Surface Temperature (SST), together with Sea Level Anomaly and Argo profiles in Tropical Instability Waves (TIWs) in the equatorial Atlantic Ocean during the period 2010–2018. Tropical Instability Waves (TIWs) are a phenomenon in which the interface between areas of warm and cold …
A seminal article on the progress of satellite altimetry and its future has been published on-line in Advances in Space Research on 23 March 2021. It is authored by the International Altimetry Team, which is composed of more than 360 co-authors. In 2018, in Ponta Delgada, the Azores, Portugal, celebrations took place for 25 years …
For well over a decade, ESA’s SMOS satellite has been delivering a wealth of data to map moisture in soil and salt in the surface waters of the oceans for a better understanding of the processes driving the water cycle. While addressing key scientific questions, this exceptional Earth Explorer has repeatedly surpassed expectations by returning …
