Permafrost thaw: it’s complicated
A special collection of papers examining the physical, biogeochemical and ecosystem changes related to permafrost thaw and the associated impacts has been recently featured on the Nature Reviews Earth & Environment journal. One of the papers in the collection, describing how scientists from Europe and the US are working together to better track permafrost carbon …
Career opportunities for internal research fellow in Earth System science
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 publication records. The applicant may select his/her preferred theme between: Ocean science Activities will focus on exploiting the latest advances in EO satellite …
Satellites highlight a 30-year rise in ocean acidification
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.
Vegetation modulates the impact of climate extremes on gross primary production
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 NASA and ESA collaborative community initiative on Arctic methane and permafrost
The IPCC Special Report on the Ocean and Cryosphere in Changing Climate (2019) includes “permafrost carbon and greenhouse gas emissions” as one of the cases characterised by deep uncertainty. The report states that even if there is a very high confidence that “permafrost temperatures have increased to record high levels including the recent increase by …
20-year time-series of global primary production in the oceans
In a recent paper published in Remote Sensing, scientists used data from the Ocean Colour Climate Change Initiative to study the long-term patterns of primary production and its interannual variability. Combining long-term satellite data with in situ measurements, they assessed global annual primary productivity from 1998-2018. Being able to observe and quantify primary production over …
A collaboration on Carbon science
The carbon cycle is central to the Earth system, being inextricably coupled with climate, the water cycle, nutrient cycles and the production of biomass by photosynthesis on land and in the oceans. In the natural system the balance among carbon in the atmosphere, land and ocean is regulated through fluxes between these three main reservoirs. …
ESA and EC sign cooperation agreement on Earth system science
ESA and the European Commission’s Directorate General for Research and Innovation (DG-RTD) have signed an agreement to join forces to provide a coordinated response to the grand science challenges of the next decade. With this agreement ESA and DG-RTD aim at establishing an effective alignment of selected scientific activities under Horizon Europe and FutureEO programmes …
TOP: atmospheric multi-source data cube
Currently we speak of the ‘golden age’ of Earth Observation (EO). Not only can we access a variety of data from heritage and current EO missions serving scientific and operational needs, new systems for monitoring our blue planet are constantly being planned, built, and sent into the Earth orbit. Regarding atmospheric science, a major step …
