Since the beginning of the industrial revolution humans have released approximately 500 billion metric tons of carbon into the atmosphere from burning fossil fuels, cement production and land-use changes. About 30% of this carbon dioxide (CO2) has been taken up by the oceans, largely by the dissolution of this CO2 into seawater and subsequent reactions …
The project aims at developing a new methodology for detecting anthropogenic carbon dioxide emission sources. CO2 data from OCO-2 and NO2, SO2 and CO data from Sentinel-5P are collocated. The plan is to analyze these data in synergy to better detect anthropogenic CO2 sources and plumes. In detail OCO-2 XCO2 data is deseasonalized and detrended, …
The project will investigate Northern Hemisphere methane (CH4) sources and their connection to the soil freezing and thawing at high latitudes. We will innovatively combine methods for monitoring of CH4 (methane) emissions in the Northern Hemisphere by applying both data from Earth Observing (EO) satellites and global atmospheric methane inversion model estimates. The EO data …
Living Planet Fellowship research project carried out by Diane Knappett. Global distributions of the methane (CH4) column average and carbon monoxide (CO) total column are observable by satellite shortwave infrared (SWIR) spectrometers through detection of surface-reflected solar radiation. Observations by ENVISAT SCIAMACHY and GOSAT-TANSO have been exploited extensively to investigate biogenic, pyrogenic and anthropogenic sources …
Living Planet Fellowship research project carried out by Marco Bellacicco. Phytoplankton is considered to be responsible for approximately 50% of the planetary primary production and is at the basis of the trophic chain. Large scale factors such as climate, ocean circulation, and mostly anthropogenic activities, affect phytoplankton biomass and distribution. For all of these reasons, …
Living Planet Fellowship research project carried out by Mariette Vreugdenhil. Through its role in the global water-, carbon- and energy cycles, vegetation is a key control in land surface processes and land-atmosphere interactions. Vegetation is strongly affected by variability in climate drivers like temperature, radiation and water availability. Vegetation phenology, the timing of vegetation phases, …
Living Planet Fellowship research project carried out by Jasdeep Singh Anand. Terrestrial ecosystems are a major carbon pool, and so act to mitigate anthropogenic climate change. However, vegetation in these carbon pools are damaged by tropospheric O3, which is formed from anthropogenic NOx and aerosol emissions. Damaged vegetation cannot sequester as much carbon, so this …
Living Planet Fellowship research project carried out by Marco Celesti. The future FLEX/Sentinel-3 tandem mission will provide unique information on vegetation dynamics by exploiting Sun-induced fluorescence and reflectance at the unprecedented spatial scale of 300m x 300m. This magnified view into the photosynthetic machinery will enhance our ability to face the actual and future challenges …
Royal Research Ship James Clark Ross started its roughly 4000 miles, 40 days voyage across the Atlantic Ocean at the end of September. It has been carrying out in situ measurements with an array of instruments including above-water radiometric optical sensors that measure upwelling radiance from the sea surface for validation of satellite ocean colour, …
