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 SUNLIT project aimed at developing new global tropospheric ozone datasets using combination of total ozone column from OMI and TROPOMI with stratospheric ozone column dataset from several available limb-viewing instruments (MLS, OSIRIS, MIPAS, SCIAMACHY, OMPS-LP, GOMOS). The novelty of the SUNLIT approach is using measurements from several satellite instruments in limb-viewing geometry for deriving …
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 …
A good aircraft heating was necessary to secure proper functioning of the on-board instrumentation during the airborne campaign that took place last November in the Arctic, flying between Ottawa and Iqaluit. The campaign exploited several radars and lidars to measure cloud particles and precipitation by looking at signals bouncing off ice crystals and water droplets …
In current atmospheric trace gas retrieval schemes exploiting UV-vis sounder data, clouds are treated in a simplistic way ignoring 3D structures and cloud shadows. In this activity, the impact of such cloud effects on trace gas products is quantified, building on statistical analyses of cloud observational data and on 3D Monte Carlo radiative transfer simulations …
This project estimates of the air-sea flux of CO2 calculated from a suite of satellite products over a range of Atlantic Ocean provinces. It deploys state-of-the-art eddy co-variance methods to provide independent verification of satellite estimates of CO2 gas exchange over the Atlantic Ocean. The project provides Fiducial Reference Measurements from the AMT28 (from 23rd …
The gravity gradients of the highly successful ESA Earth Explorer mission GOCE (Gravity field and steady-state ocean circulation explorer), which have been reprocessed by applying enhanced calibration strategies in the frame of the ESA project GOCE High-level Processing Facility (HPF), have reached a very high quality level, especially in the long-wavelength spectral range where the …
“The fellowship provided me the opportunity to develop the first TROPOMI HDO data product and the first such product including cloudy scenes.” After the end of the Living Planet Fellowship, Andreas was at the Finnish Meteorological Institute (FMI), working on the development of a a novel balloon-borne instrument for the measurement of HDO and …
Land ice mass loss is the largest source of global sea level rise. Since 1992, two thirds of sea level contribution from land ice comes from the Arctic. Roughly half of Greenland ice sheet mass loss is from increased surface melting. The fraction from surface melting is even higher for smaller Arctic ice masses. The …
Living Planet Fellowship research project carried out by Ivan Pakhotin. Ivan’s recent published work in magnetosphere-ionosphere coupling (MIC) using the unprecedented Swarm dataset has revealed that Alfven waves play a key role in MIC dynamics, with small scales carrying very significant amounts of energy. His recent preliminary work has further indicated that in fact most …
