Title: EXtending the Performance of AerGom to explore New aerosol related Species and to Improve OzoNe retrieval “EXPANSION”
Aerosols and ozone are particularly closely related climate variables. From a retrieval point of view, both affect significantly the extinction of the measured signal in the UV-Vis spectral region, making their distinction difficult in some cases. More fundamental is their link through atmospheric interactions, aerosols playing a crucial role in ozone physico-chemistry and ozone depletion. The algorithm used to produce stratospheric aerosol records in Aerosol_CCI is AerGom, a GOMOS retrieval algorithm optimized for stratospheric aerosols, based on lessons learned from the operational GOPR algorithm. The main output provided by AerGom is aerosol extinction provided over a large spectral range. Ozone is provided as a by-product, together with other ozone depleting gases such as NO2 and NO3. The EXPANSION project will explore, as its primary objective, the possibilities and performances of AerGom in the observation of ozone and ozone depleting trace gases. The aim is to obtain good quality vertical trace gas profiles, while keeping or improving the quality of aerosol extinction data. Cross-ECV consistency between stratospheric ozone and aerosol vertical profiles will be assessed using Ozone_CCI time series. Extending the use of AerGom toward Ozone_CCI scope is also expected to bring about a welcome feedback for further algorithm development in Aerosol_CCI.

Title: MIneral DUst SOurces using vertical profile information retrieved from IASI radiances “MIDUSO”
Airborne mineral dust is a climate active aerosol, with high global burden and an anthropogenic component linked to the land use. The objective of the project is to study mineral dust sources, using for the first time mineral dust daily (morning and evening) almost global 3D atmospheric distribution using data from IASI, the dust profiles being a side product of dust aerosol optical depth generated by Aerosol_cci. This datatset will be used to study Saharan and Asian mineral dust sources: geographic distribution, separation of source, pure transport and deposition areas, long term changes, partial quantification of the emissions, contribution to the diurnal cycle knowledge. To help interpret and to complete the information obtained from this new dataset, we will use land cover information and vegetation index seasonality data (obtained from the land cover CCI project).

Title: STatistics of AeRosol and CLouds INTeractions from satellite “STARCLINT”
The goal of the STatistics of AeRosol and CLouds INTeractions from satellite (STARCLINT) project is to obtain a quantitative assessment of the interactions between suspended aerosol particles and clouds. The long-term observational record enables the assessment of robust statistical relationships between atmospheric particulate and clouds, despite the superimposed modulation of regional to continental and mesoscale meteorology. STARCLINT will make use of the data sets generated within the ESA Aerosol_cci and Cloud_cci activities and, with the addition of complementary datasets, will identify correlations between aerosol particles and cloud in specific regimes across the globe for a time window of 20+ years. The outcome of STARCLINT will be therefore useful not only to the CCI working groups by building a bridge between their respective communities, but also to the climate model user groups by making a step toward an improved knowledge of the hydrological cycle. The work will in addition examine ocean-aerosol, ocean-cloud interactions.

Title: CCI data for assessing SOil moisture controls on FIre Emissions “CCI4SOFIE”
The objective of CCI4SOFIE is to improve the understanding of the links between climate and fire and improve estimates of global biomass burning emissions. The ESA CCI datasets of soil moisture, fire, land cover, greenhouse gases and aerosols, ESA DUE GlobEmission, and ESA STSE BIOMASAR biomass data in combination with European and non-European EO datasets of carbon pools and vegetation activity (NDVI, FAPAR) will be used to 1) empirically identify spatial-temporal patterns of soil moisture-vegetation-fire interactions, 2) to constrain and optimize a state-of-the-art dynamic global vegetation-fire model, and to 3) make projections of future soil moisture-vegetation-fire interactions and fire emissions.

Title: CARBOn dioxide emissions from FIRES (CARBOFIRES)
The focus of the CARBOFIRES project is the analysis of satellite XCO2 data products to estimate fire CO2 emissions for identified fire events. This involves identifying large fire regions that are consistent with XCO2 variation in time and developing associations between XCO2 observations and fire events and given those to conduct atmospheric inversion methods to determine fire CO2 emissions.

Title: The Environmental Response to Aerosols observed in CCI ECVs (ERACE)
This project aims to quantify the impact of aerosol on the radiation budget by post-processing the outputs of the aerosol and cloud_cci projects. Aerosols interact with radiation both directly by reflecting light and indirectly by altering the properties of clouds.

Title: Does Increasing Temperature Increase Carbonaceous Aerosol Direct Radiative Effect over Boreal Forests? (ITICA)
Aerosol particles are an important regulator of the Earth’s climate. One of the key quantities needed for accurate estimates of anthropogenic radiative forcing is an accurate estimate of radiative effects from natural unperturbed aerosol. The dominant source of natural aerosols over forested regions are biogenic volatile organic compounds (BVOC). In accordance with the expected positive temperature dependence of BVOC emissions, several previous studies have shown that some aerosol properties, such as mass and ability to act as CCN, also correlate positively with temperature at many forested sites. The goal of ITICA is to investigate whether a temperature effect on AOD occurs over the remote boreal forest region (about 50° N to 70° N), with a focus on Eurasia; and if it occurs, to quantify the influence of rising temperatures on the direct radiative effect of aerosols over the boreal forest.

Title: Ocean Colour at low sun and high waves (LowSun-OC)
Reflectance and transmittance properties of the sea surface depend on prevailing wind and wave conditions. Up to now, studies focused on sea surface roughness using the Cox and Munk model, which is based on wind speed-depending wave slope statistics. Wind also affects the underwater light field and resulting water-leaving radiance, and hence ocean colour estimates, particularly at low solar angles and in high latitude. This work aims at a revision of reflectance and transmittance properties of the wind-blown sea surface to account for wave effects on ocean colour estimates. The emphasis of this work is on influences of wave height and sea state on interactions of light with the air-sea interface and consequently to reduce uncertainties related to large zenith angles and high wind speeds in order to extend the usability of satellite data.

Title: Verification of high-resolution climate forecasts on Intera-seasonal-to-interannual Timescales with Advanced Satellite datasets of the Climate Change Initiative (VERITAS CCI)
VERITAS_CCI explores the verification of seasonal prediction hindcasts with the newly developed remote sensed observations of the ESA Climate Change Initiative (CCI) and places a special focus on the consideration of observational quality. The seasonal prediction hindcasts evaluate different prospects to improve seasonal forecast skill such as increased horizontal resolution or initialisation of the land surface and sea ice. The CCI observations of sea surface temperature, sea ice and soil moisture are used to judge whether these experiments lead to increased prediction skill but also to evaluate how well the observations agree with the models in order to inform about observational quality and likewise model quality.

Title: Surface water and climate variability from a high-resolution GIEMS-SAR merged product (GIEMS-SAR)
Changes in global surface water extent are closely related to changes in the global carbon cycle (CO2 and methane emission). However, the knowledge of the global distribution and dynamics of surface water remains limited. A Global Inundation Extent from Multi-Satellite (GIEMS) dataset of monthly inundation and surface water dynamics at about 25 x 25 km2 resolution has been produced by a multi-sensor analysis covering 1993-2007. In spite of the high value of this dataset for hydrology and climate studies, its low-resolution limits the observations to only 20% of the global inland surface water. The objetcive of this project is to examine if it would be possible to develop a SAR-based downscaling methodology to derive high-resolution surface water extent from the existing GIEMS low-resolution dataset.

Title: CryoSat measurement of the Antartic Ice Shelf thickness change (CryoShelf)
Floating ice shelves that fringe the majority of Antarctica's coastline provide a direct link between the ice sheet and the surrounding oceans, and changes in their constitution have been shown to influence the flow of inland ice due to their buttressing effect. This process has become increasingly important over recent decades as Antarctic ice shelves have thinned, retreated, and collapsed. Fluctuations in the surface elevation of the grounded ice sheet over time are developed as an essential climate variable within the ESA Climate Change Initiative and data users prioritised this parameter among the top three of all Earth Observation data sets. This project outlines has the objective to adapt and use the repeat track processor developed as part of the Antarctic and Greenland CCI projects to measure ice shelf thickness change and basal melt rates in Antarctica.

Title: Climate Impact on Marine Ecosystem State (CLIMARECOS)
The ocean plays a major role in the climate system, absorbing, between 1971 and 2010, approximately 30% of the carbon dioxide (CO2) emitted to the atmosphere by human activities. This CO2 sink is part of a very active, natural carbon cycle, through which phytoplankton in the surface layer of the ocean fix CO2 into organic matter, some of which subsequently sinks below the mixed layer. Through this process, phytoplankton help to modulate the increase in atmospheric CO2 that results from the burning of fossil fuels. Thus, phytoplankton are key players in the planetary carbon cycle, and it is therefore important to understand phytoplankton dynamics, which in turn depend on the underlying physical forcing (light, temperature, and winds). This project examines the influence of climate variability (as indicated by El Niño Southern Oscillation ENSO) and what can be learnt about potential impact of climate change on the marine ecosystem by studying its response to ENSO.

Title: ExpLoring thE Global cArbon CyclE through atmospheric GreenHouse Gas variability’(ELEGANCE-GHG)
This project focuses on assessing the year to year variations in the regional carbon exchange caused by both climatic drivers (e.g. temperature and precipitation) and disturbances (such as biomass burning, deforestation or a major El Nino event). This will be achieved by examining temporal and spatial anomalies in satellite-derived atmospheric CO2 and CH4 measurements and linking such anomalies to temporal variations in plant phenology, wetland extent, land-use change and fire activity along with the associated physical drivers such as land surface temperature (LST) and precipitation.
