ARSINOE - Climate Resilient-Regions through Systemic Solutions and Innonations

Funding: European Commission / European Climate, Infrastructure and Environment Executive Agency (CINEA)

Description: ARSINOE develops the methodological framework for the combination of System Innovation Approach (SIA) with the Climate Innovation Window (CIW) to create an ecosystem for climate change adaptation solutions. ARSINOE creates this ecosystem with a three-tier, approach: (a) using SIA it integrates multi-faceted technological, digital, business, governance and environmental aspects with social innovation for the development of adaptation pathways to climate change, to meet EU Green Deal targets for specific regions; (b) it links with CIW to form innovation packages by matching innovators with end-users/regions via for specific regions; (c) it fosters the ecosystem sustainability and growth with cross-fertilization and replication across scales, at European level and beyond, using specific business models, exploitation and outreach actions. The ARSINOE three-tier approach is show-cased in nine widely varied regions across Europe (demonstrators), as a proof-of-concept with regards to its applicability, replicability, potential and efficacy.

Role of APCG: APCG will participate in the Greening of Athens Metropolitan Area (AMA). Mapping urban biodiversity elements in Athens will enable the identification of hotspots of Urban Green Spaces (UGSs). In order to evaluate the functionality of UGSs in AMA, two parameters are going to be investigated: i) accessibility: the concept of the 15-minute city will be utilized to ensure that all citizens meet their needs in terms of having access to parks and open-green spaces on foot or by bike, within 15 minutes, highlighting the comparative advantages with respect to traditional urban mobility means (i.e., cars, buses). This is aligned with ensuring social inclusion and connectivity of neighborhoods, while at the same time improving urban biodiversity by addressing ecosystems’ fragmentation and ii) biodiversity conservation: the assessment of the connectivity of protected areas in AMA will pave the ground for a coherent nature network, fully complying with the EU Biodiversity Strategy for 2030. The assessment will also use Earth Observation derived urban metrics. Overall, according to UGSs functionality assessment, the effectiveness of existing Nature Based Solutions (NBSs) will be evaluated and new NBSs will be proposed, where needed. The identification of UGS hot spots will form the City Green Infrastructure as a dynamic tool to be included into city strategy to put urban biodiversity into practice, and to quantify scenario-based health co-benefits related to Αir Quality (AQ) (city scale AQ modelling at 100x100 m2).

DOMOS - Dust-Ocean Modelling & Observing Study

Funding: European Space Agency

Description: The Dust-Ocean Modelling & Observing Study (DOMOS) will advance the understanding of dust and ocean interactions in a changing climate through an innovative use of model and observations. The project will develop a new retrieval of dust deposition from satellite lidar data (CALIPSO and Aeolus), will validate the dust deposition field from the CAMS reanalysis and will also provide assimilation tests of IASI and Aeolus aerosol products with the goal of providing a better description of the dust aerosols, for applications in aerosol radiative impacts and ocean biogeochemistry. An improved representation of the physical and chemical characteristics of dust deposition over the ocean is crucial to interpret the observed climatic change responses and to better describe the future ones. This includes a better understanding and quantification of the deposition of soluble iron from natural and anthropogenic dust and of its contribution relative to biomass burning and anthropogenic aerosols which will be one of the main deliverables of the project. A scientific roadmap to highlight the findings of the project and identify possible gaps in the modelling and the observing approaches will also be provided.

Role of APCG: Production of state-of-the-art soluble iron deposition datasets using an improved version of the state-of-the-art Earth System Model EC-Earth3 ((Myriokefalitakis et al., 2021). EC-Earth3 contains an advanced representation of the atmospheric iron cycle, which allows quantifying the contribution of different sources and processes to the soluble iron deposition into the ocean. Our simulations will overall cover a sufficiently long period in the present time (1990 to 2019) to create dust and iron deposition climatologies in a monthly frequency.

GAUSS - Generating Advanced Usage of Earth Observation for Smart Statistics

Funding: European Space Agency Express Procurement [Plus] – [EXPRO+]

Description: The overarching objective of this project is to develop and demonstrate applications that advance the use of Earth Observation (EO) data in the European Statistical System. Detailed discussions with the National Statistical Offices (NSOs) of Poland, Greece and Finland have taken place as to how this aim can best be achieved. The NSOs will closely follow the activities of the project as well as offer key insights throughout its duration. The consortium has strong links with each of these agencies. NOA has a memorandum of cooperation with ELSTAT for integrating Earth Observation in support of official statistics. IGIK has built a strong relationship with Statistics Poland through the EO4STAT project and others, while FMI and its local partner SYKE provide key data to Statistics Finland. Based on the discussions, a set of case studies of active and clear interest to the agencies have been identified for which the addition of EO data can significantly improve the quality of statistics with respect to current capabilities. These focus on the domains of air quality, well-being and water statistics, though they also have some applicability to other domains. These case studies should become the basis of new operational EO-based services provided to the NSOs, becoming showcases for how EO data can help the NSOs and opening the door to wider adoption of EO by the statistical community. They are chosen to be new and innovative from the perspective of the agencies, while also being sufficiently mature so as to provide a successful demonstration. The project, lessons learnt and barriers will be closely documented in a Roadmap which will delineate the process of EO becoming a solid part of the Trusted Smart Statistics concept, while also opening up new avenues for the broader use of EO by the National Statistical Offices.

Role of APCG: Project Coordination - Implementation of the Greek case study on air quality. Enhancement of the current practices of the Greek NSO regarding the Air Quality Directive (AQD) IPR Reports (statistical product 114 in the NSO’s work programme) by integrating satellite, smart-sensor and modeling data to the current data provided by the regulatory network, while spatially reaching a resolution of LAU level (as opposed to the current coarse disaggregation).

QA4EO - Quality Assurance for Earth Observasion

Funding: European Space Agency Service Agreement - QA4EO/SER/SUB/30 - "Quality Assurance framework for Earth Observation: QA4EO"

Description: Under the framework of QA4EO funded by European Space Agency (ESA), the project “AOD@440nm - Improved aerosol retrievals using NO2 correction” aims to improve the retrievals of Aerosol Optical Depth (AOD) of different ground based networks (AERONET, SKYNET, PGN) and of satellite algorithms (S5P/TROPOMI). Main motivation is the improvement of aerosol optical depth (AOD) and Ångström exponent (AE) datasets based on a correction using synchronous NO2 data. Development of this method is based on the fact that currently satellite climatological NO2 values are used for correcting the AOD retrievals for NO2 related optical depth. However, NO2 has high spatiotemporal variability and, hence, these values are rarely representative of the actual atmospheric conditions. Recently developed PGN offers reliable, high measurement frequency ground-based data for NO2 column, alongside with current generation of satellites (S5P/TROPOMI) which provide a high NO2 spatial detail. These data will be used to evaluate the current uncertainty of AOD and AE retrievals and integrated procedures will be developed. Spatiotemporal AOD/NO2 characteristics using two (urban and suburban) neighbouring ground based stations (including AERONET, PGN and EUROSKYRAD related instrumentation) and satellite sensors will be analysed towards demonstrating the NO2 impact on AOD for such validation activities and ways to correct for it.

Role of APCG: APCG members lead the WP2: “Improved surface based aerosol retrievals using NO2 correction”. This WP is constituted by the development of algorithms, the assessment of the products, the estimation of uncertainties and the appliance of QA procedures.

RI-URBANS responds to urgent needs to substantially reduce air pollution across EU by providing enhanced AQ observations in support of advanced AQ policy assessment. We develop and enhance synergies between AQ Monitoring Networks (AQMNs) and RIs in the atmospheric domain and combine advanced science knowledge and innovative technologies to develop pilot STs. These will enhance the AQMNs capacity to evaluate, predict and support policies for abating urban air pollution. RI-URBANS deploys tools and information systems in the hands of citizens and communities to support decision-making by AQ managers and regulators. The focus is on ambient nanoparticles and atmospheric particulate matter, their sizes, constituents, source contributions and gaseous precursors. RI-URBANS will evaluate novel AQ parameters, source contributions, and their associated health effects to demonstrate the European added value of implementing such STs. The project builds on existing initiatives for advanced research-driven AQ observations at supersites from European cities to provide the innovative AQ STs. Five implemented pilots in 9 cities will demonstrate the ability to integrate complementary STs in AQMNs and data management using FAIR (Findable, Accessible, Interoperable, Re-usable) principles. RI-URBANS will address all aspects of sustainability, including efficient curation, preservation and provision of access to data, training and capacity building, and how the use of tools will be secured in the future. Finally, upscaling and sustainability will be provided to the offered AQMNs-RIs interoperable services, using advanced instrumentation, modelling, source apportionment, integrated citizens observatories and mobile measurements.
