e-shape pilot 2.3 organized, on the 1^st of April, a successful dedicated webinar to the Health Surveillance Air Quality [HSAQ] pilot with the main goal to showcase success stories and results to the general audience.

More specifically, the main objectives of the event were:

• To introduce the newly developed TEASER online platform: a *marketplace of services* with global and unique city components utilizing a variety of existing EO infrastructure for health surveillance purposes.
• To interact with existing stakeholders towards the optimization of the TEASER
• To attract new stakeholders
• To introduce the e-shape Help Desk: a key tool for linking users with the pilot teams and to insure efficient and fruitful exchanges between “clients and service providers”

More than 50 participants attended the webinar, from almost 20 Organizations mainly from the public sector, and including ‘new stakeholders’ i.e. Organizations not having participated during the co-design process, or not already exchanged information with the pilot partners.

Indicatively: Region of Attica (Gr), ARPA Puglia Taranto (It), Hellenic Statistical Service (Gr), Ministry of Health (Gr), National Public Health Organization (Gr), Municipality of Bari (It), Clear Air Task Force (Gr), Dipartimento di Epidemiologia del Servizio Sanitario Regionale (It), Center for International Climate Research (No), Norwegian Institute for Public Health (No), European Commission (EU).

After the short presentations and the introduction to the newly developed Teaser platform, an interaction with the participants took place, mainly through the chat channel. Lastly, a short introduction and guide focusing in the e-shape Help Desk was performed, so that stakeholders stay connected, providing comments or questions for the HSAQ pilot.

During this webinar, the results of activities in all pilot cities (Helsinki, Athens, Munich, Bari, world megacities from UNESCO list) on the health-related air pollution outputs (e.g. population exposure to air pollution, SDG11.6.2, Aggregated Risk Index) were demonstrated. Afterwards, the teaser platform was presented and explored, which is the marketplace of all services provided to end-users. The teaser platform can re-direct stakeholders to the individual platforms for each pilot city (e.g. https://www.alpendac.eu/eshape, https://sampo.fmi.fi/airpollution/no2/, https://www.nextgeoss-airquality.de/).

The EU project officer provided positive feedback on the organization and the content of the webinar. The discussion that followed was mainly directed to the possibility of including more pollutants to the analysis (e.g. nanomaterials or methane) and to particularities in the fusion processes of data from different EO platforms (e.g. in situ measurements and satellite products).

Beyond the already established collaboration (in the frame of HSAQ) with several stakeholders, the Public Health Organization of Greece has offline provided positive feedback for the webinar, and is expecting further physical meetings to evolve the pre-engagement during the co-design process.

Fast facts:

Pilot 2.3 (PI Evangelos Gerasopoulos, NOA), is the Health Surveillance Air Quality Pilot (HSAQ), focused on EO-based pollution-health risks profiling in the urban environment. The objectives of this pilot are:

• To improve AQ-health information, from air pollution data and land use/health/socio-economic features of cities, for use in public health assessment and urban planning.
• To evaluate and exploit citizen science data towards their integration with the official measurements.
• To strengthen decision making by allowing for pollution mitigation scenarios and provision of alerts.
• To raise awareness on AQ implications on public health, enhancing the citizen participation.
