The support project ACTRISâŻIMP was funded by UEFISCDI under the âSupporting Participation in HorizonâŻ2020â call (PNâIIIâCEIâSUPORTâPOâ2020), and was launched to follow up an earlier HorizonâŻ2020 infrastructure grant (ACTRIS PPP). Its main goal was to help transition ACTRIS from a project-based network to a centralized panâEuropean research infrastructure, in full alignment with the European ACTRIS RI strategy.
The ACTRISâŻIMP project (Aerosol, Clouds and Trace Gases Research Infrastructure Implementation Project) was financed by the European Commission under HorizonâŻ2020 (GrantâŻ871115, H2020âINFRADEVâ2018â2020 /âŻ2019â2), and was scheduled for a four-year duration starting 1âŻJanuaryâŻ2020. It built on the achievements of ACTRISâŻPPP, and was designed to increase national partnerships and to support INOEâs Remote Sensing Department by consolidating international collaborations and disseminating ACTRISâŻIMP results at both national and international scientific events.
Execution Phase 1 (JanuaryâDecember 2021) aimed to expand and strengthen collaboration with national and international partners. Key activities included:
- Organizing an ACTRISâRO meeting on 1â2 September 2021 at the Magurele Centre for Atmospheric and Radiation Studies (MARS), hosted by INOE2000 and attended by UBB, UAIC, UGAL, INCAS, and INOESY SRL;
- Participating in remote and in-person working group meetings and seminars (e.g., ACTRIS European seminars, COSTârelated events) throughout 2021;
- Contributing to international scientific conferences in 2021, such as the European Aerosol Conference (EAC2021, 30 Augustâ3 September) and the European Lidar Conference (ELC2021, 16â18 November).
Execution Phase 2 (JanuaryâDecember 2022) focused on updating research infrastructure concepts and increasing INOEâs scientific visibility. This phase included:
- Two ACTRISâRO consortium meetings: 26â29 January 2022 in Cheile GrÄdiČtei, BraČov; and 8â9 September 2022 on the MÄneciu Experimental Platform in Prahova, hosted by INCAS, with participation from all national ACTRIS facilities;
- The INOE Remote Sensing Department taking part in 42 working meetings with international expertsâincluding ACTRIS EU seminars and COST projectsâheld both online and onsite;
- Attendance at 12 international scientific events, including Virtual JATAC Data Workshop; 1st ACTRIS Science Conference; âSpaČiu Či Securitate pentru Europa de Estâ exhibition; 2022 Living Planet Symposium; Scientific Research and Education in the Air Force (AFASES 2022).
Execution Phase 3 (JanuaryâDecember 2023) aimed to further consolidate INOEâs capacity within the ACTRIS infrastructure. Activities included:
- An online ACTRISâRO meeting held on 8 June 2023 via Webex, organized by INOE 2000, with participation from RADO Bucharest (INOE), RADO Cluj (UBB), RADOâGalaČi (UGAL), RADOâIaČi (UAIC), and ATMOSLAB (INCAS). Presentations covered the first General Assembly of ACTRIS ERIC (5â6 June 2023, Helsinki), including governance, data policy, access regulations, recruitment, and procurement;
- Numerous working meetings with international experts throughout 2023âcovering ACTRIS ERIC General Council meetings, CARS ARES webinars, and COST programmes HARMONIA CA21119 and PROBE CA 18235âheld both online and onsite;
- Participation in major international conferences in 2023, such as RSCy2023, EGU2023, ECSS2023, Aeolus Science Conference 2023, 3rd Lidar International Workshop, and EAC2023.
The project ran between 2020 and 2023.
