ACTRIS-2 Collaboration with EUFAR


EUFAR is an EU FP7-Integrating Activity (2014-2018) with the aim to provide researchers with easy and open access to the airborne research facilities that are most suited to their needs. EUFAR works to coordinate the operation of instrumented aircraft and remote sensing instruments. The high maneuverability of instrumented aircraft allows researchers to pursue atmospheric phenomena, especially useful in remote locations, follow their evolution and explore their chemistry and physics from small spatial sales up to thousands of kilometers. Within EUFAR, TransNational Access is offered to 17 instrumented aircraft ranging from a low- and slow-flying small single-engine aircraft (ENDURO) to a 4-engine jet aircraft that is capable of carrying several tons of instrumentation payload (BAe146).


ACTRIS-2 supports collaborations with other environmental research infrastructures. ACTRIS-2 users interested in projects that require the use of instrumented aircraft are encouraged to collaborate with EUFAR to benefit from joint access to both facilities. Although collaborative ACTRIS-2/EUFAR TNA activities will require separate applications to each TNA programme in order to be compliant with their respective procedures, concerted ACTRIS-2/EUFAR TNA projects will be strongly supported. Collaborative TNA actions can be envisaged through:

·        parallel (joint) applications to both ACTRIS-2 and EUFAR, specifying the need of the respective facilities in each proposal form,

·        complementary applications to either TNA programme (e.g., in case an ACTRIS-2 proposal is already accepted),

·        joining an existing research group developing a current EUFAR2 TNA project.

Interested users should ensure to clearly specify the requirements and needed support from each facility in the proposal form. The evaluation of collaborative activities will be coordinated by the TNA managers of both ACTRIS-2 / EUFAR projects.

Progress 2017: So far EUFAR partnership with ACTRIS advances as access opportunities are provided to European researchers from over 30 Institutes to study in detail the aerosol composition and dynamics over Eastern Mediterranean. The core ACTRIS/EUFAR activity is concentrated over Crete with the PRE-TECT experiment (1-30 of April), aiming on desert dust microphysical characterization from remote sensing, employing advanced inversion techniques developed in the framework of ACTRIS, focusing on aerosol absorption to fulfill the objectives of the ACTRIS JRA1 activity (“Improving the accuracy of aerosol light absorption determinations”). Two TNs have been awarded by EUFAR, providing in total of 16 aircraft flight hours with DLR Falcon to evaluate the ACTRIS ground-based retrievals. A number of atmospheric experiments will be implemented during the same period in Eastern Mediterranean, utilizing their own data and synergies with ACTRIS/EUFAR datasets in order to fulfil their objectives. In short, two ERC projects will have their first experiments over Eastern Mediterranean (A-LIFE: and D-TECT:, the GEO-CRADLE project ( will evaluate two of its thematic pilots in the area (dust forecasting and energy services) and the Copernicus CAMS Atmospheric Service will be evaluated against ACTRIS and EUFAR in-situ products from students that will run exercises in the framework of their participation in the summer school that is organized for ECARS-TWINNING project ( Moreover, an advanced Cloudnet training school is organized by TROPOS in Cyprus during the same period (
