Trans-National Access

The 5th H2020 ATMO-ACCESS call ( for "free-of-charge" TNA (Trans-National Access) is now open until September 25th 2023! .

Do not hesitate to contact the ATMO-ACCESS TNA team at the CMN-PV facility ( for any possible questions or further assistance.

A key goal of the ATMO-ACCESS project is to explore and test modalities of access to eventually identify an optimum sustainable access model. Whilst not essential, in the spirit of ATMO-ACCESS, and in preparation for future calls, innovative modes of access are particularly encouraged. Examples of such novel access proposals could include, but are not limited to:

  • combinations of remote and physical access

  • combinations of training and scientific delivery - innovation

  • cross-disciplinary access from beyond atmospheric science

  • simultaneous or sequential access to multiple facilities

  • simultaneous access by users from multiple sectors

  • piloting of use of facilities for novel purposes

  • ATMO platforms offering access for the first time

Potential interested users will be requested to write a short scientific project to be submitted to ATMO-ACCESS for an internal review (see more details at: For general questions and assistance related to TNA within ATMO-ACCESS,  contact the ATMO-ACCESS TNA team at

If you are interested to propose a field experiment (physical or remote) at the Mt. Cimone - Po Valley facility and you want to discuss particulars of access and practicalities before submitting the official TNA application, please contact us ( Examples of broad scientific topics (but not limited to) to be proposed can be related to:

  • atmospheric aerosols
  • reactive gases
  • non-CO2 greenhouse gases
  • fog and clouds

Accesses to the CMN-PV facility can be physical or remote. By physical access, foreign research teams physically access the Po-Valley facility (or a single component of the facility) for performing the proposed experiment. By a remote access, foreign research teams can remotely access the instrumentations they installed at the Po-Valley facility (or at a single component of the facility) as well as the datasets produced by the CNR-ISAC instrumentation. The possibility also exists that foreign research teams ship their instrumentations to the facility and ISAC-CNR takes care of the installation.

Incoming proposals will be checked for formal compliance with the EU regulations, logistical and technical feasibility and scientific relevance. TNA providers also evaluate the feasibility of contributing in part to users' travel and subsistence (T&S) expenses, based on the users' cost estimates and the available budget allocated specifically for this. The opportunity/feasibility of supporting part of the user's T&S costs and the amount of the contribution will be decided on a case-by-case basis In view of the visit and during the access, users can count on:

  • on-site assistance by the TNA provider, which includes the logistical, technological and scientific support and the specific training usually provided to external researchers using the infrastructure/installation (see more on;
  • limited financial support for travel and subsistence, which is available to some extent upon request to the TNA provider. The amount and conditions of the financial contribution will be established by mutual agreement between the user and the TNA provider at the moment of arranging the visit. The TNA provider manages the refund according to its internal rules
