What's New?: 

ARISTO-2016 took place in July - August 2016.

The proposal submission was through February 19, 2016 and is now closed.

ARISTO is an annual NCAR / NSF test flight program. Look for the next year's ARISTO on the EOL web site.

Project Description: 

What is ARISTO?

The Airborne Research Instrumentation Testing Opportunity (ARISTO) is a newly-created NSF-sponsored flight test program that will be conducted annually on one of the NSF/NCAR aircraft. The purpose of the ARISTO program is to provide regular flight test opportunities for newly developed or highly modified instruments as part of their development effort. The program was created in response to a critical need, expressed by the NSF community, for regularly scheduled flight-testing programs to be able to not only test instrumentation, but also data systems, inlets and software well ahead of a field campaign in order to maintain cutting-edge and vibrant airborne research.  Click here to view the original ARISTO proposal.

The ARISTO 2016 flight test program will take place in summer 2016 at EOL's Research Aviation Facility (RAF) located at Rocky Mountain Metropolitan Airport (RMMA) in Broomfield, CO.  Information on eligibility, proposal submission, timelines, and instrument requirements can be found on this page.    


Who is eligible to participate in ARISTO?

All instrument developers/investigators with existing NSF funds related to instrumentation are eligible to apply for access to the NSF/NCAR aircraft for this instrumentation testing. Investigators selected for instrument testing are required to provide appropriate details on their instrument and comply with EOL/RAF certification requirements.

Please note that this flight-testing program is not intended to provide flight opportunities for commercial instrument builders or for the collection of proprietary data for commercial instrument development. Test flight opportunities can be opened to investigators with instrument developments funded by non-NSF U.S. agencies, however those arrangements will have to be negotiated between the cognizant Program Officers.

Proposals will be ranked and instruments will be selected for testing based on the following prioritized criteria:

  • Priority 1: Instrumentation that is essential to an NSF-funded or proposed field campaign but that has yet to be test flown and certified on an NSF/NCAR aircraft.  
  • Priority 2: Instrumentation that has recently been developed or is being modified as part of a funded NSF grant or cooperative agreement.
  • Priority 3: Instrumentation that has a high likelihood of being routinely used by the NSF community in future field campaigns.
  • Priority 4: Instrumentation that has a high likelihood of being ready for flight-testing and complies with all EOL/RAF certification guidelines.
  • Priority 5: Instrumentation that is of high relevance to unfulfilled needs in the Lower Atmospheric Observing Facilities (LAOF) and/or in the U.S. airborne research fleet.
