Request Process for Small Field Campaigns


The LAOF request process is determined on the basis of the complexity of the field component and the deployment costs.  In general, small field campaigns display one or more of the following attributes:

  • Domestic or "friendly" (as deemed by a review committee) foreign deployments
  • Small investigator team and few individual science proposals
  • Involvement of a single or small number of LAOF
  • Straight-forward deployment logistics
  • Little to no interagency collaboration
  • LAOF deployment costs under $1.25 Million

Since exceptions to these general guidelines will occur, it is essential that Principal Investigators discuss all proposed field activities with their NSF Program Officer as well as the appropriate Facility Managers in a timely manner.  If you are unsure how your project would be classified, please contact NSF or the LAOF Request Coordinator for guidance.


  • Letter of Interest (LoI)
  • Facility Request
  • Scientific Grant Proposal(s)
  • Project overview in the form of a presentation


For small field campaigns, NSF facilities can be requested twice annually. 

The lead investigator is responsible for taking the outlined actions and for providing the following material to NSF and the LAOF Partner Organizations. If you are unfamiliar with the mentioned documentation, please review the Request Documentation Definition section of this website.
FY-n references refer to the fiscal year (October through September) in which an action has to be taken. The campaign will take place in FY-0, FY-1 refers to one fiscal year ahead of the campaign, etc.
  • Anytime in FY-2: Initiate contact with your NSF Program Officer and the Facility Manager(s) of the appropriate LAOF Partner Organization to alert them of your intentions and get preliminary advice concerning timing and objectives. 
  • 1 March / 15 September FY-2: Submit a Letter of Interest to the NSF LAOF Program Director and LAOF Request Coordinator.
  • June / November Timeframe FY-2: Contact your NSF Program Manager well in advance to discuss and receive advice on the timing of submitting your science proposal to NSF. 
  • 1 July / 1 December FY-2Complete the Facility Request Form(s) and upload up to six science presentation slides via PRESTO
    • 1 July FY-2 for the use of a facility(s) between 1 October and 31 March of FY-0 and
    • 1 December FY-1 for the use of a facility between 1 April and 30 September in FY-0.
    • For example, requests for facility use between 1 October 2018 and 31 March 2020 will be due by 1 July 2022. Requests for the use of a facility between 1 April and 30 September 2020 will be due by 1 December 2022.
    • Please note that deadlines are strictly enforced.
  • 31 August / 31 January FY-2: Submit an electronic copy of the scientific project description of the relevant Scientific Grant Proposal(s) to

Your request will be discussed at either the Fall OFAP or Spring OFAP meeting in the year before your actual deployment phase.



The review of each project proposal is handled through the NSF merit review process. The final decision by NSF is usually reached within two to three months of the OFAP meeting. Your NSF Program Officer will contact you directly to inform you about her decision to recommend or decline the request.



Please note that NCAR-led small field campaigns are handled slightly differently due to the unique relationship between NSF/AGS and NCAR. Please follow the procedures described under "Review Procedures for NCAR-led Science Proposals."
