Amendment 16: A.17 ARCSIX Change to Field Campaign Schedule and Budget.

The Radiation Sciences and Cryosphere Programs are jointly soliciting proposals for participation in an airborne campaign to be conducted in the Arctic. The Arctic Radiation-Cloud-Aerosol-Surface-Interaction Experiment (ARCSIX) is an airborne investigation from Northern Greenland and possibly Svalbard.

ARCSIX is driven by the need to:

  1. Understand how coupling between radiative processes and sea ice surface properties influence summer sea ice melt;
  2. Understand processes controlling the predominant Arctic cloud regimes and their properties; and
  3. Improve our ability to monitor Arctic cloud, radiation, and sea ice processes from space.


ROSES-2021 Amendment 16 amends A.17 ARCSIX to change the Schedule for the Field Campaign and hence the Budget. The ARCSIX field campaign will be deferred to May through mid-July, 2024. Consequently:

  1. The number of years of funding will be one year longer: Instrument proposals may request funding for up to six years and flight planning proposals may request funding for up to four years
  2. Funding in the first project year should cover the cost of a virtual science team meeting and, for flight planning proposals, support for a modest amount of preparation and practice flight planning
  3. Funding in the second project year should cover the cost of preparing for the field campaign and an in-person science team meeting
  4. Funding in the third project year should cover the costs associated with the field campaign
  5. Funding in post-campaign project years should be as originally specified in this ROSES element.


The due date for proposals remains unchanged: Notices of Intent to propose are not requested and proposals are due October 15th, 2021.

On or about May 7, 2021, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2021" (NNH21ZDA001N) will be posted on the NASA research opportunity homepage at http://solicitation.nasaprs.com/ROSES2021.

Questions concerning A.17 ARCSIX may be directed to Hal Maring (Radiation Sciences Program) at hal.maring@nasa.gov and Thorsten Markus (Cryosphere Program) at thorsten.markus@nasa.gov.
