AC4 is a competitive research program, which solicits research proposals on an annual basis, starting with the FY2013 announcement released during summer of 2012. In addition, occasionally, the program participates in an interagency call for proposals. Recent solicitations and research priorities are listed below.
Interagency carbon cycle call for proposals (under NASA ROSES)
The carbon cycle interagency call for proposals under NASAROSES is now open. NOAA's participation in the call (through our AC4 program) focuses on "Carbon dynamics within urban-suburban-forested-agricultural landscapes", but the full solicitations includes other topics within carbon cycle.
The link to the solicitation is the following:
The proposal due dates are May 1, 2013 for Step 1 (Letters of Intent) and July 31, 2013 for Step 2 (full proposals).
