ROSES-15 Amendment 29: Science Utilization of Soil Moisture Active-Passive (SMAP) Mission, primarily using 36 km passive product.

The Soil Moisture Active-Passive (SMAP) satellite launched on January 31, 2015, and Program element A.22 Science Utilization of the Soil Moisture Active-Passive Mission was released as part of ROSES-2015 in mid-February. The SMAP mission started taking science data in April and the radar instrument functioned nominally until July 7, when it stopped returning data. Level one data for both instruments (i.e., backscatters and radiances) can be found at the NASA data archives. With the loss of SMAP’s radar, NASA is interested in alternative methods to downscale the radiometer soil moisture to finer spatial scales. Investigators who previously submitted proposals to this program element and wish to submit modified proposals must withdraw their previous submissions and resubmit the modified proposal. Investigators who wish to have their previous submission to this program element considered without modification need not resubmit.

Notices of Intent are requested by December 2, 2015. Proposals are due January 20, 2016.

On or about October 19, 2015, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2015” (NNH15ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on the RSS feed at:
