NASA ROSES-17 Amendment 7: Delay of due date for A.25 Terrestrial Hydrology

Status Report From: NASA Science Mission Directorate
Posted: Tuesday, May 2, 2017

ROSES-17 Amendment 7: Delay of due dates for Terrestrial Hydrology, program element A.25.
The Terrestrial Hydrology Program (THP) has the scientific objective to use remote sensing to develop a predictive understanding of the role of water in land-atmosphere interactions and to further the scientific basis of water resources management. The THP is a component of the Global Water and Energy Cycle Focus Area (see Section 2.4 of program element A.1).
THP uses NASA’s unique view from space to study hydrologic processes associated with runoff production, hydrologic fluxes at the land-air interface, and terrestrial water stores. THP works in concert with other Earth Science Division (ESD) programs, also studying the global water cycle (e.g., precipitation, physical oceanography), to describe and understand the connections between the cycle’s different parts. THP fosters the development of hydrologic remote sensing theory, the scientific basis for new hydrologic satellite missions, hydrologic remote sensing field experiments, and the interface of hydrology with other disciplines. Particular emphasis is placed on the application of satellite-based remotely sensed data for characterizing, understanding, and predicting the terrestrially linked components of the hydrologic cycle and the dynamics of large-scale river basins. THP furthers study of the relationship between satellite interferometric measurements of surface deformation and changes in underground water stores. THP is currently focused on research relating to multiple missions, either currently operating, such as Global Precipitation Measurement (GPM) and Soil Moisture Active Passive (SMAP), or in planning and development, such as Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) and Surface Water Ocean Topography (SWOT). THP projects are also extensively using data collected at previous or current field campaigns and projects, such as SMAPVEX (, AirMOSS (, SnowEx (, or numerous others, both national and international.
This amendment delays the due dates for this Program Element to allow more time for SnowEx data collected in February 2017 to be prepared and released to the community. Notices of Intent are now requested by June 28, 2017, and proposals are now due August 3, 2017.
On or about May 2, 2017, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2017" (NNH17ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on the RSS feed at:
