A.23 Terrestrial Hydrology POC Change

The NASA 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 NASA THP is a component of the Global Water and Energy Cycle Focus Area, see Section 2.4 of A.1, the Earth Science Research Program Overview.

This year A.23 Terrestrial Hydrology encourages proposers to significantly leverage SnowEx data either to:

  • Advance remote sensing of snow water equivalent (SWE), or
  • Understand changing influences on snowpack dynamics, especially snowmelt.

For either of these two objectives, proposers are reminded that THP seeks capabilities that have global scale implementation and/or applicability.

For the first objective (to improve observational capability of snow water equivalent), proposals must clearly explain how its techniques would result in SWE characterization that would be a significant improvement over currently available large-scale snow water equivalent data, both those available from direct observations or model-based reanalysis products. Research for this objective, in alignment with SnowEx observations and THP priorities, should be rooted in one of three types of remote sensing:

  • Multi-frequency, Active/Passive microwave
  • L-band SAR observations, which will be provided by NISAR
  • Spaceborne Lidar

March 26, 2024. The point of contact (POC) for A.23 Terrestrial Hydrology has changed. The new POC is Craig Ferguson, who may be reached at craig.r.ferguson@nasa.gov. The due dates remain unchanged: NOIs are requested by June 27, 2024, and proposals are due August 8, 2024.
