SMAP is implemented as a directed mission within the NASA Earth Systematic Mission Program. The SMAP project is managed by the Jet Propulsion Laboratory (JPL) with participation by the Goddard Space Flight Center (GSFC).

• JPL is responsible for project management, system engineering, instrument management, the radar instrument, mission operations and the ground data system, science data processing, and delivery of science data products to a designated archive for public distribution.

• GSFC is responsible for the radiometer instrument, science data processing, and delivery of science data products to a designated archive for public distribution.

Science Definition Team

A SMAP Science Definition Team (SDT) has been selected by NASA. The SDT is responsible for advising the project on science requirements, science product definition, science algorithms, calibration/validation planning and implementation, and for publishing science results and supporting education and public outreach for the project.

SDT Working Groups

Working Groups have been established as a means to enable broad science and applications community input to the SMAP mission. The working groups are led by Science Definition Team members and provide forums for information exchange on issues related to SMAP science and applications goals and objectives. The working groups communicate via email and at meetings, conference sessions, workshops, and other venues. There are four current working groups on:

• Algorithms
• Calibration & Validation (Cal/Val)
• Radio-Frequency Interference (RFI)
• Applications
