Research Project: Interfacing the SMAP Cal/Val and Applications Plans

Location: Southwest Watershed Research Center

Project Number: 2022-13610-012-05-I
Project Type: Interagency Reimbursable Agreement

Start Date: Oct 1, 2013
End Date: Sep 6, 2018

The goal of this proposal is to provide continuity and guidance to the SMAP Applications Program as the mission turns its focuses from algorithm development to calibration, validation and utilization of Level 1-4 SMAP science data products. Deliverables will be 1) an increase in total and international members of the SMAP AppWG, 2) addition of SMAP Early Adopters with affiliations in Asia, S. America, Australia and Africa, 3) increased access/use of SMAP Cal/Val datasets for applications research, and 4) coordinated applications and Cal/Val efforts with the SMAP and ESA Fluorescence Explorer (FLEX) missions. The 1st-year activities will entail intensive travel to make contacts that can help realize the proposed objectives. Post-launch (2nd year) work during the in-orbit checkout and Cal/Val phase will be focused on enabling applications demonstrations. The deliverables will maximize entrainment of SMAP mission data in application users’ models, processes and decision support systems.

The proposed approach hinges largely on face-to-face interactions with users through Applications Workshops, Tutorials, Focus Sessions and Town Halls in international venues, and by leveraging SMAP affiliates – Science Definition Team (and new Science Team) members, the SMAP Cal/Val Working Group and the SMAP AppWG – to liaison with the international applications community and identify decision makers. Specifically, the PI proposes to initiate SMAP Focus Sessions with the ESA/CEOS TIGER Initiative entitled “looking for water in Africa” and with the UN Convention to Combat Desertification (UNCCD) which carries a specific mandate focused on Africa, the UN Framework Convention on Climate Change (UNFCCC) which lists soil moisture as an Essential Climate Variable (ECV) and supports work in Africa, and the UN Food and Agriculture Organization (FAO) which reported a food and nutrition crisis in the Sahel and was identified by SMAP as a “key, mature” user group. The PI proposes a SMAP/FLEX Tutorial to coordinate mission applications and Cal/Val early in the development of the FLEX mission.
