The main goals of the GARCA project are:
(1) To develop a tool capable to simulate GNSS-R data products for various instrument implementations using state-of-the-art techniques, including GEROS phase-A candidates, up to Level-1 observables and Level-2 geophysical data products, which will be freely and easily accessible to the interdisciplinary scientific GEROS community.
(2) To study the compliance of different GEROS implementations with respect to the Mission Requirements, and study the optimization of its geophysical data products.
(3) To study the impact of the GEROS-ISS data products on the current Global Ocean observation system and its synergies with existing satellite missions.
(4) To foster a broad GEROS-ISS scientific community, as a way to promote and advertise the concept and its potential, and as a way to promote feed-back from possible future interdisciplinary data users with different levels of expertise and interests.
