The St3TART project aims to provide a supply of fiducial reference measurements (FRMs) in support of the ESA Sentinel-3 (S3) Mission Cal/Val activities through the preparation of a roadmap and a preliminary proof of concept on terrestrial surfaces of interest, i.e. inland water bodies (lakes, reservoirs, rivers, including estuarine areas), sea ice and land ice areas (ice sheets, mountain glaciers).
Project activities will rely on different fields of expertise, both specific and transversal. The specific activities are divided into three thematic areas:
o Hydrology: The primary parameter of interest is water level, and the verification of S3 products may also consider other derived parameters such as river flow and lake water storage variations.
o Sea ice: the main parameters of interest are sea ice thickness and freeboard, as well as the depth of snow depth over sea ice.
o Land ice: the parameter of interest is the land ice topography.
