Instruments | Orbit | Objectives |
The Sentinel-3 orbit provides an optimal compromise between spatial and temporal sampling for capturing mesoscale ocean structures, offering an improvement on SSH mapping error of up to 44% over Jason due to improved spatial sampling and 8% over the Envisat 35-day orbit due to better temporal sampling.
