TL;DR: Sentinel-3 as mentioned in this paper is an Earth observation satellite mission specifically designed for Global Monitoring for Environment and Security (GMES) to ensure the long-term collection and operational delivery of high-quality measurements to GMES ocean, land, and atmospheric services, while contributing to the emergency and security services.

TL;DR: In 2018, the 25th year of development of radar altimetry was celebrated and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences as discussed by the authors.

TL;DR: The 5 cm orbit accuracy requirement in 3D is fulfilled according to the results of the orbit comparisons between the different orbit solutions from the QWG, and an error in the given geometry information about the satellite is found.

TL;DR: In this article, the Envisat microwave radiometer is designed to correct the satellite altimeter data for the excess path delay resulting from tropospheric humidity, and neural networks have been used to formulate the inversion algorithm to retrieve this quantity from the measured brightness temperatures.
