The Data-Driven Performance Assessment of Altimeters and Radiometers for Next-Generation ESA Altimetry Missions project (DPAAR), presented in this work, establishes a framework with a collection of tools to assess the main performance aspects of a multi-frequency altimeter and an enhanced band microwave radiometer onboard of the future Next Generation Copernicus Sentinel-6 (S6-NG) mission, and provide support for the Phase-0 preliminary design activities, which focus on mission analysis and needs identification constituting the very early assessment stage of the S6-NG mission. The primary strength of this project is not only to rely on accurate simulations and modeling but also on actual measurements. A number of metrics and test cases are implemented to perform both simulation and data-driven evaluation of the altimeter and microwave radiometer, and provide a metrological uncertainty assessment for the different mission characteristics and sizing orbits.

摘要

The Data-Driven Performance Assessment of Altimeters and Radiometers for Next-Generation ESA Altimetry Missions project (DPAAR), presented in this work, establishes a framework with a collection of tools to assess the main performance aspects of a multi-frequency altimeter and an enhanced band microwave radiometer onboard of the future Next Generation Copernicus Sentinel-6 (S6-NG) mission, and provide support for the Phase-0 preliminary design activities, which focus on mission analysis and needs identification constituting the very early assessment stage of the S6-NG mission. The primary strength of this project is not only to rely on accurate simulations and modeling but also on actual measurements. A number of metrics and test cases are implemented to perform both simulation and data-driven evaluation of the altimeter and microwave radiometer, and provide a metrological uncertainty assessment for the different mission characteristics and sizing orbits.
