2018年，我们庆祝了雷达测高25年的发展，以及这种方法在全球和沿海海洋学，水文学，大地测量学和冰冻圈科学领域取得的进展。许多具有象征意义的重大事件都庆祝了这些发展，例如，在意大利的威尼斯，第15年（2006年）和第20年（2012年）的进展，最近，在2018年，在葡萄牙的蓬塔德尔加达，雷达测高25年的进展。在后一次会议上，决定收集参与世界各地测高界的科学家、工程师和管理人员的贡献，以描述测高的现状，并为未来的测高提出建议。本文总结了所收集的贡献和建议，并为未来的使命设计，研究活动和可持续的业务雷达测高数据开发提供指导。所提出的建议对于进一步优化通过测高进行海洋观测的科学和业务进展至关重要，包括对测高测量的空间和时间分辨率、准确性和连续性的要求。文件中还提到了一些新的挑战和新的机会，这些挑战和机会对于高纬度观测、沿海海洋学、冰冻圈研究和水文学特别重要。本文首先介绍了地球系统科学，包括海洋动力学，海平面，沿海海洋，水文学，冰冻圈和极地海洋和“绿色”海洋，从地球化学扩展到海洋生态学的前沿。应用程序在随后的一节中描述，其中包括业务海洋学，天气，飓风波浪和风预报，气候预测。第四节介绍了仪器的发展和卫星任务的演变。第五节涵盖高度计提供的关键观测及其潜在的补充，从其他地球观测测量到现场数据。第6节确定了数据和方法，并为湿对流层校正、轨道和其他大地测量要求、平均海面、大地水准面和平均动态地形、校准和验证、数据准确性、数据访问和处理（包括DUACS系统）提供了一些精度和分辨率要求。第7节对规模、整合、人工智能和能力建设（教育和培训）进行了横向观察。第8节审查了方案问题，然后是结论。(c)2021年空间研委会。由Elsevier B.

In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and provides guidance for future mission design, research activities, and sustainable operational radar altimetry data exploitation. Recommendations provided are fundamental for optimizing further scientific and operational advances of oceanographic observations by altimetry, including requirements for spatial and temporal resolution of altimetric measurements, their accuracy and continuity. There are also new challenges and new openings mentioned in the paper that are particularly crucial for observations at higher latitudes, for coastal oceanography, for cryospheric studies and for hydrology. The paper starts with a general introduction followed by a section on Earth System Science including Ocean Dynamics, Sea Level, the Coastal Ocean, Hydrology, the Cryosphere and Polar Oceans and the "Green" Ocean, extending the frontier from biogeochemistry to marine ecology. Applications are described in a subsequent section, which covers Operational Oceanography, Weather, Hurricane Wave and Wind Forecasting, Climate projection. Instruments' development and satellite missions' evolutions are described in a fourth section. A fifth section covers the key observations that altimeters provide and their potential complements, from other Earth observation measurements to in situ data. Section 6 identifies the data and methods and provides some accuracy and resolution requirements for the wet tropospheric correction, the orbit and other geodetic requirements, the Mean Sea Surface, Geoid and Mean Dynamic Topography, Calibration and Validation, data accuracy, data access and handling (including the DUACS system). Section 7 brings a transversal view on scales, integration, artificial intelligence, and capacity building (education and training). Section 8 reviews the programmatic issues followed by a conclusion. (c) 2021 COSPAR. Published by Elsevier B.V.
