Integrated Multi-Mission Altimeter Data for Climate Research by NASA/GSFC

This project, led by PI Richard Ray at NASA/GSFC, focuses on developing a consistent time series of Sea Surface Height (SSH) Climate Data Records from multi-mission altimeter data. The objective is to meet stringent accuracy requirements necessary for climate research, addressing climate variability and change. Key milestones include precise orbit determination, multidisciplinary calibration, and validation procedures. The refined strategy aims to deliver validated altimetry products for ocean dynamics analysis, facilitating the evolution of geophysical models and contributing to peer-reviewed scientific publications.
